Monolithic shed holding component for series shed weaving rotor

Series shed weaving machine with a weaving rotor

A warp guiding device which includes a holding device for mounting a number of warp guide bars (23) and driving devices (24) for moving the warp guide bars is integrally constructed so that it can be brought into and out of operational connection with a weaving rotor of a series-shed weaving machine. The weaving machine includes an installation arrangement for receiving and securing the warp guiding device on the weaving machine.

Warp guiding device module for a series-shed weaving machine

A series-shed loom with a weaving rotor (1) and laying-in members (2) which lay the warp threads (3) into high points and low points on the weaving rotor (1) to form the sheds, while the weaving rotor combs through the sheds (6) so formed to beat-up against a beater bar (8) of a meanwhile inserted weft yarn (7). Warp threads (3a, 3b) are laid into gaps (11) in the combs, while the low points (5) of one warp thread (3) are formed in gaps (11) which are in line in the direction of rotation (9). The high points (4) for one warp thread (3a, 3b) are formed by fins (12) which are in line in the direction of rotation and which form longitudinal saddles (13a, 13b) extending in the direction of rotation (9) between a beater nose (14) and a holder nose (15). To facilitate an interference-free laying in of two warp threads (3a, 3b) in one gap (11), the fin adjoining them on their left is assigned to the left-hand warp thread, and the fin adjoining them on their right is assigned to the right-hand warp thread for possible high points (4).

Weaving rotor comb fin design for series-shed loom

The traversing shed loom has a shedding weaving rotor into which weft yarns are picked. The rotor has shedding elements and beating-up combs in which warp placing guides place warn yarns by moving transversely to the direction of rotor rotation. Most of the warp yarns are deflected transversely to the direction of rotation during shedding and the deflection is cancelled only by the shedding elements moving away before the beating-up of the weft so that the warp yarns are realigned. The beating-up combs have at least two warp yarns per occupied space. The position of guides, the geometry and position of the combs, the position of top shed guides and bottom shed guides and the warp yarn placing program are so adapted to one another that the streakiness, i.e., warp streakiness, is controllable.

Traversing shed loom with warp placing guides

An air jet loom is provided with a brake for braking a weft yarn and a set of deflectors at least one of which is movable in a controlled manner to impart tension in the weft yarn. The movement of the movable deflector can be controlled to reduce the amount of deflection during a braking operation to reduce stress peaks in the weft yarn. The movable deflector may be controlled by a spring, an electromagnet and/or a pneumatic reciprocating actuator.
