  • Patent number: 4436123
    Abstract: 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.

  • Patent number: 4432399
    Abstract: A filling-thread monitoring device for jet looms in which a filling thread is guided during its introduction into the shed of a loom in a first guide channel which is formed by spaced members and is partially open on its side, contains a first filling thread stop motion means for the giving off of a signal when the filling thread introduced does not reach its normal length and a second filling thread stop motion means spaced from the first stop motion means in order to give off a signal when the filling thread introduced exceeds its normal length by a predetermined amount. Between the two filling thread stop motion means, a guide member is arranged which extends over the space which is free of warp threads and has a second guide channel which lies in the extension of the first guide channel and is closed in the filling direction.

  • Patent number: 4407336
    Abstract: There is disclosed a thread-feed device having a stationary winder drum storing a supply of thread which can be wound-on by means of a rotatable winder arm and removed overhead from the winder drum, and having a first monitoring device which automatically controls the rotary movement of the winder arm as a function of the length of the supply of thread formed. Within the region of the withdrawal end of the winder drum there is arranged a second monitoring device which gives off a first signal to a control unit upon each pass of the thread through its monitoring region during the withdrawal of the thread. The control unit counts the first signals and, as soon as their number reaches a predetermined adjustable value which corresponds to the desired required length of thread, there is given off a second signal by which a thread gripper is actuated so that the thread-feed device delivers precisely measured lengths of thread, such as required for instance for the filling insertion on jet looms.
