Abstract: A device for removing a thread includes a rotatable ring and a rotatable boom. THe rotatable boom is displaceable toward the rotatable ring to clamp an end of the thread between the inner surface of the rotatable ring and the outer surface of the rotatable boom. The device also includes a driver for (1) displacing the rotatable boom toward the rotatable ring to clamp the end of the thread between the inner surface of the rotatable ring and the outer surface of the rotatable boom and (2) rotating the rotatable boom while the end of the thread is clamped between the inner surface of the rotatable ring and the outer surface of the rotatable boom.

Abstract: Method of preparing a weft and its removal from an open shed in jet weaving machines automates the preparatory operation of weft upon finding a weaving fault. This is achieved by performing both the preparation and the withdrawal of the weft in the course of the first quadrant of the jet weaving machine revolution. The method includes the step of supplying a further unseparated weft length, forming a loop between the unseparated weft length in the open shed while the loop elongates due to the action of an inserting medium until the loop face emerges from the shed on the shed outlet side and removing the weft from the shed by a weft withdrawing device.

Abstract: Clutch mechanism, particularly for looms. The mechanism has a housing, in which a pair of opposed electromagnets are stationarily mounted, between which there is arranged a friction disc mounted axially displaceably on a driven shaft. A rotor, fixedly connected to a control shaft disposed coaxially of the driven shaft, is disposed between one electromagnet and the friction disc for selective driving engagement therewith.
