Title: Improvements in or relating to the manufacture of a chenille preliminary fabric withchenille warp threads dyed in conformity with the pattern for the weaving of axminster carpets
IPC: D03D39/00
Filed: 1922-02-14
Abstract: 175,630. Vogtlandische Maschinenfabrik vorm. I. C. & H. Dietrich Akt.- Ges., and Liebender, G. Feb. 14, 1921, [Convention date]. Chenille.-In preparing the " ante-carpet," which is cut up into strips that are folded &c. to form chenille threads for weaving "Axminster carpets," the carpet pattern 1, Fig. 1, is passed over a cylinder 2, and two rulers 6, 7 are adjusted by a screw 5 to leave a slot 8 corresponding to the thickness of a chenille thread. A slide 10, provided with a magnifying- glass 12, a pointer 13, and a lamp for illuminating the strip of the pattern 1 visible through the slot 8, is moved across the machine step by step by means of an intermittently - rotated threaded spindle 16. The ruler 7 is provided with a slide 14 bearing the colours present upon the pattern and also marks or signs appropriate for the various colours. The slide is provided with contacts 15 corresponding to the colours on the pattern, and with colours and signs &c. corresponding to those on the slide 14, and that contact is depressed which corresponds to the colour at the time just visible through the slot 8..An electric circuit is thus closed, a magnet 20, Fig. 2, of a card-punching device is excited, and an armature 21 is attracted and enters a recess 22 in a bolt 23, which is thereby coupled to the punch-head 24, so that a hole is punched at 26 into the " card " 27 when the punching-table 25 is raised. When the slide arrives at the edge of the pattern 1, the cylinder 2 is turned a distance corresponding to the thickness of a thread, and the procedure is repeated until the whole of the pattern 1 has been mechanically subdivided into coloured rectangles. The rotation of the spindle 16 may be governed by a " pawl-lever " 19 operated by an electromagnet 28. The "card" 27 thus punched is used to control the successive positions of a magazine comprising a flat plate 31, Fig. 3, provided with sockets 32 for respective coloured weft threads. Threads of different colours, in accordance with the carpet to be subsequently woven, are thereby placed, in succession, in position to be engaged by the threadgripping slides 35 of a weft-inserter 34, which is inserted between the sets of warp threads 33. The slides 35 are operated by two interconnected bellcrank levers 37. When the weft-inserter moves to the right, a lug 39 on one of the levers 37 engages an abutment 40, whereby the slides are opened to receive the weft-thread end, whilst the slides are closed to grip the thread by means of a spring 38. After the gripped thread has been drawn through the shed, it is severed by cutting- blades 43, and is released from the slides by means of an abutment 41, which acts on a lug 42 on one of the bell-crank levers 37. The electrical punching-device may be replaced by a mechanical one.
