Abstract

414,535. Extruding sheets of celluloid &c. STELKENS, W., 47, Hansaring, Cologne, Germany. Sept. 18, 1933, Nos. 25786 and 25787. Convention dates, Sept. 19, 1932 and March 18, 1933. [Class 87 (ii).] Thin sheets of celluloid or other plastic mass are made by extruding the mass through an aperture one or more edges of which is or are movable in the direction of extrusion. In one modification, the aperture is defined by an adjustably mounted roller 4, Fig. 1, and a vertically slidable block 3 which may be adjusted by screws 6 and clamped in the adjusted position by screws passing through slots 7. The roller 4 may have end flanges defining the ends of the slot. In another modification the slot is formed by upper and lower adjustable rollers 9, 14, Fig. 3, one roller having end flanges, which may work in peripheral grooves in the other roller to constitute the ends of the slot. According to a further modification, the slot may be formed between a vertically adjustable block 21, Fig. 5, and an endless band 16, a cover plate 20 being fitted over the gap through which the band passes. The rollers or band may be positively driven or may move as a result of contact with the extruded material. A straining plate 23 and distributing segments 22 may be fitted in the extrusion nozzle 18.
