摘要:
A device and a method for manufacturing a synthetic yarn, in which at least two yarn plugs (1), (2), (3) are produced by texturing, are placed in a first zone (A) on the cooling surface (6c) of a rotating cooling drum (6), moved to a second zone (B) and form more than one winding (I),(II), in which the yarn plugs are kept in the second zone (B) by a gas stream (FB) on the cooling surface (6c), and in which no gas stream or a less powerful gas stream is generated in an intermediate zone (C) in order to prevent the yarn plugs (1), (2), (3) from leaving the second zone (B).
摘要:
A device for cutting off weft yarn (27) during successive weaving cycles, comprising a cutting element (1) and a rotatable detaining element (2c), (13) which is forced to a detaining position by a spring force in order to detain the yarn and can rotate, under the influence of a tensile force exerted by a rapier on the detained yarn, counter to the spring force to a non-detaining position in which the yarn can be moved further towards the cutting element (1) in order to be cut. Such a device is efficient and can be made to be more reliable and more compact than existing devices. The invention also relates to a weaving loom provided with such a device.
摘要:
A coupling device for positioning elements for warp yarns, comprising a male coupling part (1) with a head (8) which, when elastically deformed, can be introduced into a female coupling part (11) via a passage (13) and assumes a larger transverse dimension beyond said passage, so that the head is detained there and the coupling parts (1), (11) are coupled. Beyond this passage (13), the female coupling part (11) comprises an axially displaceable uncoupling body (16) with an opening (17), so that the head can be introduced into this opening (17) and be deformed in the process to such an extent that it can be introduced into the passage (13) in order to uncouple the coupling parts.
摘要:
A weaving method for the double-face weaving of pile fabrics wherein at least five different pile warp threads (12-19), (20-27) with a yarn number of between 6 and 10 Nm final and at least two tension warp threads (8),(9); (10,11) are provided for each warp thread system (100) and for each fabric (28), (29), wherein the weft threads (1,2), (2,3) of each fabric are divided over at least three levels, while the ground weave repeat runs over at least eight insertion cycles (I-VIII), wherein between 200 and 1000 warp thread systems per metre are provided, and at least 16 pile rows per cm are formed in the warp direction.
摘要:
A shed-forming device has elastically deformable selection elements (1) (28a)-(28f) which can be placed in an undeformed position or in a deformed position, electromagnetic selectors (2) which can be actuated in order to place or keep each selection element (1) in successive weaving cycles in one of said positions, and presenting means (3) in order to mechanically deform selection elements (1) in the direction of a selector (2) in each weaving cycle into a presenting position in which they are kept at a distance from the selector (2) by a stop (4), and also relates to a method for positioning selection elements of a shed-forming device in this manner.
摘要:
A spinneret (1) for producing several filaments, comprising a plurality of perforations (2), each of which ends on the bottom side of the spinneret (1) into a respective outlet opening (3) for pressing a thermoplastic there through for forming the filaments, wherein the outlet openings (3) are arranged in rows (5) which extend along a cooling direction (A), from one side of the spinneret (1) to the opposite side, wherein these rows (5) are arranged increasingly close together, away from a line (C), along this cooling direction (A) and through the centre of the spinneret (1).
摘要:
A fabric guiding device (1) for a weaving machine, having automatic clampers (6), (7) to release or secure a bridge, for example an upper bridge (2) and/or a lower bridge (3). On the other hand, a method for releasing and re-clamping a bridge of a fabric guiding device of a weaving machine. Preferably suitable for use in a weaving machine. More particularly, for use in a face-to-face weaving machine.
摘要:
A pulley for installation in a pulley mechanism of a Jacquard machine has a shaft, a housing having two flank bodies, which are provided to fasten the shaft, so that this shaft extends substantially between the flank bodies, and a pulley wheel, which is provided to be arranged between the two flank bodies so as to be directly rotatable around the shaft. The shaft, prior to assembly of the pulley, is provided with cavities and/or projecting portions for the post-assembly axial securement of the flank bodies in both axial directions.
摘要:
A shed forming device for a weaving machine comprising motion systems consisting of hooks that are moveable up and down, transmission elements to transmit the hook motion to a carrier for warp threads, a first force element to exert a downward-directed force on the carrier, and an energy buffer and a second force element to exert a force on an element of the motion system that results in an upward-directed force on the carrier so that the element is so deformed or displaced that the elements of the motion system are kept under tension.
