Abstract

<PICT:0486606/IV/1> In the manufacture of artificial threads, and the like, by extrusion, the premature coagulation inside the spinning jet of the liquid being extruded and the consequent blocking of the jet is prevented by providing loosely inserted apparatus in the interior of the cylindrical jet for causing the liquid being extruded to sweep across the interior face of the jet prior to extrusion. Such apparatus consists of a piece of metal or other resistant material, the crosssectional area of which is less than that of the interior of the jet by at least the total area of the holes, and which is spaced apart from the face of the jet by a distance which is small compared with the length of the jet. In the Figure, the insert 4 is cylindrical with a central passage 5 through which liquid is forced. The annular projecting portion 7 spaces the insert from the jet face 3 in which are a number of holes 2.
