  • Patent number: 4147187
    Abstract: A weft thread carrier is disclosed for a loom with a weft thread supply at each side thereof and wherein the carrier, just before entering the shed, engages a weft thread segment that it draws into a loop while moving in the shed. Each weft thread segment extends across the carrier path obliquely to that path, from its supply through a fixed thread eye to the selvedge. The carrier has a hook projecting towards each of its ends, each capable of catching a weft thread segment, but it also has a deflecting surface for each hook, so arranged in relation to its hook that it deflects a thread segment away from the hook if the segment is at one oblique angle to the carrier path but permits the hook to engage a segment at the opposite oblique angle. Hence, as the carrier emerges from each side of the shed it merely deflects the thread segment across its path, but in moving towards the shed its then-forward hook engages the same segment.

  • Patent number: 4073450
    Abstract: A transport device is provided which is driven by an electromotor and on which more than two bobbin supports are mounted and are movable in common such that the respective bobbin to be unwound can be brought into the required association with respect to a stationary thread eye. A thread scanning device is provided adjacent the unwound thread for detecting the thread as it jumps from the bobbin just emptied to the next bobbin. This thread scanning device is connected with the electromotor such that, when the thread scanning device responds, the motor moves the transport device to such an extent that the next bobbin is brought into the required association with respect to the stationary thread eye.

  • Patent number: 3952554
    Abstract: A control device for a textile machine, in particular for a knitting machine having at least one yarn feeding device, with each yarn feeding device being provided with two stop-motion devices each respectively having an electrical stop-motion switch associated therewith. The stop-motion switches of the yarn feeding device are connected to a rectifier circuit such that the two stop-motion switches of the yarn feeding device are supplied with voltage half-waves of different polarity. A control unit is provided which is common to all stop-motion switches and which is capable of surpressing voltage half-waves of one polarity in order to neutralize the stop-motion switch supplied with the voltage halfwaves of said one polarity with reference to a relay which stops the mechanical drive of the textile machine.
