<p>PURPOSE:To make it easier to clean the front side etc., of a main body of an extruder by providing a mounting base, which is vertically movable and can be fixed at the lower position, on said main body through a guide member, and mounting a movable member and a sensor on said base to greatly raise said movable member. CONSTITUTION:A mounting base 11, which is vertically movable and can be fixed at the lower position A, is provided on a main body 1 of an extruder through a guide member 14 and a movable member 9 and a sensor 23 are mounted on said base 11. For extruding a rubber sheet etc., the base 11 is fixed at the position A, and then the member 9 vertically moves corresponding to the change in the quantity of bank, whereupon the sensor 23 catches said movement as electric signals, so that feedback control is effected to keep the quantity of bank at a nearly constant value. To clean the front side etc., of the member 9 and the main body 1, the base 11 is released and raised to the upper limit along the member 14, whereby, since both the member 9 and sensor 23 are raised, a space required for cleaning is provided. As a result, the cleaning can be easily carried out without moving calender rolls 5, 6.</p> |
