  • Apparatus and method for extrusion
    Patent number: 4609336
    Abstract: A rotatable accumulator roll which may move substantially horizontally or vertically is disposed between the die of an extruder and a take-away conveyor to minimize the effects of output surging of the extrudate from the die of the extruder in order to maintain substantially the dimension of the extrudate as delivered to a constant speed take-away conveyor. Variable force is applied to the roll to maintain tension on the extrudate.
