Abstract
A polymer melt filtering device comprising a housing with an inflow ( ) and an outflow ( ) for the polymer melt, in addition to a slider ( ) which can be sealingly displaced therebetween, perpendicular to said inflow and outflow. The slider ( ) consists of filtering layers ( ) which are supported in cavities ( ) and which can be selectively placed in between the inflow and outflow. The housing is comprised of two parts ( ) that are arranged in such a way that their front surfaces face towards each other. The inventive device is characterised in that one of the parts of the housing ( ) is floatingly mounted; in that the parts of the housing are reinforced in the middle area of the housing by beads ( ), whereby the edges thereof (pressure surfaces ) are slanted towards the outside or are conical; and in that the parts of the housing ( ) are maintained by clamping plates ( ) which can be placed against each and which encompass and clamp the beads ( ).
