Abstract

<PICT:0344351/IV/1> <PICT:0344351/IV/2> <PICT:0344351/IV/3> Artificial threads are produced by extruding a spinning solution through a jet having a plurality of groups of spinning orifices, the filaments from each group of orifices being collected as a separate thread. The threads may be collected on separate winding or twisting and winding devices. The filaments may be produced by dry or wet spinning, and may consist of cellulose acetate or other organic derivative of cellulose, or of regenerated cellulose. As shown, two groups of filaments 9, 10 are extruded from a jet 8 having two groups of orifices arranged side by side. The filaments pass round a feed roller 12 outside the cell, and are collected on cap-spinning devices 16, 17, arranged in two rows as described in Specification 343,965. To separate the groups of filaments when the apparatus is started, a dividing plate of the shape shown in Fig. 5 is inserted through a door 13 in the cell; the point of the plate is inserted between the filaments, which are gathered together as two threads in the notches 26. It may be necessary to insert the plate also at points lower down in the cell. The orifices in the jet 8 may be arranged on the circumference of a circle, but Fig. 4 shows an alternative form in which four groups of orifices are arranged on the circumferences of two concentric circles. Reference is made also to the arrangement of the orifices in two or more lines.
