摘要： An extruding machine for plastic material and the like comprising one or more worm spindles (1). Each spindle is divided in two end portions (2, 3) and an intermediate portion (4). The two end portions of each spindle are designed as worms (5, 6) with opposite directed screws, the worm portions being positioned in a cylindrical housing respectively (8, 9) while the intermediate portion (4) of the spindle is located in a receiving chamber (7) positioned in between said cylinders.
The material to be extruded is supplied by respective hoppers (12 and 13) each arranged at the end of the cylinder remote from the chamber (7). So the worms (5 and 6) push the material from two opposite sides into the receiving chamber from where it is passed to the machine die by deflecting inner walls 10 of said chamber.
