Abstract

PURPOSE:To eliminate possible production of inferior goods for insufficient pressure and quantity of extrusion by securing regular supply of extrusion material such as rubber and plastic according to a signal from a sensor for detecting the presence of material on the surface of a screw located in the lower part of a material-supplying hopper. CONSTITUTION:To the upper part of a hopper 2 is fitted a sensor 8 to detect the presence of material on the surface of a screw 5. Material 1 is fed out by feeding rollers 9 and stops at the position in advance by a stated length from a cutter 10. When it comes to the condition (a) that the material is absent from the surface i.e. the bottom of a groove of the screw 5, the sensor 8 sends a signal to inform the absence of material to the cutter 10, which makes the latter operate to feed material in the hopper 2, thus the condition (b) appears. The material is thrusted into a cylinder 7 by the rotation of screw 5 and that of a feed roller 6 opposite to each other and extruded to the side of a head by the rotation of screw 5. After the operation of cutter 10, the feeding rollers 9 operate continuously, feeding out the material 1 forward by a stated length.
