Abstract: A thread delivery device for a textile machine having a rotatable drum on which a thread issuing from a thread bobbin can be wound tangentially for forming an intermediate thread storage. The drum has a lower thread removal edge over which the thread can be withdrawn tangentially for permitting positive thread delivery. A thread guide member is stationarily positioned radially outside of the drum approximately at the level of the removal edge to guide the withdrawn thread. A thread control element is disposed in engagement with the withdrawn thread at a location between its engagement with the drum and the thread guiding member. The thread control element, which is movable transversely relative to the withdrawal path of the thread, is positioned approximately at the level of the removal edge of the drum and is maintained in this position by its engagement with the withdrawn thread so long as the normal working tension is maintained in the thread.

Abstract: A thread storage and delivery device for textile machines, including a housing having a thread supply device rotatably supported thereon and defining a thread channel, a rotatably supported drum axle, a storage drum, and a gearing arrangement with at least one driven wheel which can be driven by means of a carrier pin carried by the thread supply device so that the drum rolls along on a housing-fixed rolling path. The gearing arrangement couples the storage drum to the thread supply device in such a manner that the storage drum stands still with respect to the housing as the thread supply device is rotatably driven. This gearing arrangement engages the drum axle which is fixedly connected to the storage drum and is supported rotatably on the thread supply device, and the thread channel is arranged at a radial distance from the drum axis and extends substantially rectilinearly.

Abstract: A transport device is provided which is driven by an electromotor and on which more than two bobbin supports are mounted and are movable in common such that the respective bobbin to be unwound can be brought into the required association with respect to a stationary thread eye. A thread scanning device is provided adjacent the unwound thread for detecting the thread as it jumps from the bobbin just emptied to the next bobbin. This thread scanning device is connected with the electromotor such that, when the thread scanning device responds, the motor moves the transport device to such an extent that the next bobbin is brought into the required association with respect to the stationary thread eye.

Abstract: A device for supplying a textile or metallic thread to a processing device. The thread issuing from a storage bobbin is wound tangentially on a storage body and is unwound endwise therefrom beneath a resilient brake ring which abuts a conical support surface on the storage body. The brake ring can be adjusted in the axial direction of the storage body relative to the support surface by means of an adjusting means which can be actuated in response to the thread tension.

Abstract: A thread supply device for a textile machine, which device includes a drum on which a thread is wound to form an intermediate thread storage, and from which the thread is withdrawn over one end of the drum for supply to the textile machine. A brake means is disposed adjacent the withdrawal end of the drum and acts on the unwinding thread for imposing a braking effect thereon. The braking means acts progressively on the unwinding thread as it moves peripherally relative to the drum for either increasing or decreasing the braking effect on the thread, depending upon the relative peripheral direction of movement of the thread.

Abstract: A thread storing and feeding device, particularly for feeding thread in a sewing machine. The device includes a housing having a storage drum mounted thereon. The thread is tangentially fed onto the drum and is withdrawn over the end thereof. A sliding disc movable in the axial direction of the drum moves the thread supply over the drum. A control device is actuated by the sliding disc for controlling a winding drive. The sliding disc is mounted on a pivot lever, of which the end directed away from the sliding disc is tiltably mounted at a distance from the storage drum axle at least approximately equal to the drum radius.

Abstract: A thread delivery device for a textile machine, which device includes a drum upon which a thread can be tangentially wound to form an intermediate thread storage and from which the thread can be unwound axially over an end of the drum. A thread control member is positioned adjacent the withdrawal end of the drum for engaging the withdrawn thread to limit the withdrawal rate of thread from the drum substantially to the rate at which the thread is wound onto the drum to thereby provide a positive thread supply. A thread guide element is disposed adjacent but radially spaced from the drum, and the last thread winding on the drum (that is, the winding which is about to be withdrawn from the drum) is guided around the thread guide element and then back to the drum so that the last winding thus forms a partial winding on the drum. This thread control element thus ensures that two or more windings are not wound off the drum simultaneously.

Abstract: A thread supply device, as for a textile machine, having a stationary thread drum onto which a thread which comes from a storage bobbin can be wound tangentially by means of a winding-on member which rotates around the drum edge for forming an intermediate thread supply on the drum. The thread can be pulled off the drum through a central withdrawal eye. A thread control element is arranged in the area of the withdrawal path of the thread. The thread control element has the form of a hook and is secured on the winding-on member. The hook receives the withdrawal thread in its mouth to limit the thread withdrawal speed to the thread winding-on speed. In the thread withdrawal path, downstream of the hook, there is provided a cut-off eye arranged on a swivel arm which can be swung transversely to the thread path from an operating position into a nonuse or shut-off position. This arm is hinged to the rotating winding-on member and swivels about an axis which is substantially aligned with the axis of the drum.

Abstract: A thread delivery device, preferably for a textile machine, having a fixed drum with a rotatable hollow shaft. A thread from a storage bobbin is delivered from a first face of the drum through the shaft to a second face of the drum. A thread take-up member in the form of a circular take-up disc is rigidly mounted on the shaft adjacent the second face. A thread eyelet is arranged in the vicinity of the edge of the take-up disc for tangentially winding an intermediate supply of thread onto the drum. The intermediate thread supply is movable in the direction of the first face of the drum where the thread is drawn off the drum in the direction of and over the second face and fed to the working elements of the textile machine. An entire annular flange is arranged on the take-up disc, inside of the thread guide, which flange is perpendicular to the disc and projects towards the drum. The flange is concentric with the drum and the section thereof adjacent to the second face.

Abstract: A control device for a textile machine, in particular for a knitting machine having at least one yarn feeding device, with each yarn feeding device being provided with two stop-motion devices each respectively having an electrical stop-motion switch associated therewith. The stop-motion switches of the yarn feeding device are connected to a rectifier circuit such that the two stop-motion switches of the yarn feeding device are supplied with voltage half-waves of different polarity. A control unit is provided which is common to all stop-motion switches and which is capable of surpressing voltage half-waves of one polarity in order to neutralize the stop-motion switch supplied with the voltage halfwaves of said one polarity with reference to a relay which stops the mechanical drive of the textile machine.

Abstract: A thread delivery device for a textile machine in which a member associated with a thread delivery arrangement is driven by a driving belt which in turn is driven by a driving wheel whose effective diameter can be varied to vary the speed of the driving belt. The driving belt is engaged with a running surface associated with the driving wheel. The driving belt is provided with holes therein, and the running surface of the driving wheel is formed by a second driving belt with pins on its outer face which engage in the holes of the first-mentioned driving belt to provide a slip-free connection therebetween. The second driving belt is engaged with and extends between the driving wheel and a further guide or idler wheel.

Abstract: A thread storage and supply device for textile machines comprising a storage drum which is nonrotatably journaled at the free end of an axle, which axle is prevented from rotating by means of a laterally displaced journal pin which extends parallel to the longitudinal direction of the axle and is rotatably positioned in a rotatably journaled disc. The device further comprises a thread supply means which is journaled on the axle, which support means can be set in rotation and which winds the thread upon the storage drum. The rotatably journaled disc is connected, for the purpose of synchronous rotation, to the rotating thread supply means by a connecting pin which is rigidly mounted on the thread supply means and which passes through a radial slot in the rotatably journaled disc. The thread supply means includes a corotational channel for the thread.

Abstract: A thread supply device for a textile machine, in particular a knitting machine, having a thread drum upon which a thread issuing from a thread bobbin can be wound to form an intermediate thread supply and from which the thread can be unwound at an unwinding speed equal to the speed of winding. A winding shaft is set in rotation by a driving means in order to wind the thread up onto the thread drum. The driving means engages the winding shaft via a clutch which can be released when the driving means is at a standstill. The winding shaft is provided with a connection member for engaging an auxiliary driving means for setting the winding shaft in rotation when the clutch is disengaged.
