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.

Filament threads such as rayon threads which may be smooth or partly texturized for protection, are texturized or entangled in the loom just prior to their insertion into a loom shed as weft threads. For this purpose a texturizer (4) is positioned between a filament thread supply spool (1) and a weft thread accumulator (3). The accumulator in turn is positioned just upstream of an air insertion nozzle (11) for injecting the weft threads into a loom shed. The texturizing is sufficient to lock the filaments into the filament thread body so that these texturized filaments form threads that can be pneumatically transported through the loom shed without causing so-called blow-outs of individual filaments out of the weft thread body.

The device comprises a container, closed by a lid, for holding the lubricating fluid; a strip of felt or the like is immersed in the container and becomes impregnated with the fluid by capillary action. One end of the strip protrudes from the lid of the container and wraps around a cylindrical support so that a respective portion of the strip, shaped like a cylindrical sector and impregnated with lubricating fluid, protrudes with respect to the surface of the lid and is exposed. The weft thread to be lubricated is made to slide on the exposed portion of the strip, and means are provided for guiding the thread and for producing a cyclic transverse movement thereof from one end to the other of the exposed portion.

Device intended for extracting weft threads (T) arranged transversely in a straight grain reinforcing ply (F) comprising a hook capable of gripping a weft thread (T) by performing an alternating movement between a high position and a low position, characterized in that the hook engages with a disengageable anvil capable of moving along the path (XX′) of the hook so that when the device is in operation, the anvil is engaged in contact with the hook during all or part of the descending movement of said hook, forming a clamp capable of holding a section of weft between the hook and the anvil the anvil is disengaged from contact with said hook during the remainder of the travel of the hook, so as to enable the hook to engage a weft thread (T) and to release a section of weft (T).

An automatic lacer wraps bundles of polymeric fibers with thread, before the bundles are woven into a fabric mat and placed in a housing to form a gas-separation membrane module. A fiber bundle passes through a spool which is previously wound with thread on its outer surface. The thread is attached to the fiber bundle, so that when the bundle is moved through the spool, the thread is pulled from the spool, and automatically becomes wound around the bundle. Threads from two or more spools may be wrapped around the fiber bundle simultaneously. Lacing of the fiber bundles reduces the amount of tangling in the loom feeder, and improves the quality of modules made from the fiber bundles.

The weft thread or weft threads in an air nozzle loom are plied into multi-strand weft threads directly in the loom. For this purpose one or several plying devices are arranged directly in the loom between a plurality of weft thread strand supply spools or cross-wound bobbins and the multi-ply weft thread insertion nozzle.

The method for storing weft ends in a fluid jet loom is characterized by carrying by a water flow weft ends formed due to weft insertion, discharging the same together with the water flow from a discharge section to a storage section, storing the same, and moving the discharge section during discharging.
摘要:
A yarn processing system which includes a yarn feeding device and an accessory device associated with the yarn feeding device. The accessory device has a device which is driven using a signal representing the rotational speed of a component of the yarn feeding device. The signal is generated by an electronic sensor galvanically separated from the control system and the drive mechanism of the yarn feeding device. The sensor also is structurally independent from the yarn feeding device. The sensor is located at or close to the yarn feeding device at a mounting location where a part of a rotating magnetic field is detected by the sensor at the mounting location. The part of the magnetic field originating from inside of the yarn feeding device is not used for the operation of the yarn feeding device at the mounting location of the sensor.

A yarn-conveying system in the route consisting of a fine spinning process, a rewinding process. A first closed loop is provided between a fine spinning machine and a winder for conveying cops or empty bobbins and a second closed loop is formed between the winder and a weaving machine for conveying packages and empty paper spools.
