Definitions
- the invention relates to a device for forming a leno selvedge consisting of mutually moving heald frames, a needle holder being attached to one heald frame and a thread guide device being attached to the other heald frame, and the needle holder having two parallel frame rails having a thread guide element that is movable and braked relative to the thread guide device.
- the invention is therefore based on the object to change the device of the type mentioned so that the wear of both the thread guide element and the frame rails is reduced.
- the surface pressure of the thread guide element on the frame rails is reduced, so that there is a reduction in wear.
- a further reduction in wear is achieved in particular in that the thread guide element has magnets in the region of the enlarged sliding surface, the magnets being embedded in the sliding surface in such a way that the upper edge of the magnets lies lower than the sliding surface.
- the thread guide element known from the prior art has the tendency to tilt due to the arrangement of the magnets and the magnetic forces that occur. This inclination is counteracted by the arrangement of the magnets on only one side of the thread guide element, so that the thread guide element now has the endeavor to lie flat on the respective frame rail.
- the opposite frame rail only serves to guide the thread guide element to the front and back; touching the sliding edge of this frame rail by the thread guide element is virtually impossible. Should a frame rail wear out despite the special design of the thread guide element, it is possible to use a new thread guide element so that its sliding surface now lies against the frame rail, which is not yet worn.
- the thread guide device consists of a carrier for receiving a second thread guide element, driving elements being arranged on both sides at a distance from the thread guide element on the carrier, which in the assembled state of the needle holder and carrier are in the two parallel frame rails of the needle holder protrude into the formed space. This causes the relative movement of the thread guide element arranged in the frame rails to the second thread guide element arranged in the carrier.
- the ends of the sliding surface of the thread guide element guided in the frame rails are chamfered. It is hereby avoided that the driving elements run against the front edge of the sliding surface.
- the sliding surface In order to further ensure that the sliding surface is always in the area of the carrier elements of the carrier, the sliding surface has a length which corresponds approximately to the distance between the two carrier elements to one another plus their length.
- the device for forming a leno selvedge consists of reciprocally moving heald frames 1 and 1a, a needle holder designated by 2 being arranged on one heald frame 1.
- the other heald frame 1a shows a thread guide device, denoted overall by 3.
- the needle holder 2 has two parallel frame rails 4 and 5, which serve to receive and guide the thread guide element 6 (Fig. 1).
- the thread guide device 3 arranged on the heald frame 1a consists of a carrier 7 which receives the second thread guide element 8.
- the carrier 7 has driver elements 9 and 10 on both sides of the thread guide element 8. These entrainment elements protrude into the space formed by the two parallel frame rails 4 and 5 of the needle holder and bring about the relative movement of the thread guide element 6 to the needle holder 2.
- the entrainment elements 9 and 10 are connected to the carrier 7 by elastic pins 11 and 12, and slide during of operation along the outer edges of the frame rails 4, 5.
- the thread guide element 6 consists of a carrier part, designated 13, which receives the thread guide part 14 made of ceramic.
- the carrier part 13 for the thread guide part has the enlarged sliding surface 15, into which the magnets 16 are embedded in the area of the ceramic thread guide part 14.
- the sliding surface 15 of the thread guide element can optionally bear against one guide rail 4 or the other guide rail 5.
- the length of the sliding surface 15 of the thread guide element 6 corresponds approximately to the distance between the two entrainment elements 9 and 10 arranged on the carrier 7 plus their length, which is designated by X in FIG. 1.
- the length of the sliding surface is so chosen that it is always in the area of the driving elements 9 and 10 during the lifting movement.
- the sliding surface is bevelled at the end at 17.
