Abstract

DC60 (27/09/43) The extruder template plate is directly connected to the fluid driven motor on one side and to the extruder on the other side. Suitable fluid inlets and outlets are formed in the template plate to supply the fluid to the motor and to suck the fluid out. The cutter assembly consists of a housing which receives the motor inside and is connected for rotation to the motor's take-out shaft so that when in use, the cutter knife mounted on the housing is made to rotate in the path of the extruded material and cuts the extruded material off.

Claims (3)

A mold plate for an extruder, wherein the mold plate has a first connection means for connecting the mold plate on its first side to an extruder defining the longitudinal axis, and a channel through which the extruded material is received by the extruder and extruded for cutting to a predetermined length by a cutter assembly disposed on said longitudinal axis. The cutter assembly is of the type having a fluid-driven motor for rotating the cutter transversely to said longitudinal axis in the path of motion of the extruder to cut the extruded material into pieces for use. The mold plate further comprises a second connection means for connecting the mold plate on its second side to said cutter assembly, a fluid inlet for receiving fluid into the mold plate for delivery to said cutter assembly for use, and a fluid outlet for receiving fluid from said cutter assembly for dispensing from the mold plate. 2. The mold plate of claim 1, having an outer rim adjacent to said first and second sides, a fluid inlet and a fluid outlet, each having a radial portion. 3. The mold plate of claim 1 or 2, wherein said first and second connecting means comprise a plurality of mounting openings for receiving each of the fasteners through the mold plate. 4. The mold plate of any one of the aforementioned claims, having a thermally insulated means between the inlet and outlet ports of the fluid and the channels of the extruded material. 5. The mold plate of claim 4, wherein the insulated means comprise a gap through which gas can pass. 6. An assembly comprising a mold plate, a cutter assembly and a fluid-driven motor, the mold plate having a first connecting means for connecting the mold plate on its first side to an extruder defining the longitudinal axis, and comprising a channel through which the extruded material is received by the extruder and extruded for cutting to a predetermined length by said cutter assembly. The cutter assembly arranged on said longitudinal axis and comprising a rotating cutter driven for rotation transversely with said longitudinal axis by said motor in the path of motion of the extruded material to cut the extruded material into pieces for use. The assembly further comprises a second connecting means for connecting a template plate on its second side to the cutter assembly, and wherein the template plate comprises a fluid inlet for receiving fluid for delivery to said cutter assembly and a fluid outlet for receiving fluid from said cutter assembly for dispensing from the template plate, and wherein a fluid-driven motor is connected to said second side of the template plate and is adjusted for motor-driven fluid from said fluid inlet and for dispensing said fluid to said fluid outlet. 7. The assembly of claim 6, wherein the rotating cutter comprises a housing connected for rotation to said motor, the motor being held within said housing. 8. The assembly of claim 6 or 7, wherein the housing comprises a blade mounting means for supporting at least one radially projecting blade having specified spacing. 9. The assembly of any one of claims 6 to 8, wherein the first and second connecting ways comprise oppositely oriented conical openings each 1 0. The assembly of any one of claims 6 to 9, wherein the motor is a hydraulic motor 1 1. The assembly of any one of claims 6 to 9, wherein the mold plate comprises a thermal insulation means between the inlet and outlet ports of the fluid and the extruded material channel 1. 2. The assembly according to claim 11, wherein the insulating means comprises a gap 1. 3. The assembly according to claim 12, wherein the cavity is filled with gas.
