  • Patent number: 5794319
    Abstract: A method and a device for drawing warp threads into harness elements of a weaving machine through use of a drawing-in member which effects a reciprocating movement and with at least one conveying device for harness elements. In order to increase the capacity of devices of this type, the drawing-in member is constructed to carry out a reciprocating movement which is short compared with the length of the warp threads. This is done by providing a transporting device that transports the warp thread to a point in front of a weaving reed.

  • Patent number: 5514234
    Abstract: At their free ends the yarns are straightened, clamped and welded with a film. Welding is performed with two welding bars to which is allocated a brush beam to tension the yarns. The welding bars are borne and/or guided by a frame to which the brush beam is also secured. The frame is fitted on a mobile chassis which also has a holder to take a roll of welding film. For use in weaving preparation works and in weaving works, especially in preparing the warp and in starting weaving.

  • Patent number: 5475906
    Abstract: The separating apparatus contains carrier rails for the storage of healds in the form of a stack, a dividing-off member for pushing the foremost heald laterally out of the stack into an intermediate position, and a first transfer device for transporting the healds from the intermediate position in the direction of a heald carrier for transporting the healds to their drawing-in position. Provided in the region between the intermediate position and the heald carrier is a lock which contains a controlled clamp for clamping the carrier rails. The lock is briefly opened for transporting a separated heald past the lock to the heald carrier. The apparatus can be used to separate healds of all types, especially of those having closed end loops.

  • Patent number: 5459913
    Abstract: The heald handling apparatus contains carrier rails for the storage of the healds and a transport device for feeding the healds to a separating station. Each carrier rail is held by a plurality of controlled clamps and is thereby subdivided into a plurality of sections, each for receiving a heald set. The transport of the healds takes place in sets from section to section, the clamp located between the respective sections being opened. The control of the clamps takes place by means of sensors assigned to the clamps, at least one sensor being provided for each pair of clamps belonging together. The heald handling apparatus can be used in connection with healds having closed end loops and healds having open end loops.
