Abstract

See full text

A device for filtering a plastic melt, having a housing that has at least one inlet passage and at least one outlet passage for the plastic melt. The at least one inlet passage is separated from the at least one outlet passage by at least one filter cavity for accommodating at least one filter piston that is axially displaceable therein. The at least one filter piston has at least one filter base body with a filter surface with filter openings passing through the filter base body there, through which openings the plastic melt passes into a filtrate cavity in the filter base body. The filtrate cavity is fluidically connected to the at least one outlet passage, and the filter surface of the filter base body is enclosed by a flexible, elastic filter screen in such a manner that this filter screen can be clamped onto the filter base body there.
