Abstract

1390897 Chenille yarn FILCOR SL 3 July 1973 [4 July 1972] 31639/73 Headings DID D1F and D1W A machine for the manufacture of chenille yarns comprises means 195 for supplying at least two first core threads 177 from bobbins 178 maintained stationary relative to the machine, means for winding chenille effect thread 25 around the core threads 177 while guiding the thread 25 from a creel- 22 to form a balloon 199 of rotating thread around the bobbins 178, means for supplying external second core threads 18 laterally of the woundon chenille effect thread 25, means for cutting the turns of effect thread 25 between pairs or groups comprising one fish core thread 177 and one second core thread 18, and means for twisting and winding the at least two chenille yarns so formed. The core threads 177 are passed down stationary guide spindle 151, maintained stationary by permanent magnets 173, 175 or by being otherwise fixed to a machine part. The spindle 151 passes through a further spindle 28 which is mounted for rotation relative to the spindle 151 by bearings 150. Conduits 144 are provided in the spindle 28 for the passage of effect thread 25. Mounted within the end of the spindle 151 there is provided a mandrel 160 in the form of a plate, the core threads 177 passing on either side of the plate. The effect thread 25 passes from conduits 144 through conduit 165 in end cap 164 and is wound around the core threads 177 and mandrel 160. The effect thread 25 is led to the conduit 144 via a rotating guide 149 whereby a balloon 199 is formed about the bobbin 178; balloon guards 176a and 139 are preferably provided. The second core threads 18 are fed from bobbin 17 via guides 200 to endless belts 250 which are guided to run parallel to the mandrel 160. One or more rotating circular knives are inserted in a slot provided in the end of the mandrel 160 whereby the turns of effect thread are severed. The severed effect thread pieces are entrained between one core thread 177 and one core thread 18 and conveyed to the twisting means e.g. a ring twister 201. The drive mechanisms for the various machine parts are fully described together with yarn absence indicators and warning lamp 271 when the machine is stopped due to yarn absence. With reference to the ring twister 201, a mechanism is described for shortening the traverse of the ring rail to produce a tapered package.
