Abstract: A cutter device for cutting thermoplastic material may be truck mounted, and includes lifting means to present articles of thermoplastic material to a portion of the device which receives the articles and hydraulically operates to transfer the article to the cylindrical portion of the device along which the article is pushed toward one end of the device where a hydraulically operated knife can selectively cut off portions of the thermoplastic material as desired. The device also includes conveyor means to transfer the cut off portions of thermoplastic materials away from the cutter device to an area where they are intended to be used. The conveyor means are hydraulically operable from the same source of hydraulic pressure as operates the other components of this device.
