Abstract

1,087,041. Cutting pellets. EASTMAN KODAK CO. Nov. 18, 1964 [Nov. 18, 1963], No. 46988/64. Heading B5A. Thermoplastic sheet material, e.g. the sleavage from an extruded sheet, is formed into pellets suitable for re-use in an extruder by drawing the sheets through a cone-shaped member 13, to form a multi-ply ribbon 18 and subsequently cutting the ribbon 1, by means of a variable speed rotary cutter 21, into pellets of controlled size. The ribbon is crimped by rollers 16 and 17 to prevent its de-lamination and is drawn to the cutter by an aspirator jet 19. De-lamination may also be prevented by using heated sheets and/or by providing helical ridges to the interior of the core to impart a twist to the sheets.
