Continuous molten plastic filter - directs current obliquely through filter surface

摘要

Molten plastic is continuously filtered through a sieve, partic. by the Gneuss system with a rotary sieve disc or a standard auto-screen. The main current does not flow through the filter surface at right angles to it, but at up to 90 deg. to the flow direction. With the Gneuss system, the filter disc can be parallel to the original flow direction before entering the filter, the molten plastic passing obliquely through it. ADVANTAGE - Increases available filter area.
