A gripper head of a weaving machine has a clamping device for clamping a band-shaped weft material to be inserted into a loom shed of the weaving machine. The clamping device includes a stationary clamping jaw and a movable clamping jaw that is loaded by a spring and movable about a rotation axis. Each clamping jaw respectively has a clamping surface. The movable clamping jaw is actuatable by a control device to open the clamping device. The gripper head includes a frame, and the clamping surfaces are arranged essentially outside of the frame, but the spring and the rotation axis are arranged inside the frame.

The machine (1) for making fabrics comprising yarns decorated with pearls (15) comprises a yarn holder (2) for feeding a warp yarn (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.

An apparatus (1) is presented for the insertion of a weft thread (2) into a shed (10) of a rapier weaving machine. The apparatus (1) includes a rapier tape (3b) movable in the insertion direction, a rapier head (3a) at the same and at least one guide part (5) which is provided at the rapier tape or at the rapier head as well as a plurality of guide elements (6.1-6.i+1) which cooperate with the guide part to guide the rapier tape or the rapier head in the shed, wherein the start of the guidance of the guide part by the guide elements is delayed until the rapier tip ( 3) is at a distance of at least 14 cm in the shed.

Device for locking the connection of a heddle (40) to a harness cord (50), having a heddle side and a harness cord side. The device is composed of at most two different components, the device having a diameter on the heddle side and/or on the harness cord side which decreases towards the end. The device is releasable and recloseable, allowing the device to be reused. The components are made from a plastics material which has a high wear resistance. The device is provided over virtually its entire length with a continuous passage (4) for guiding a heddle and a harness cord.

A Clamp for a rapier loom having A hollow body with first and second ends. The first end is adapted to be fastened to a transporting tape of the rapier loom. A thread gripping hook is mounted on the second end of the hollow body. A movable element is mounted in the hollow body and movable between retracted and extended positions. A tongue has first and second ends. The first end is mounted on the hollow body and the second end is adjacent the gripping hook. The second end is separate from the hook when the moving element is in the retracted position, and in contact with the hook when the moving element is in the extended position. A resultant movement of the tongue is in a direction substantially perpendicular to a path of the movable element.

A controlled weft thread presenting and clamping arrangement minimizes weft thread waste and ensures proper tensioning of the weft thread during its presentation to the insertion gripper, in a gripper loom for weaving with plural different weft threads. The arrangement includes a control shaft (13) that has a drive key (14) protruding therefrom in a reference plane (7), and that is rotatably supported on a support bracket (10, 11, 12), which may be mounted on the loom. Weft thread presenting levers (15) each carrying a respective clamp (16) are movably arranged on the shaft (13), which passes through a hole in each of the presenting levers (15). A translational drive (22) acts on a presenting lever support (17) to translationally move all of the presenting levers (15) in unison together axially along the shaft (13) until a selected lever (15) is positioned in the reference plane (7), with the lever's drive groove 15B engaged on the drive key (14) of the shaft (13). A rotational drive (23) rotates the shaft (13), and therewith the selected thread presenting lever (15) via the drive key (14). A guide member (19) has a lengthwise groove (20) to allow all of the presenting levers (15) to move linearly therealong in unison, and a crosswise groove (21) in the reference plane (7) to allow only the selected presenting lever (15) to rotate in the reference plane. A thread back tensioning device (9) is arranged in the thread path to apply tension to the thread being presented to the gripper.
摘要:
An weft yarn gripping device in a shuttleless loom in which the spring-loaded lever for pressing the gripping foot onto the relative rigid gripping surface cooperates with a travel stop block which absorbs part of the load exerted by said spring. The block is connected to the foot by a leaf spring rigid with the lever, and the leaf spring is inserted into a slot in a connection block which is rigid with said foot. Various mechanisms are also provided for varying the load transmitted to the gripping foot.
摘要:
A weft thread inserting gripper for a loom is equipped with a guide element attached to a side wall of the gripper. In order to enable the guide element to properly contact the reed when the gripper moves in the loom shed, the guide element and gripper combination is so constructed that at least the guide element can tilt about a journal axis extending in parallel to the direction of gripper movement. This tilting ability can be achieved by mounting the guide element itself to a gripper side wall for pivoting about the journal axis. The same tilting effect can be achieved by mounting the entire gripper side wall carrying the guide element on such a journal axis. Both possibilities assure an optimal surface contact between the guide element and the respective surface in the loom to provide a quiet and smooth gripper motion.
