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

The device for the storing of filamentary material contains a thread storage and a feed nozzle associated with it, the thread storage having a thread carrier which rotates past the feed nozzle and the feed nozzle being arranged fixed in position and rigid; and the depositing of the thread (S.sub.1, S.sub.2, S.sub.3) on the thread carrier takes place in the form of thread packages (P.sub.1, P.sub.2, P.sub.3) which consist of partially superimposed turns so that the length of the thread package (P.sub.1, P.sub.2, P.sub.3) and thus of the entire storage can be kept small, so that the storage is particularly suitable for looms, especially when using so-called mixers. The thread carrier is preferably covered by a small plate at the point of the formation of the thread packages, and the thread packages are deposited in the space between the thread carrier and the plate. In this way the thread packages are fixed on the thread carrier and the individual turns cannot entangle or move relative to each other, so that the device is also excellent for heavy yarn.
