  • Patent number: 5758395
    Abstract: In a warping machine, once a temporary feed speed for a warping reed is set in synchronism with the speed of rotation of the warping drum, the winding thickness of the warp lap is detected several times and the feed speed is corrected depending on the number of revolutions of the warping drum and the winding thickness that results therefrom. The winding of the warp lap is then completed at the corrected feed speed. During a starting phase, a theoretically correct feed speed for at least the first revolution of the warping drum is derived from warp parameters, such as the total number of threads, the width of the warp and the yarn count. The winding thickness of the first warp section is continuously and contactlessly measured during a learning phase that follows the starting phase, or during the starting phase. For that purpose, a winding thickness measurement arrangement is held at a predetermined, substantially constant distance from the surface of the warp layer that has just been wound.

  • Patent number: 5603146
    Abstract: In a process for the production of short warps, especially pattern weaves, an individual thread (1) of different or the same color is wound up on a wind surface (9,11) sequentially with turns lying next to each other in an individual layer. This layer corresponds to the warp length. A thread guide (4) is movable around the circumferential contour of a wind-up arrangement (2) in the wind plane. A forwarding arrangement further moves the side-by-side wound thread warp at each circuit of the thread guide (4) by an amount equivalent to the thread thickness. The first individual threads (1) are wound on a support surface (11) displaceable orthogonal to the wind plane (10). Each further individual thread (1) is wound onto the previously wound thread warp (18), having been displaced rearwardly by an amount at least equivalent to one thread thickness.

  • Patent number: 5590448
    Abstract: An arrangement can produce short warps, in particular for woven patterns in which threads (1) of different colors are wound onto a winding arrangement in single layers next to each other and sequentially with respect to each other. The arrangement has positioned at one end face (8) of the winding arrangement a thread laying device (4), which rotates around the circumferential contour of the winding arrangement (2). At least one thread (1) is pulled from a spool (14) in a spool magazine (12) and laid off onto a feed arrangement (16) located on the circumference of the winding arrangement (2) in a winding plane. This feed arrangement transports the wound up thread sheet perpendicular to the winding plane by an amount corresponding to the wind growth. The thread sheet, obtained as an endless sheet band in the direction transverse to the winding direction, can be cut open after completion of the thread warp.

  • Patent number: 4893386
    Abstract: An apparatus for producing pattern warps on a cone warping machine comprises a drum, a support, a warping reed and lease rods, means for displacing the lease rods, and a driving means for rotating the drum. There is provided a tong-type gripper (60) for shifting the lease rods (61) axially and in height. The warping reed (25) is displaceably supported as a sliding reed from one central position to both sides, and it may be adjusted vertically with respect to drum (2).

  • Patent number: 4734957
    Abstract: A feed duct (1) for feeding textile fibers to an associated processing machine is disclosed which includes adjustable wall elements (22, 23) to vary the width of the filling chamber (5) of the duct and discharge a fiber web of corresponding width. The adjustable wall elements (22, 23) are displaceable parallel to the side walls (31, 32) of the filling chamber and include lateral wall elements (22a, 23a) which are bent and extend through the side walls to also act as holding elements. Setting elements (26, 28 and 27, 29) adjust the setting of the wall elements and the chamber width. In a duct feed having an oscillating plate 39, adjustable wall elements are provided as double wall elements (43, 44) with a pivotal wall part (45, 46) carried between the double walls of each element. An inclined edge (51) of the double wall elements allows oscillating plate (39) to swing with respect to the adjustable width duct for compaction of fiber.
