Abstract

PURPOSE:To achieve material change with a minimum labor and time by preventing the waste of material leaving only minimal material below the surface of the accumuration detected with an upper level gauge provided in a charge hopper. CONSTITUTION:Level gauges 3 and 4 are provided each at the upper and lower positions of a charge hopper 2 of an extruder 1 and controlled by a microcomputer 9 with a level gauge 6 of a measuring hopper 5 to always detect the length l of a extruded coat strip by way of a strip length counter 10. The level gauge 3 is kept on from the start of feeding material until the quantity of material being fed determined by calculation on the value of work length L- the length l of the extruded coat strip or the like approaches the preset level of material to be used and activates the measuring hopper 5 under the control thereof to feed material. When the quantity of material fed approaches the preset level of material used, the level gauge 3 is turned off and the level gauge 4 turned on with a switching and thus, the feeding of material is continued under the control of the level gauge 4 until the quantity of material fed equals the quantity of material used.
