    摘要: A warp rearrangement device includes a multi-layer thread tension mechanism (20) that holds a plurality of warp sheets (12,13), from different warp beams (10,11), together at a warp-beam side holding position (21) and separate (25,26) at the thread tip side of the warp sheets so that the sheets are supported in a radial configuration centered on the warp-beam side holding position (21). A thread separation mechanism (30) separates warp threads (14) one at a time from optionally selected ones of the warp sheets (12,13). A thread end transport mechanism (40) catches the thread end of each separated warp thread and a thread-end holding portion (40a) transports the caught warp threads to a leasing mechanism (50) that leases the warp threads. Transportation is three-dimensional, centered on the warp-beam-side holding position (21), without changing thread length between the warp-beam-side holding position (21) and the thread-end holding portion (40a). A thread end fixing mechanism (60) fixes the thread end of leased warp threads.

    摘要: This yarn-clamping device (6) comprises a support member (166,186) forming a support surface extending along a longitudinal axis (X); a clamping bar (120) including a toothed surface (128) and a clamping surface (126) which faces the support surface along a transverse axis (Z), a first pressing rail (112) provided with a first complementary toothed surface (146) for cooperating with the toothed surface (128) of the clamping bar; and a first drive unit (132) for moving the first pressing rail (112) between a released position and a holding position, so that its first complementary toothed surface (146) cooperates with the toothed surface of the clamping bar to move the clamping surface (126) between a first open position, and a second closed position. The yarn-clamping device (6) also comprises a second pressing rail (114) provided with a second complementary toothed surface (148) for cooperating with the toothed surface (128) of the clamping bar (120) and a second drive unit (134) for moving the second pressing rail (114) between a released position and a holding position, so that the second complementary toothed surface (148) cooperates with the toothed surface of the clamping bar to move the clamping surface between the first open position and the second closed position. The first complementary toothed surface (146) faces a first longitudinal portion (128P1) of the toothed surface (128) of the clamping bar (120) and the second complementary toothed surface (148) faces a second longitudinal portion (128P2) of this toothed surface. The first and second complementary toothed surfaces (146, 148) are adjacent along the longitudinal axis (X) and they are moved, from their released positions to their holding positions, in the same longitudinal direction, for moving the clamping surface (126) from its first open position to its second closed position.

    摘要: The invention relates to a method for forming a yarn rope, said yarn rope comprising a bundle of axial yarns (1,3) extending in an axial direction (A) and at least one cross yarn loop (13,15) inserted in the bundle of axial yarns (1,3) and extending in a cross direction (C), the cross direction (C) being orientated transversely, in particular perpendicularly, to the axial direction (A), wherein the method comprises the steps of receiving a plurality of separate axial yarns (1,3), creating a first insertion gap confined between the axial yarns and extending in cross direction (C), inserting a first cross yarn (13) in the first insertion gap for forming first under portions (35) and over portions (33) with respect to said axial yarns (1,3), creating a second insertion gap confined between the axial yarns (1,3) and extending in cross direction(C), inserting a second cross yarn (15) in the second insertion gap for forming second under portions (39) and over portions (37) with respect to said axial yarns (1,3), and forming the cross yarn loop by connecting the inserted first and second cross yarn (13, 15) with each other, wherein at least the step of inserting the first and/or second cross yarn (13, 15) is motor driven in particular according to a process control sequence.
