Abstract: A warping system for reducing tension in a plurality of yarn ends wound by the warping system onto an outer diameter of a beam. The warping system minimizes the number of contact points as yarn is pulled off of yarn packages in a creel and wound onto the beam. After exiting a tube, yarn passes over a roller and an expansion comb before being wound onto the beam. The yarn extends between the roller and the beam substantially in a yarn plane. The yarn can contact the warping system at only one contact point between the roller and the beam.

Said creel comprises at least one dynamic yarn tension device (6) which is associated with each winding head and at which a variable braking force is applied to the yarn to produce a predetermined yarn tension. Each yarn tension device (6) can be activated by means of an associated drive motor (20). Said creel (2) comprises a control device for controlling the yarn tension based on the angular speed or the yarn speed during a start-up and/or an interruption of the winding machine (3), as well as a regulator (25) for regulating the yarn tension during the normal stationary phase of the winding machine (3). The control device and the regulator (25) are designed such that the yarn tension or the output tension of each yarn can be maintained at a substantially constant level relative to a setpoint value.

Abstract: An apparatus and method for winding a sheet of aligned parallel yarns onto a beam is described. The beam winder utilizes a circularly arced yarn spool rack that feeds each yarn to an alignment comb through associated guide tubes. The distance between each spool of yarn and the alignment comb is substantially the same for all spools of yarn, thereby equalizing the force necessary to pull them to the comb. Next, the aligned sheet of material is preshrunk using heated rollers and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.

Abstract: A supply spool supplies a weft thread through an adjustable actuated thread brake and a thread tension sensor to a weft thread accumulator, from which an accumulated insertion length of the thread is provided to a weft insertion device. The tension sensor provides a measured actual thread tension signal to a control arrangement, which compares the actual tension to a selected rated tension, and, dependent on the deviation therebetween, provides a control signal to an actuator of the thread brake, so that the actual thread tension constantly corresponds to the selected rated tension. Another sensor provides a signal indicating a change from an empty spool to a full spool. Responsive thereto, the control arrangement actuates the thread brake to an adjustable starting brake setting as a coarse adjustment. Then the self-regulating fine adjustment is continued. A constant winding tension and thread accumulation length are achieved in the thread accumulator.

Abstract: A tension device is utilized for equalizing, or at least reducing differentials in tension across strands in a web. The device utilizes an overfeed roll which rotates faster than the speed of feeding the web. Strands at the desired tension, or less, slip about the exterior surface of the overfeed roll. Strands which are greater than the desired tension have sufficient friction to be rotated, at least temporarily, by the overfeed roll to thereby create slack in the higher tension strands to equalize the tension relative to the other strands. Feedback from feed rolls, support rolls, and/or the overfeed roll may be utilized to adjust the speed of the overfeed roll.

Abstract: A yarn tightening element for a weaving machine, comprising a passage (16) for a yarn (15) and a contact means (2) to transmit a tightening force to a yarn (15) moving along through this passage, the passage (16) being not bordered on at least one side of the plane of movement of the yarn (15) or comprises a boundary (14) that is interrupted across its width, so that a part of the yarn (15) running through from that side of the plane of movement, via the interruption (17), can be made to co-operate with the contact means (2). Said boundary is, for instance, formed by one or more fingers (14) directed downwards, while said interruption (17) of this boundary (14) is formed between the extremities of each finger (14) and a part (8) of the yarn tightening element. Such a yarn tightening element can be placed on a yarn very easily and quickly by means of a hooking on movement and be removed again by means of an equally simple hooking off movement.

Abstract: At least one thread tension sensor for each thread is provided on a winding machine. The actual value of thread tension is measured for each thread. The actual value is compared with a specified value in a comparator device and, in the event of a deviation being determined between the actual value and the specified value, a drive motor is actuated to adjust the thread brake of the thread concerned. This arrangement allows for the maintaining of a constant thread tension by a control circuit. The thread tension sensor can be used not only to control the thread tension, but also to monitor the specified thread tension range, and as a thread break monitor.

Abstract: A device for tensioning and drawing back warp yarns brought from a creel to a weaving machine. The tensioning and drawing back device keeps tension and if necessary draws back warp yarns (2) led from a bobbin (1) to a weaving machine. A supporting body (6) has a curved friction surface to support the warp yarn (2) between the bobbin (1) and the weaving machine. A first (7) and a second tensioning element (8) exert a tensile force on the warp yarn (2), respectively, in front of and behind the curved friction surface (6). The tensioning elements (7), (8) can be suspended from the warp yarn (2) and for example only through their own weight may exert this tensile force. This device easily draws back the warp yarn (2) out of the weaving area. The replacement of a bobbin (1) occurs without interruption or disturbance of the weaving process.

Abstract: A method of winding yarn into hanks, comprising the steps of loading a beam having a sheet of parallel ends of yarn wound thereon onto a rotatable beam stand; unwinding the sheet from the beam and passing the sheet through a nip between two reciprocating rolls; separating the parallel ends of yarn in the sheet from each other; and guiding each of the separated ends of yarn to a rotatable reel. The ends of yarn are then wound onto the rotatable reel by rotating the beam to release the sheet wound thereon; rotating the interacting rolls to draw the sheet through the nip; and rotating the reel to wind each separated end of yarn onto the reel. The rotational velocity of the beam and of the reciprocating rolls are controlled so as to keep the tension on the sheet of yarns below a defined value. By controlling tension, one reduces the likelihood of thread breakage and causes the yarns to be wound onto the reels in the form of loose hanks.

Abstract: Winding device for threads from V-creels, from the bobbins of which the threads are drawn off via pre-looping bars and through a comb, and wound on a winding shaft of the winding device, where the pre-looping bars near the winding device have more threads looped around them and those farther away have fewer, and their degree of looping is centrally adjustable. At least one measuring device is placed beyond the comb in the direction of travel of the threads to determine tension in the threads and central adjustment of the pre-looping bars is controlled in relation to the result of measurement. To permit automatic resetting of the pre-looping bars independently of the material and the running speed of the threads in winding devices of different kinds, the winding device is constructed such that the pre-looping bars are divided at least on one side of a creel into successive functional groups to at least one of which is allocated a measuring device to determine the tension in threads of this group.

The device can furthermore comprise preferably detachable tension spindles (11), (12) at the entrance to the disk yarn brakes (2) and at the exit from the disk yarn brakes (2).

Abstract: In the event of an interruption of the weaving process and in the case of weaving-technical operations, such as tabby weaving and unraveling, a trailing of warp thread bobbins and thus a trailing of warp threads which are withdrawn from the bobbins and form a warp thread family, cannot be avoided without significant expenditures. The trailing results in a so-called trailing length in the thread family which, unless it is correspondingly taken up and correspondingly released during the new start of the weaving process, results in an overstretching of the warp thread family during a starting operation of the bobbins. This disadvantage is avoided by deflecting the thread family within a feeding stand, in the event of a weaving stop, in a controlled manner from a reference plane into at least one defined position. At the new start of the weaving process, the deflection is eliminated in a controlled manner.

Abstract: A yarn package holder on a creel, with a mechanism for rapidly stopping the yarn package holder once yarn is no longer being drawn. The mechanism has a pivoted member, one end of which carries a transverse braking control arm that overlies the yarn, and the other end of which is secured to an end of a tensioning cord wrapped at least once around a pulley on the yarn package holder. When yarn is being drawn, the braking control arm is lifted, which has the effect the loosening the cord around the pulley so that the braking effect is small. When yarn is no longer drawn, the braking control arm drops, which has the effect of tightening the cord around the pulley and rapidly stopping the yarn package holder.

Abstract: A warp formed of a multiplicity of parallel filaments is wound on a warp beam by an apparatus having a supply of the warp, a transport roller, and an adjustment roller adjacent the transport roller and movable between a holding position engaging the transport roller and a winding position spaced therefrom. The warp extends from the supply along a path around the transport roller, hen around the adjustment roller, and then around the warp beam. The beam and transport roller are rotated to displace the warp along the path and wind it up on the beam while maintaining the adjustment roller in the winding position. Tension is detected in the warp at least during winding of the warp on the beam and the adjustment roller is displaced during winding of the warp on the beam in a predetermined first direction transverse to the path to increase and decrease the tension to maintain the tension within a predetermined range when the adjustment roller is not in the holding position.

Abstract: After yarn breakage, yarn loops are formed in an accumulator device (3) by rollers (13, 13') that are able to be displaced in relation to each other. The beam is rotated in reverse at a specific reverse speed (c) which is less than the accumulation speed of the accumulator rollers (13, 13'). The length difference arising from the difference between both the speeds is compensated by further withdrawal of yarns (a) from the creel (1) while the yarns are subjected to a defined braking tension of the individual yarn tensioners (7). Complex controls and speed synchronization are thus avoided.

Via an oscillatory motion generator, such as an electromagnet, mechanical or other device, the support or bearing means is set into mechanical oscillation that is essentially axial to the brake disks or in other words parallel to the axis of rotation defined by the rotation of the brake disks. The brake disks are carried along only slightly or not at all by the support or bearing device and the oscillatory motion generator.

This slide (30) is coupled by a gear to the rotary hollow insert (42 ). This thread tightener allows the braking force to be very finely adjusted and may have very small dimensions.

Abstract: A method and apparatus for winding yarn to produce a wound yarn package having a variable density profile. The variable density profile in the wound yarn is produced by variably tensioning the yarn during the winding process by an electrical apparatus which is responsive to a programmed control signal to provide variable tension on the yarn. The density profile thus produced is preferably a progressively variable density profile. In a preferred embodiment, the method is carried out with a precision winding machine with an electromagnetic tensioner. A controlled sequence of control signals is applied to the tensioner to provide a correspondingly varying tension on the yarn. The application of controlled tensioning to dyeing beams by progressively increasing tensioning warping yarn along the length of the beam has also shown improved results in resisting dye liquor channeling and blowout and permitted a beam geometry with a greater capacity.

Each of the supply spools is rotatably mounted on the backboard, and each of the supply spools holds one end of an individual superconductor filament. The opposite ends of the filaments are attached to a single rotatable wire take-up spool. Accordingly, the wire take-up spool can be rotated to transfer the filaments from the respective supply spools to the take-up spool. A combiner board is mounted on the backboard normal to the backboard between the supply spools and the wire take-up spool. The combiner board receives each of the superconductor filaments as the filaments are transferred from the respective supply spools to the take-up spool to guide the filaments into a layer of aligned superconductor filaments. Additionally, each supply spool has a tension controller individually associated with the respective supply spool.

There is also provided a warping arrangement for the foregoing procedure in which the warp sheet path to the driven warp beam is provided with a turning roller, and comprises a measuring arrangement for transmitting the warp beam diameter and a rotation counter. The object of the invention being to provide in a simple manner, a number similarly wound beams.

Abstract: A tension controller for a warping machine maintains a constant yarn tension during a warping operation from the beginning to the end of the warping operation. The tension controller has a brake force control mechanism (240) for controlling the size of the tension applied to the running yarns, and a yarn speed control mechanism (290) for controlling the running speed of the yarns. The brake control input, which is supplied to the yarns brakes, and the running speed of the yarns are so controlled that the actual yarn tension conforms to set or desired tension. When the diameters of the yarn packages are relatively large, a brake force is applied to the yarns, which run at a constant speed, thereby maintaining a constant yarn tension. When the diameters of the yarn packages are relatively small, on the other hand, a constant yarn tension is maintained by reducing the running speed of the yarns while supplying a zero or constant brake force to the yarns.

Preferably a separate drive motor (38) for the leasing device and a cross-wound motor (17) for the oscillating motion of the cross reed (16) is also provided. The independent drive motors make possible automation and programming of the different operational sequences which are necessary for the formation of yarn crossings or the rectification of breakages.

Abstract: A textile machine in the form of a warper for drawing multiple strands from a creel and for winding the strands on a rotatable beam which forms part of the warper. Located between the creel and the beam is a strand guide and tension isolator comprising a motor-driven delivery roller and two nip rollers. Load cells are associated with one of the nip rollers and produce signals which vary substantially linearly as a function of changes in the tension of the strands between the final nip roller and the beam. The load cell signals are used to control the drive motor for the delivery roller so as to cause the motor to reduce the torque applied to the delivery roller when the tension increases and to increase the torque applied to the delivery roller when the tension decreases.

Respective movable jaws movable toward and away from the respective stationary jaws can be actuated via respective springs to press against the yarns on the respective surfaces with a force capable of varying smoothly and steplessly up to a relatively high nominal level corresponding to high tension in the respective yarn. A sensor connected to the deflector responds when the tension in the yarn at the deflector drops below a predetermined low tension, typically to signal a shutdown of the takeup machine so the break can be repaired.

Among the first, second and third thread speeds the two furthest upstream have an adjustable speed ratio. The controller can measure the tension of the threads traveling to the tension roller. This controller is operable to alter the speed ratio in response to the tension of the threads, to hold this tension at a predetermined magnitude.

Abstract: A beaming machine (beamer) suitable to run any common width beam for Raschel-type knitting machines, having three beams or heads with individual traverse settings so that different yarn end counts can be simultaneously wound on each beam. Uniform yarn tension is obtained at each beam by a series of two rollers positioned between the beam and the yarn creel over which each yarn end must pass. An evenly wound beam is thereby obtained for each of the three beams. Doffing time is minimized by the tensioning rollers in conjunction with pigtail-shaped yarn end guides mounted on one of a plurality of reeds adapted for the various end counts capable of being wound by the machine. Yarn breakage is detected by the breaking of a light beam in conjunction with an air sheet generated from an air slit for each beam. An air sheet is directed toward each yarn sheet so as to blow any broken yarn end across the light beam and thereby electronically initiate a shut-down of the beamer.
