Abstract

<PICT:0865843/IV (a)/1> A spinneret or spinneret plate for the meltspinning of hollow synthetic organic thermoplastic polymeric filaments comprises a circular steel body 2 (Figs. 1 to 5) about 2 inches in diameter and about 1/5 th inch thick having a number of evenly spaced annular extrusion orifices 3 (Fig. 1) extending from the inlet face 2a (Figs. 2 and 5) to the exit face 2b thereof. Each extrusion orifice 3 consists of a circular hole 4 (Figs. 1, 2, 3 and 4) extending from the inlet face 2a of the body 2 to a depth somewhat less than half the thickness of the body 2 and having a flat bottom 4a. From this flat bottom 4a extend two smaller counterbored holes 5, which are separated from one another by a thin web-like portion 6 of the body 2. Beneath the holes 5 and extending from the exit face 2b of the body 2 inwardly of the body p to a depth beyond the bottom faces of the holes 5 is an annular opening 7 (Figs. 2, 3 and 4) of such radius that the interior thereof communicates with the interior of each of the holes 5, whereby there is formed an extrusion passageway extending through the thickness of the spinneret plate 2 and comprising the two holes 5 and the annular opening 7 communicating therewith the core 8 of which is an integral portion of the web 6. As shown in Fig. 4, the larger hole 4 may be omitted, the two holes 5 in this case lying flush with the inlet face 2a of the body 2, and the web portion 6 extending to this face. The opening 7 may be of rectangular shape 9 with a rectangular core 6, as shown in Fig. 5. The holes 5 may be non-circular and may have concave or convex instead of flat bottoms. There may be more than two holes 5 communicating with annular (or rectangular) extrusion orifice 7 (or 9).
