ABSTRACT:
A change device for sieves used for filtering plastic materials. The change device comprises a sieve holder having a bore for the throughflowing material and a slot extending transversely thereto, in which there are sealingly retained in work position sieve supports or carriers containing sieves. By means of a work cylinder it is possible, without interrupting the transport of the material which is being processed, to eject and replace the contaminated sieve by a new sieve. The rapid change device is particularly suitable for installation in an extruder for fabricating rubber hoses for automobile tires, the installation of such rapid change device advantageously being accomplished between the extruder and the injection head.
