  • Patent number: 4974640
    Abstract: A method for removing a loose incorrectly inserted piece of weft thread from the shed in a weaving machine includes the steps of inserting a weft thread into the shed and transporting it through the shed until it extends over the entire length of the shed in order to from a pulling thread. The loose weft thread is then fastened, outside the shed, to the pulling thread. The pulling thread is drawn together with the piece of weft thread fastened to it from the end of the shed located opposite to the end at which the fastening occurred in such a way that the latter piece of weft thread is removed from the fell line in the form of a loop and thereby removed from the shed.

  • Patent number: 4951717
    Abstract: An air jet weaving loom is equipped with an expander table and has a weaving reed forming a weft thread insertion channel. The expander table has an extension reaching toward the channel and preferably to about the center of the channel. The extension has a top surface which forms an elongation of a fabric supporting surface of the expander table. This arrangement assures that the beat-up or interlacing point is always located about centrally in the weft thread insertion channel.

  • Patent number: 4924916
    Abstract: A heddle frame for holding a plurality of heddles comprising a top rail and a bottom rail. Each of the rails has heddle supporting bars attached to them for supporting the heddles within the frame, and the top and bottom rails are held in parallel relationship to each other by end members attached to their adjacent ends. Intermediate the end members is a center brace which may be located in alternative positions within the heddle frame. Each of the rails has an opening to receive the centerbrace and to support it so as to maintain the parallel positions of the top and bottom rails. The holes within the rails are reinforced with steel reinforcing guide tubes which resist the wear of the centerbrace during the use of the heddle frame and protects the rails.

  • Patent number: 4922970
    Abstract: A weft thread inserting gripper for a loom is equipped with a guide element attached to a side wall of the gripper. In order to enable the guide element to properly contact the reed when the gripper moves in the loom shed, the guide element and gripper combination is so constructed that at least the guide element can tilt about a journal axis extending in parallel to the direction of gripper movement. This tilting ability can be achieved by mounting the guide element itself to a gripper side wall for pivoting about the journal axis. The same tilting effect can be achieved by mounting the entire gripper side wall carrying the guide element on such a journal axis. Both possibilities assure an optimal surface contact between the guide element and the respective surface in the loom to provide a quiet and smooth gripper motion.

  • Patent number: 4922967
    Abstract: The torsion bar firing device is provided with a striking lever having an end piece at the distal end which acts directly on the abutment face of a projectile on firing. The striking face of the end piece of the striking lever and/or the abutment face of a projectile may be formed as inclined planes or as convex, concave, or concave-convex surfaces. The direct drive of the projectile by the striking lever reduces the masses to be accelerated and braked. This advantageously influences the energy consumption and the weaving efficiency of the projectile weaving loom. The end piece may be integral with the distal end of the striking lever or may be in the form of a rotatably mounted roller of a trapezium shaped element.

  • Patent number: 4922637
    Abstract: A steam iron press employs first and second members and a lever mechanism connected to a second member and when manually actuated by an operator causing the second member to be moved to any position between a position of maximum separation and a position of engagement with respect to the first member. The second member receives water and converts the water into steam which is expelled through openings therein. A pump connected between the second member and a water reservoir feeds water to the second member. A cam mechanism is connected between the lever mechanism and the pump to only actuate the pump during a predetermined interval t between the instant of time T1 at which the lever mechanism has initiated movement of the second member towards the first member and the instant of time T2 at which the article to be pressed is to be squeezed between the two surfaces.

  • Patent number: 4920621
    Abstract: A method and apparatus for shrink finishing a traveling textile fabric web includes a fabric drawing-in unit, a wetting unit, a fabric stetching unit, a fabric shrinking unit, and a fabric drying unit. Individual drives for each unit are provided, with the drive for the shrinking unit being the main drive and being operated as a function of the lengthwise elongation of the fabric web by the stretching unit to achieve a desired overall degree of lengthwise shrinkage of the fabric web. Automatic control of the system is provided by digital synchronization of the several drives and through moisture sensors which monitor the moisture content in the fabric web in advance of the shrinking unit and after the drying unit and by tension sensors which monitor the actual tension in the web intermediate each successive pair of the units.

  • Patent number: 4914786
    Abstract: In a feeder for a roller gin, locks of seed cotton are pressed against a flexible knobby roller having pockets. Each pocket holds only one seed, thus spacing the seed one from another. A doffing roller adjacent the knobby roller travels at least twice as fast as the knobby roller. This lint and the seed of the cotton are pulled over at transfer edge between the knobby and doffing roller, thereby breaking the locks of seed cotton into individual seed locks which are spaced apart. Thus, the cotton is combed and smoothed and formed into a batt of a single layer of seed locks.

  • Patent number: 4915141
    Abstract: An auxiliary nozzle for an air jet loom, arranged to provide assisting force to a weft yarn picked from a weft inserting nozzle. The auxiliary nozzle is formed with a nozzle opening through which auxiliary air is ejected to enhance the air stream from the weft inserting nozzle. The nozzle opening consists of two lateral opening sections which are spaced and parallel with each other, and an axial opening section connecting the two lateral opening sections with each other. Each lateral opening section extends generally perpendicular to a plane passing through the axis of the auxiliary nozzle. The axial opening section extends generally parallel with the above-mentioned plane. Thus, the nozzle opening is generally H-shaped and extends in the direction of the thickness of the nozzle body of the auxiliary nozzle, thereby stabilizing direction of the auxiliary air ejection from the auxiliary nozzle without being affected by a variation of the air pressure to be supplied to the auxiliary nozzle.

  • Patent number: 4915142
    Abstract: A weft insertion control system for a jet loom includes a weft yarn sensor for sensing a behavior of a forward end of an inserted weft yarn accurately, and a controlling system for controlling a weft inserting condition such as a fluid jet in accordance with the sensed behavior. The weft yarn sensor is arranged to detect at least one of the following first, second and third conditions. The first condition is a condition in which the picked weft yarn is elongated to a greatest length, and the weft forward end is farthest from a main fluid jet nozzle. The second condition is a condition in which the weft end is pulled back most by shrinkage of the weft yarn after the first condition is reached. The third condition is a condition in which the weft yarn is elongated again to a relative maximum length.

  • Patent number: 4913194
    Abstract: A lightweight frame slat for use in a heddle frame assembly. Each of said slats comprises an upper hollow portion and a heddle bar support portion integral with and extending from the hollow elongated portion. The hollow portion is made up of a vertically extending back portion and a vertical front portion so that when the front portion is in place three longitudinal cavities are formed. Adjacent each of the edge of the hollow elongated upper portion is disposed elongated stiffening bars of a carbon fiber reinforced stiffening element. The intermediate cavity between the edge cavities is filled with a strip of ridged foam to add structural stability to the slat without greatly increasing its weight.Extending from, and integral with the back portion of the slat is a heddle bar support portion which has extending from it near its bottom edge two horizontal ledges which define a heddle bar support channel.
