摘要:
The present invention relates to a fabric support for weaving looms, of the type comprising a main body (2) and a lip (1a) for supporting the fabric (T) and apt to co-operate with a template (4) for tensioning the fabric, which is mounted in an adjustable manner on a base element (30) by means of a rotoidal guide (6) which allows adjustment thereof according to a rotational displacement.

There is disclosed a bonded woven fabric product and a method for its manufacture. The product finds use as a tufting substrate for carpet manufacture. Existing problems in the field include deformation of fabric weave in fabric stretched in the fabric plane; deflection of flat rectangular polypropylene tapes giving stitch placement defects within a carpet; and reduced dimensional stability, strength and tuft lock in mechanically fibrillated tapes. The invention provides a woven product (Fid. 1, 5a) comprising a plurality of first threads (10a), and a plurality of second threads (15a), wherein contact portions (20a) provided along each first thread (10a) contact respective contact portions (25a) provided along each second thread (15a), wherein further each first thread (10a) is bonded to each second thread (15a) at the respective contact portions (20a, 25a).

The present invention provides a warp-splicing method that increases the splicing strength between the end and starting parts of warps. A method for splicing the end part 27 of one warp 16 to the starting part 27a of another warp 16a wherein the ends part 27 of the yarns 26 of warp 16 are overlapped with the starting part 27a of the yarn 26a of warp 16a, a twist 31 is applied to the overlapped yarns 26 and 26a of warps 16 and 16a by pinching the yarns by using twist bars 30 and moving them widthwise with respect to each other, and the yarns are bonded together using a bonding agent 35 to splice the yarns 26 and 26a.

The invention relates to a device for changing the harness of a loom. It has two bearing columns (16) arranged on a chassis, two jibs (18) which can move vertically on the columns and horizontally extendible and a device (26) on the jibs (18) to transfer head frames. The head frame transfer device (26) comrpises two spaced boundary plates (32) interconnected by at least one cross-member (28) and fitted with guide rails (30) for the head frames and two spaced bearers (34) on a transverse support (22) connected to the boundary plates (32) and which can pivot in relation to the transverse support (22) to accept and transfer the head frames. In order to adapt the article changer to different weave widths, the distance between the boundary plates (32) can be adjusted by hand or by a motor. To this end, the cross-members (28) and the transvers support (22) consist of two simultaneously actuatable teles copic sections (28', 28''; 22', 22'').

Apparatus for use in mounting and dismounting a warp beam (19), loaded with cannisters of warp thread onto or from a loom comprises a trolley (10), with a hoverpad (18) mounted under the trolley, and with a bracket (20) carrying warp healds and reels. Trolleys may be combined, to carry two beams together, one trolley being arranged at the end of each beam, and the respective end trolleys being connected to the trolley in front of or behind it.
摘要:
Der Erfindung liegt die Aufgabe zugrunde, unabhängig vom Einsprungverhalten der Gewebekanten einer auf Webmaschinen herzustellenden Gewebebahn, eine neben der Gewebekante liegende Schnittkante zu realisieren, die dem Verlauf der Gewebekante entspricht. Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass an einem feststehenden Teil (2;3) der Schneideinrichtung (1) beabstandet von dem Klingenbolzen (6) ein mit der Kante (8a) der Gewebebahn (8) federbelastet in Kontakt stehendes Führungselement (9) zum Führen der Schneideinrichtung (1) angeordnet ist.

According to the invention, on the weaving rotor (2) of a shed course loom there is a cover (22) which, with the weaving rotor (2), in the direction of rotation (20) from an insertion station (6) to the fabric stop (13) forms an annular channel (23) which is closed in the direction of rotation (20) and at the front (33) by further covers (26, 33) on the arrival of the weft. Along the stop edge (13) there are suction nozzles (24) which are so designed that, despite the air entering from the shot and relay nozzles (63), they generate an underpressure and a flow (25) from the insertion station (6) to the stop (13) which prevents the deposition of fly. In addition, a further suction nozzle (34) arranged weft wise at the weft intake stabilises the flow ratios in the annular channel (23).

Die Webmaschine ist eine Kombination einer Projektilwebmaschine, welche einen Schaftantrieb, eine Mehrzahl von Webschäften eine Schusseintragvorrichtung und eine Weblade (8) aufweist mit einem Gestell, welches weitere Funktionsgruppen, z.B. einen Spannbaum (22), eine Kettfadenwächtereinheit usw. umfasst.
摘要:
A method for enhancing the weaving of a warp yarn fabric having a high modulus of elasticity, wherein a sheet of parallel warp yarns (3) is continuously unwound from a beam (1), the sheet is fed over a whip roll (4), a shed (9) is formed using heddles (7, 8), said shed being defined in the forward direction of the warp by a shed opening point (15) on the inlet side and a fell point (10) on the opposite side, a weft yarn is inserted into the shed close to the fell point (10) to form a fabric, and the resulting fabric is evenly pulled and wound. According to the method, the warp yarns (3) are heated in an area adjacent to the shed opening point to a temperature high enough to cause a local reduction in the modulus of elasticity of the warp yarns (plus stretching thereof in the case of thermoplastic yarns), whereafter the warp yarns are cooled in the shed before they reach the heddles (7, 8).
