DEVICE FOR FEEDING WEFT THREADS TO A GRIPPER HEAD OF A LOOM
20240200241 · 2024-06-20 ·

A device feeds first and second weft threads in a weft direction to a gripper head of a loom and includes a coupling unit that moves back and forth in a warp direction. A first and a second feed unit are adjacently arranged in the warp direction on the coupling unit and are configured to feed the first and the second weft threads to the gripper head. A positioning unit moves the coupling unit in the warp direction in a first position of the coupling unit and counter to the warp direction in a second position of the coupling unit. The first feed unit feeds the first weft thread to the gripper head when the coupling unit is in the first position and the second feed unit feeds the second weft thread to the gripper head when the coupling unit is in the second position.

Weaving Machine with an Apparatus as well as Method for Holding, Feeding and Inserting Weft Threads in a Loom Shed
20180291538 · 2018-10-11 ·

Apparatus and method for holding and feeding weft threads (1, 2) to the gripper (6) of a weaving machine with drives (25, 29), with which clamps (11, 12) for the weft threads (1, 2) are moved on motion paths (35, 36) into respectively a feed position (16, 19), a transfer position (17, 20) and a ready position (18, 21). The motion path (35, 36) of each clamp comprises a shape that is closed in itself. In that regard, the motion beginning of at least one of the clamps (11, 12) out of its ready position (18, 21) into its feed position (16, 19) takes place in a time segment that extends from the beginning of the beat-up motion of the weaving reed (9) until the beat-up of the previously inserted weft thread (1, 2) against the beat-up line (10) of the weaving machine.

MULTI-LAYERED WOVEN ELEMENT
20170198424 · 2017-07-13 · ·

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.

Intermittent Weaving Splicer
20170101732 · 2017-04-13 ·

Woven products using combined materials are provided. An intermittent weaving splicer terminates and combines materials having different functional and/or aesthetic properties to create woven products that reflect the different properties of the combined material. Further, a dynamic tensioner variably adjusts tension on the combined materials based on the different properties of the combined material.
