... 1354885 Knitting-machines WIRKMASCHINENBAU KARL-MARX-STADT VEB 13 May 1971 [18 May 1970] 23981/70 Heading D1C In a sewing-knitting machine for uniting fibres 4, the teeth 6 of the holding comb are cranked towards the knocking-over comb 7, in the vicinity of the needles. The passage of the fibres is thus abruptly narrowed. The tips of the teeth abut the edge 8a of a support bar 8 as the needles penetrate the fibres. Laps of thread crossing over the teeth can slip over the ends as the fabric is taken-down.

A fleece material

A bulky non-woven fleece material (11) is composed predominately of longitudinal fibres and has on both sides stabilised fleece surfaces with the fibres meanderingly disposed between the fleece surfaces. With the object of rendering the fleece material entirely suitable for recycling while at the same time permitting of rational production the apices (112, 113) of closely adjacent meander loops at the two fleece surfaces are connected to one another by fibre loops (12) drawn from the fibres of the apices and extending substantially parallel to both surfaces. The fibre loops may be in the form of stitches formed by sliding-latch needles (21, 31) which also serve to produce the meandering configuration. Alternatively the fibre loops may be formed by felting needles acting in a direction parallel to the respective sides of the fleece. ...

FILLING EFFECT DESIGNS ON A STITCH-THROUGH FABRIC

DEVICES FOR LAYING LAYERS OF WEFT THREADS

1442695 Cross-laying threads; knitting- machines WIRKMASCHINENBAU KARLMARX-STADT VEB 25 April 1974 [21 May 1973] 18126/74 Headings D1C and D1R An array of weft threads 5 is laid by laying means 2 between thread transport means 4, 4a which are aligned at an angle. The term threads includes slubbings, fleece webs and film webs. The laying means is characterised in that it allows the threads to be hooked simultaneously at each hooking of the weft array. The laid array is preferably transported to a stitch bonding or warp knitting means. In the embodiment of Fig. 1 laying means 2 comprises a beam pivoted at 3 and containing guide holes 13 for warp threads 5. The beam and the pivot are reciprocated by carriage 1. As the carriage moves from transport means 4 the tension in threads 5 holds the beam against stop 7 so that the beam is parallel to transport means 4a. The embodiment of Fig. 2 (not shown) is similar except that the thread laying beam, is normally held by springs (11) in an orientation bisecting the angle α between the thread transport means. As the carriage approaches a transport means 4, 4a a projection (12) of the laying beam strikes a stop (10, 10a), causing the laying beam to pivot against the action of the spring until it is aligned parallel with the transport means. In the embodiment of Fig. 3 the laying means comprises a plate 2 having thread guide slots 13'. Rails 14, 14a enclosing an angle α are mounted on the underside of the plate. Hence as the carriage travels towards the hooks of transport means 4a the tension in the threads 5 causes the point at which the orientation of each thread changes from vertical to horizontal to lie on a line 8 parallel to transport means 4a.

A fibrous mat has a sequence of warp knitted stitches extending in a walewise and coursewise direction knitted through it so as to produce a pattern effect caused by the protrusion of the fibres from the composite fabric at positions extending between the stitches. The effect is prominent on both sides of the fabric, the knitted loops appearing on one face and the connecting loops between the stitches occurring on the other side. The pattern effect may be caused by the warp knitted structure being of a tricot stitch or other formation in which knitting occurs on needle groups over a series of wales and courses, the grouping of the needles being rearranged after each series of courses. The relief pattern can be made more conspicuous by using in the basic layer at least two sub-layers made from materials of different potential ...

To produce a nonwoven with a velvet pile surface character, a nonwoven is used which is mostly in a longitudinal orientation containing at least 5 mass% of fusible fibers which melt at a significantly low temperature. To produce a nonwoven with a velvet pile surface character, a nonwoven is used which is mostly in a longitudinal orientation containing at least 5 mass% of fusible fibers which melt at a significantly low temperature. The nonwoven is folded in zigzags to give a serpentine structure (11), and the facing legs of the zigzags are bonded together by their fibers. The bonded package is heated, to melt the fusible fibers at the butting legs of the serpentine material. The bonded package is cut through the center by a conventional pile cutter (F), to be separated into two layers (110,110') each with a velvet pile surface appearance. The nonwoven is folded into a zigzag and the surfaces of the facing legs are bonded together by a row of slide needles for each material surface, to form fiber locking stitches. Each row of needles has knocking-over and controlled holding-down units. A laterally-oriented nonwoven and/or a material with a high content of bicomponent fibers is fed into the knocking-over plane, for its fibers to be looped with the fibers of the nonwoven in the serpentine stack. The nonwoven is laid into folds (A) by a folding roller and a pair of take-in rollers near its circumference. A low-strength pulsed air stream is directed from below the plane of the nonwoven (1) at the surface of the folding roller. After the folding stage (A), the serpentine fabric (11) is compressed within a channel, defined at both sides across the zigzag folds, and the compressed legs of the fabric folds are fixed by heat through heat radiation and/or hot contact surfaces. Directly after the folding (A) and compression (B) stages, the longitudinally oriented nonwoven is initially heat bonded (C) at both surfaces. The bonded surfaces are rubbed to release surface fibers ...

Weft insertion drapery fabrics

WEFT INSERTION DRAPERY FABRICS ABSTRACT OF THE DISCLOSURE An aesthetic dimensionally stable fabric suitable for use as drapery and upholstery fabric, or like decorative fabrics, is produced utilizing a weft inserted warp knitting machine having three or more stitching bars. A substrate that is dimensionally stable warp-wise (such as a 100 percent polyester non-woven fabric that is dimensionally stable both warp-wise and weft-wise) is fed to the machine, as are weft yarns. The weft yarns are stitched in place by stitching thread fed to the stitching bars, the two main stitching bars moving in opposite directions in a basically zigzag form to create an aesthetically pleasing effect, but forming a pattern which is not dimensionally stable. However the final fabric produced is dimensionally stable as a result of the substrate properties. The intermediate fabric has selvage areas. Stitching thread is fed to a third stitching bar which is utilized to provide a dimensionally stable stitching pattern in the selvage areas of the fabric to facilitate finishing operations on the fabric, and the zig-zag form is preferably also continued into the selvage areas by one of the two main stitching bars. The selvage may subsequently be removed. The decorative fabric produced may be foam backed, particularly for drapery use.

Process to and assembly to convert a non-spun pure metal fleece to loops by synchronised use of top and bottom compound needles and plates

A process converts a non-spun pure metal fleece to loops using compound needles. In the process the compound needle shaft (1/) penetrates the fleece from above, while simultaneously an adjacent compound needle (1/2) rises from below. During the reverse action, an adjacent plate (7) deflects the resulting loops into the hooks. The plate movement (7) is synchronised with that of the needles, actively determining the quantity of material lifted from the open needle hooks (1/2). The fibre loops are formed jointly by the action of the plates and compound needle shafts. Also claimed are an assembly to manufacture the metal fibre loops and a commensurate metal fibre fleece.
