Abstract:
This invention is about easy and effective reed clamping arrangement for weaving machines which consists of two counteracting wedges wherein a vertical clamping force of the fastener of point load type is converted in to a more or less uniformly distributed horizontal clamping force of the wedges on the reed, the wedge strip does not have any holes and hence the breakages of wedges in event of uneven clamping are totally avoided. Further the wedge strips always keep themselves afloat in event of de-clamping and even after removal of reed and no efforts are required to lift the wedge in event of inserting the reed again in the slot. The clamping arrangement is so devised that the clamping force of the fasteners is multiplied and transmitted transversely on the reed making it a highly rigid reed holding arrangement ever.

Abstract:
Different weaving materials, apparatuses, and methods are provided for producing woven textiles having different functional and aesthetic characteristics as compared to woven textiles produced using conventional methods. The different weaving materials comprise reactive materials or combined materials produced by an intermittent splicer. The different apparatuses include finishing devices for introducing organically-shaped lateral edges and interior apertures, and three-dimensional effectors for introducing three-dimensional aspects into a product as it is being woven. Weaving methods include simultaneously weaving fine denier panels and coarse denier panels.
Abstract:
An einer Webmaschine zur Herstellung von Geweben mit Zusatzmustereffekten werden einer oder mehrere im wesentlichen in Kettrichtung zugeführte Effektfäden (2) oberhalb eines einzutragenden Schussfadens (3) für verschiedene Bewegungszyklen der Webmaschine in Schussrichtung (12) über benachbarte Kettfäden (1) hinweg verschoben. Bei der anschließenden Positionierung der Effektfäden (2) unterhalb des einzutragenden Schussfadens (3) tauchen die Effektfäden (2) in einseitig nach oben offene Rietlücken (8) eines Webblattes (4) ein. Um das Eintauchen der Effektfäden (2) in die Rietlücken (8) zu unterstützen, wird ein Webblatt (4) mit einer ersten Gruppe von Webblattzähnen (5) ausgestattet, die an ihrem oberen Ende eine in Längsrichtung des Webblattes (4) weisende Einführschräge (7) aufweisen. Diese sind derartig gestaltet ist, dass dadurch die nach oben weisende Öffnung einer benachbarten Rietlücke (8) zu mindestens teilweise abdeckt ist. Weiterhin ist eine zweite Gruppe von Webblattzähnen (5) am Webblatt (4) vorhanden, die keine derartige Einführschräge (7) aufweisen.
Abstract:
Disclosed is a fixture for the reed of a seam weaving machine used for joining two opposite ends of a synthetic fabric by means of a woven seam. The reed is provided with pivotally mounted combs (22) for sliding seam weft threads to the selvage. The fixture comprises an inclined rail (24) and a pressure rail (30) which are disposed at a distance from the bearing mechanism (20) and apply opposite torques to the combs (22), as well as devices (26, 32) for positioning the inclined rail (24) and the pressure rail (30) at angles relative to the bearing mechanism (20) in order to stagger the combs (22) in the position thereof by means of the inclined rail (24) and the pressure rail (30) so as to operate the machine in a first mode of operation. A roll is also provided which can be displaced along a track across the width of the reed in order to successively swivel the combs (22) towards the selvage so as to operate the machine in a second mode of operation. The inclined rail (24) or the pressure rail (30) can be removed from the combs (22) to operate the machine in the second mode of operation. A U-shaped rail (40) can be placed on the front side of the combs (22) in the second mode of operation, the bottom leg (42) of said U-shaped rail (40) impinging the combs (22) below the shaft (20) and the top leg (44) thereof impinging the combs (22) above the shaft (20).
Abstract:
The present embodiments provide a woven element having a first plurality of warp threads extending in a first direction and integrated into a first surface on a front side of the woven element. The woven element may have a second plurality of warp threads extending in the first direction, where the second plurality of warp threads is integrated into a second surface on a back side of the woven element. A first weft thread may extend in a second direction, where a first portion of the first weft thread is positioned in front of at least one warp thread of the first plurality of warp threads to form at least a portion of a graphic image on the front surface. A second portion of the first weft thread may extend between the first plurality of warp threads and the second plurality of warp threads.
Abstract:
A reed assembly for leno weaving, the reed assembly including upper and lower reed frame members (22, 23) between which a plurality of dent fingers (25) extend, each pair of neighbouring dent fingers (25) being spaced apart to define a dent space (26) for a crossing-over warp yarn (5), a yarn guide finger (27) co-operating with each dent space (26) for guiding a crossed-over warp yarn (5) therethrough, each yarn guide finger (27) extending from one of the frame members (23) and having a terminal end spaced from the other frame member (22) so as to divide the co-operating dent space (26) into a pair of cross-over dent spaces (26a, 26b) extending between said terminal end and said one frame member (23) and being defined between facing sides of the guide finger (27) and the pair of neighbouring dent fingers (25) and a cross-over transfer region extending between said terminal end and said other frame member (22) and being located between opposed faces of the pair of neighbouring dent fingers.
Abstract:
A method of insertion of the weft thread into the shed of an air-operated jet loom in which to the main stream of air supplied to the beginning of the direct pick channel (10) of the swinging loom reed (1) are added at regular length intervals of the direct pick channel (10) ancillary air streams (22) oriented obliquely in the direction of the weft thread insertion into the open side (11) of the direct pick channel (10) through which they carry the weft thread. The ancillary air streams (22) are oriented toward the axis (4) of swinging of the loom reed (1) and comprise a vertical component (23) of force acting on the weft thread in the direction of the force of gravity, thus stabilising the affect ot the air stream on the weft thread due to the fact that the weft thread is fed exclusively (all way through) near the bottom of the direct pick channel (10). The device for carrying out the method comprises ancillary jets (14) and is so arranged that the plane ((tau)) passing through any of the outlet apertures (15, 151, 152, 152A, 152B) and the axis (4) of swinging of the loom reed (1) passes during the weft thread pick also through the open side (11) of the direct pick channel (10) of the loom reed (1).
Abstract:
A diamond-like carbon (DLC) film is spread over the dents of a reeed as a part of a high speed loom at a part of the dents requiring the highest resistance-to-wear. When using stainless steel as a base material of the dents, DLC film is spread through an intermediate layer comprising, for example, a titanium carbide layer. Reed dents covered with a DLC layer are arranged at side ends of the reed which are likely to wear severly and, at the middle portion of the reed, dents covered with comparatively inexpensive hard film or non-treated dents are arranged so that degrees of wear of reed dents may be uniform throughout the reed for enabling reduction in cost. A reed of this invention is applicable to a variety of fibers such as natural fibers, synthetic ones, and new material ones, whereby durability of a reed is markedly increased at low cost.
