The cross-winding devices are arranged into a multiple number of sections along each of the machine sides. A sleeve transport device is arranged along the cross-winding devices on each machine side to supply empty sleeves to cross-winding devices. A plurality of sleeve stacks are configured to stockpile the empty sleeves. A plurality of sleeve storage devices are arranged along each machine side for distributed intermediate storage of the empty sleeves, wherein each cross-winding device is allocated with a single sleeve storage device, or the plurality of the cross-winding devices in each of the sections are allocated to a single one of the sleeve storage devices.
Abstract:
The invention relates to a double-folding drafting unit, comprising five pairs of rollers, a first, a second, a fourth and a fifth pair of rollers having essentially an identical orientation of the respective axes of the rollers, and a third pair of rollers, which is positioned between the second and the fourth pair of rollers, having an axial direction which is oriented perpendicularly to the axial direction of the other pairs of rollers, an apron being guided in each case around each roller of the first and third pair of rollers and at least one reversing rail assigned to the respective roller, and an apron being guided around each roller of the fourth pair of rollers and around a reversing rail in front of and a reversing rail behind the respective roller. The invention relates, furthermore, to a spin-knitting machine comprising at least two double-folding drafting units.
Abstract:
The invention relates to a double-folding drafting unit, comprising five pairs of rollers (WI/W1, WII/W2, WIII/W3, WIV/W4, WV/W5), a first (WI/W1), a second (WII/W2), a fourth (WIV/W4) and a fifth (WV/W5) pair of rollers having essentially an identical orientation of the respective axes of the rollers (WI, W1, WII, W2, WIV, W4, WV, W5), and a third pair of rollers (WIII/W3), which is positioned between the second (WII/W2) and the fourth (WIV/W4) pair of rollers, having an axial direction which is oriented perpendicularly to the axial direction of the other pairs of rollers (WI/W1, WII/W2, WIV/W4, WV/W5), an apron (R1, R1, RIII, R3) being guided in each case around each roller (WI, W1, WIII, W3) of the first and third pair of rollers (WI/W1, WIII/W3) and at least one reversing rail (WSI, WS1, WSIII, WS3) assigned to the respective roller (WI, W1, WIII, W3), and an apron (RIV, R4) being guided around each roller (WIV, W4) of the fourth pair of rollers (WIV/W4) and around a reversing rail (WSIV-1, WS4-1) in front of and a reversing rail (WSIV-2, WS4-2) behind the respective roller (WIV, W4). The invention relates, furthermore, to a spin-knitting machine comprising at least two double-folding drafting units.
Abstract:
The instant invention relates to a compression bar such as is used in the main drafting zone of drafting rollers of the textile industry. The invention considerably reduces deposits on a compression bar. The fixed compression bar has a rectangular cross-section, with its narrow faces being rounded off. On the other hand, the compression bar is rotatably mounted about its longitudinal axis, whereby the compression bar has preferably a circular cross-section.
Abstract:
A textile drawing machine has interchangeable drawing heads mounted between the feed rollers and the drawing rollers, to enable it to treat different types of textile fibres. The heads are readily replaceable in a frame of the machine and have support and drive members engaging support and drive members on the frame.
Abstract:
In a stretch yarn (1) comprising a stretchable core (2) covered by an inelastic fibers sheath (3) the stretchable core (2) comprises first and second fibers (4, 5) that have elastic properties, the first fiber (4) is an elastomer and the second fiber (5) is a polyester based (co)polymer, the amount of the second fiber being in the range of 60-90% (w/w) of the total weight of the fibers of the stretchable core (2); the first and second fibers are connected together at least at a plurality of points (P).
Abstract:
Methods for making yarns are provided which include the steps of supplying continuous polymer filaments, detaching from at least a part of the continuous polymer filaments, and at least one continuous reinforcement filament, a plurality of discontinuous polymer fibers and of discontinuous reinforcement fibers to obtain a composite sliver, and twisting the composite sliver to obtain a roving from which yarn may be obtained. Yarns produced by such methods as well as textiles, fabrics and garments which include such yarns are also provided. Such yarns may be particularly useful in the production of, for example, protective gloves.
Abstract:
The combing machine is provided with a plurality of combing devices for delivering a plurality of combed slivers as well as a drafting system for receiving and drafting the combed slivers for delivery to a can press. A measuring device is provided to measure the thickness of the sliver delivered to the drafting system and to deliver a signal to a control unit which, in turn, regulates the drafting of the sliver within the drafting system in accordance with the received signal in order to obtain an evened combed sliver.
Abstract:
The drawframe has a preliminary drafting zone with a draft of from 4 to 8 as well as a main drafting zone with a draft of at least 30. In addition, a deflecting rod is disposed in the preliminary drafting zone in order to deflect the flow of fiber by about 1 millimeter. The deflecting rod is positioned centrally between the nips of the rollers defining the preliminary drafting zone. The guide surface of the deflecting rod may be convexly rounded not only transversely but also longitudinally in guiding the fiber flow thereover.
Abstract:
A machine for blending, matting, shortening or sizing natural or artificial fibers, in which the work is performed by groups or trains of three rollers. A first working stage has a single head delivering two slivers and in which the twin bearing rollers are of large size, the two slivers emerging from the single head being fed axially or perpendicularly by directional and juxtaposing members towards a second working stage in a single lap, the width of which is at least 50% less than the width of an individual sliver. The second working stage has a reducing head which comprises a plurality of trains with twin lower retaining and traction rollers, respectively, mounted overhung on frames, adjustably spaced from one another.
