Abstract

117,097. Stratton, J., and Claremont,E. A. April 30, 1917. Extrusion machines.-A machine for extruding plastic rubber &c. in pipe or other form has a chamber a' in the form of two intersecting parallel cylinders, in each of which is a rotating roller b extending from end to end, and having parallel interengaging ribs or teeth b<1>, between which the plastic material is carried to an opening in the side of the chamber and forced through a jacketed chamber in a box d, which surrounds a projection c<4> of the frame and an attached core c<3>, and is fitted with a removable die d<1>. The rubber &c. may be supplied in strip form from a table f<2>, between lateral guides and adjustable plain rollers f, and through passages c. The teeth on the rollers b may be parallel or slightly inclined to the axes, the flow of the material being at right-angles to the axes. To enable a cable &c. to be covered by the machine, the roller chamber may be divided by a central transverse wall having a sleeve-lined passage way for the cable, or the rollers may have a central groove receiving a sleeve. The extruding-rollers may be driven through a change-speed gear box, and the extruded article received by an adjustable band conveyer driven through a variable-speed mechanism. The walls of the roller chamber open at the line a<2>, one part turning about a hinge a<3> under the control of a winch handle and chain gear, and the part a<4> of the frame, which carries the rollers f, can separate from the main body at the line a<5> by turning about a hinge a<6>.
