Abstract
A filtration device for extrusion processes, which comprises a material intake channel, which splits into a first intake channel and a second intake channel leading to a first filter chamber and a second filter chamber, the first and second filter chambers being provided in output with a first output channel and a second output channel, which in turn merge into a channel that is adapted to convey the material to an extrusion head.

A filtration device for extrusion processes, which comprises:
- a material intake channel, which splits into a first intake channel and a second intake channel;
- a first filter chamber and a second filter chamber, wherein the first intake channel and the second intake channel lead to the first filter chamber and the second filter chamber, said first and second filter chambers being provided in output with a first output channel and a second output channel, which in turn merge into a channel that is adapted to convey the material to an extrusion head, wherein each one of said first and second filter chambers is provided with a slot for sliding a ribbon made of metal mesh;
- and
- a pushing system arranged upstream of said filter chambers, wherein said pushing system comprises a plurality of fixed toothed rollers that face a plurality of movable toothed rollers, said fixed toothed rollers being adapted to be pushed in contact with said movable toothed rollers by way of the action of springs.
