摘要:
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).

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.

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.

A weft end recovery apparatus comprises weft end carrier for carrying by water flow weft ends formed as a result of weft insertion, a plurality of storing and dewatering sections to receive the weft ends carried from the weft end carrier together with the water, and switching mechanism for selectively switching the storing and dewatering sections to store the weft ends and the water from the weft end carrier.

Apparatus for depositing a substance on threads (2, 3, 4; 25; 50, 51, 52) in a textile machine is designed in a way such that the substance is deposited in pulses the frequency and/or amplitudes of which are controlled as a function of the speed and/or tension of moving threads (2, 3, 4).
摘要:
An equipment for transporting, handling and feeding stock bobbins to a loom having a preparation station (5) for the charging of bobbin holders (12) with stock bobbins (4) and a transport loop (7) for transporting these bobbin holders (12) towards looms. The looms are arranged in groups and for returning bobbin holders (12') containing empty bobbin tubes towards the preparation station (5), as well as at least one storage section (7c) branching off the transport loop (7) for receiving a number of the bobbin holders (12, 12') which corresponds with the need of bobbins at the time by at least one of the groups of looms (1a, 1b, . . . 1n). For the exchange of the bobbin holders (12' or 12 respectively) on the looms a loading mechanism (18) is provided which is mounted on a secondary transport mechanism (10) which may be moved independently of the transport loop (7) towards a number of groups of looms (1a, 1b, . . . 1n) and is intended for temporarily receiving the bobbin holders (12, 12') which may be fed from and returned to the storage section (7c). Through this execution a simple clearly arranged method of construction of the equipment is achieved, which makes possible a loading of the looms with stock bobbins to match the needs, which may be automated in a simple manner.
