Abstract

1,216,527. Cooling extruded articles. FMC CORP. 9 Aug., 1968 [31 Oct., 1967], No. 38178/68. Heading B5A. The apparatus described in Specification 1,075,565 for cooling polymeric, rectangular cross-sectioned extrudate 16 is modified by replacing a smooth continuous arcuate surface over which the extrudate slides by transversely extending tubes 26, 28, 30 &c. about which the extrudate is laced. Tubes 26, 28, 30 &c. are open-ended and extend between vertical walls (42), Fig. 2 (not shown), and 44 fixed to, but spaced from, the adjacent vertical walls of tank 18. The water in tank 18 is thereby enabled to flow through the tubes. The number of tubes employed is proportional to the thickness of the extrudate.
