Abstract:
The subject of the invention is a reed for looms comprising at least one rake part (5a, 5b) which, when coupled with a complementary part (5b, 5a), forms a reed (5) having a series of slits (13), extending along the entire height of said reed, and a series of central eyes (12). The reed preferably consists of two similar complementary parts (5a, 5b) each of which has a series of teeth (10) provided with a central slot (11) extending almost halfway along the tooth and ending in a circular eye (12). The reed (5) can be mounted fast onto a loom and so act as a heddle, provision being made on the loom for a movable element (6), with at least two degrees of freedom, on which the warp is set up.
Abstract:
Die Erfindung betrifft ein Transport- oder Antriebsband (1) mit in Längsrichtung verlaufenden Kettfäden (2) und zwischen den Seitenrändern (3, 4) verlaufenden Schussfäden (5). Die Schussfäden (5) sind in der Haupterstreckungsebene des Transportbandes (1) angeordnet und folgen einem gewellten Verlauf, sodass sich zumindest abschnittsweise abweichend von einer zu den Kettfäden (2) rechtwinkligen Geraden abschnittsweise eine positive Steigung (α) in Bewegungsrichtung (6) und eine negative Steigung (β) entgegen der Bewegungsrichtung (6) ergibt. Dadurch trifft bei der Bewegung des Transportbandes (1) der jeweilige Schussfaden (5) nicht über seine gesamte Breite (b) zeitgleich auf die Auflage (7), sondern zeitlich verzögert bezogen auf unterschiedliche Bereiche (8, 9) als Breitenabschnitte des Transportbandes (1). Durch den gewellten Verlauf der Schussfäden (5) wird das in einem Zwickel eingeschlossene Luftvolumen seitlich zu der Auflage (7) verdrängt und entweicht somit kontinuierlich, sodass eine periodische Schwingungsanregung und damit die Geräuschentwicklung auf diese Weise wirkungsvoll vermindert werden kann.
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:
The machine (1) for making fabrics comprising yarns decorated with pearls (15) comprises a yarn holder (2) for feeding a warp yam (3) to a weaving group (5) by aligning all of them onto the same plane by means of cords (7) controlling the feeding direction of the warp (3). The weaving group (5) comprises a reed (9) therethrough the warp yarns (3) pass and cooperating with a bar (11) for forming the fabric (8). The weaving cloth (5) comprises two pincers (13) suitable for inserting a weft yarn between the warp yarns (3). The bar (11) has an indentation (16) faced towards the reed (9) and placed at the passing area of the warp (14). The pincers (13) have a first jaw (18) faced towards a second jaw (19) with substantially triangular profile. The invention also relates to the fabric made with such machine.
Abstract:
An oblong connecting strip (14) is provided to secure a weaving reed (1) to the batten 12) of a mechanical loom. The connecting strip runs in a substantially longitudinal direction (A) of said weaving reed (1) and is connected to the upper profiled section (4) of the weaving reed (1) in addition to being connected to the batten (12) at a distance from the weaving reed (1) in order to reduce the movement of the weaving reed (1) in a longitudinal direction (A).
Abstract:
A power weaving loom has a shed (6) made of warp threads (6) in which a reed (14) is guided back and forth. Weft thread insertion means (26), for example shaped as an insertion band (28) guided on guiding elements (24) linked to a reed lever (23) of the reed (14), are used to insert the weft thread. The guiding elements (24) are coplanar to the mid-plane of a corresponding reed tooth (18a), said mid-plane extending in the direction of motion of a reed tooth (18a). A deflecting member (36) that extends on both sides of the mid-plane in the direction of the weft thread for reliably guiding a warp thread past the guiding element (24) and avoiding interlocking is arranged between the reed tooth (36) and the guiding element (24). Parallel yarns may thus be used in such a power weaving loom even in a high performance range.
Abstract:
Sheet-shaped dents which are made of stainless steel and are adapted for a reed in a high-speed weaving machine. Dents (1A) can be considerably enhanced in durability by having only a surface of that ridge edge portion (3b) of a base material (3), which is in sliding contact with a thread, covered with a hard carbon film (2), and the dents (1A) can be greatly improved in productivity as compared with prior dents which are covered with a hard carbon film. The dents can be efficiently manufactured by laminating a multiplicity of the base materials (3) for sheet-shaped dents, which base materials are formed from stainless steel to have the same shape, with planar surface portions (3a) of the base materials (3) in close contact with one another, placing the base materials in a film forming atmosphere while ridge edge portions not in sliding contact with a thread are caused to abut against a film forming tool and are held in alignment, and covering surfaces of the edge portions (3b) of the respective base material (3), which are in sliding contact with a thread exposed to the film forming atmosphere, with a hard carbon film.
Abstract:
A weft inserting device in a jet loom for preventing flying troubles while keeping the flying speed of a weft at high speed. The device has a reed provided with a plurality of dents (3A, 3B, 9A, 9B) in which guide holes (4, 5, 14, 15) are recessedly provided in the front thereof. At least one wall surface (4b, 5b, 14e, 14g, 15e) for guiding air flowing through a weft inserting path (S) is provided in a wall portion of the respective guide holes of the dents. An inclination angle of the wall surface (4b, 14e, 14g, etc.) provided in a guide hole wall portion of dents disposed in a first section (L1) located at positions closer to a main nozzle of a row of the dents (3A, 9A) is set so as to suppress air leakage to the side of an opening of the weft inserting path. An inclination angle of the wall surface (5b, 15e, etc.) provided in a guide hole wall portion of the dents (3B, 9B) disposed in a second section (L2) positioned on the side opposite to the main nozzle of the row of the dents is set so as to gather air to the center of the weft inserting path.
Abstract:
There is disclosed a method of producing a woven elongate flexible tube (1) suitable for use in producing an inflatable safety belt (1) The method involving providing a plurality of yarns including at least one weft yarn (8) and a plurality of warp yarns (7), said plurality of warp yarns (7) including at least a first set of warp yarns (7a) and a second set of warp yarns (7b), wherein the warp yarns (7a) of said first set have a higher linear mass density than the warp yarns (7b) of said second set. The method furthermore involves simultaneously weaving a pair of plies (2,3) from said yarns (7, 8) in superimposed relation to one another and such that the plies (2,3) become interwoven and interconnected by a pair of transversely s paced - apart and substantially longitudinally-extending woven seams (4) between which said tube (1) is defined. Each ply (2,3) is woven from at least one said weft yarn (8) and a plurality of said warp yarns (7) drawn from both said first set (7a) and said second set (7b); and the weaving process involves: i) using warp yams drawn solely from said first set (7a) to weave a central tensile load-bearing region (6) of each said ply (2,3), located between said seams (4); and ii) using warp yarns drawn solely from said second set (7b) to weave side regions (5) of each said ply (2,3) located on opposite sides of said tensile load-bearing region (6). A shedding process is used in which warp yarns of the first set (7a) are shed via a first shedding mechanism (25), and warp yarns of the second set (7b) are shed via a second shedding mechanism (26), the second mechanism being a Jacquard mechanism In some embodiments the first shedding mechanism (25) may be a Dobby mechanism.
