Abstract: There are disclosed a method of and an apparatus for controlling weft threads, particularly in jet weaving machines with alternating insertion of two different wefts into a shed. At least during the inserting time of the first weft the end of the second weft inserted into the shed before said first weft is held and tensioned and is cut upon finishing the inserting operation of said first weft.The apparatus for controlling wefts includes a pair of inserting jets and weft directing means with guides for each of the weft threads, weft traps being provided between the appurtenant nozzle and the weft directing means, for the purpose of trapping the appurtenant weft in the non-inserting position of the appurtenant inserting nozzle.

Abstract: There is disclosed a device for cutting weft in looms with mechanisms for multi-weft weaving. The cutting device includes a holder on which mutually adjustable shields are mounted. The shields are provided with entrapping dents for the introduction and location of weft between the blades of cutting jaws at a cutting point. The cutting device has a movable jaw which is adjustably connected to a control lever. Adjustable shields and cutting jaws permit the use of the entire length of knife blades secured to the jaws. In this manner, during cutting the overlap is minimized and the lifetimes of the cutting edges and the cutting jaws are increased.

Abstract: A constant tension regulator for controlling the tension of positively unwound flexible material, particularly warp threads in a weaving machine. Means are operatively mounted on the frame of the regulator for sensing changes in tension in the unwinding flexible material. These sensing means output a control movement in accordance with sensed tension in the unwinding flexible material which is translated to a mechanical integrating unit and a proportional adjusting unit, arranged in parallel, which jointly transmit a control variable adjustment to the driving means of the warp beam thereby adjusting its rotary speed in accordance with the sensed tension.

Abstract: A device for supporting the slay drive of a loom such device is especially advantageous in a high-speed loom with a great working width. Two transmission mechanisms are used, these being placed between the loom sides. The device has a housing assembly including a box having a center part, to both ends of which there are affixed gear boxes; to the opposite sides of the center part there are secured exchangeable terminal parts of the said box, the terminal parts being fixed to the sides of the loom. A main shaft is journalled in one of the terminal parts, in the adjacent gear box and in a portion of the center part, the main shaft being connected with a driven shaft in the center part by means of gears. The transmission mechanisms are mounted in the gear boxes, the transmission mechanisms being connected to a cross bar bearing swords upon which the slay is mounted.
