Abstract
484,544. Extruding plastic substances. ARMSTRONG CORK CO. July 21, 1937, No. 20228. Convention date, July 25, 1936. [Class 87 (ii)] In extrusion apparatus for material such as comminuted cork and a binder, a part of the elongated extrusion passage is moved at the same speed as the material during part of its movement so as to reduce friction. The material is forced by a plunger 4 through a passage 2 of rectangular cross - section, the upper and lower surfaces of which are fixed while the side walls 18 are movable and extend beyond the top wall. The walls 18 are connected to the plunger 4 by a lost motion device comprising projections 24 on the plunger engaging in slots 22 in the walls. The amount of lost motion may be varied by adjusting screws 28. The material is supplied from a hopper 12 by a distributer 14 and is first compressed by the plunger 4 and then advanced together with the walls 18. The binder may be hardened by a steam jacket 30 and the hopper end is kept cool by a cooling jacket 32. In forming tubes, the outer passage 34, Fig. 3, may be fixed and the core 36 connected to the plunger by a pin-and-slot connection 40. Specification 201,623, [Class 87 (ii)], is referred to.
