Abstract:
A polymer melt filtering device comprising a housing with an inflow (3) and an outflow (4) for the polymer melt, in addition to a slider (5) which can be sealingly displaced therebetween, perpendicular to said inflow and outflow. The slider (5) consists of filtering layers (7) which are supported in cavities (8) and which can be selectively placed in between the inflow and outflow. The housing is comprised of two parts (1, 2) 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 (1, 2) is floatingly mounted; in that the parts of the housing are reinforced in the middle area of the housing by beads (11), whereby the edges thereof (pressure surfaces 12) are slanted towards the outside or are conical; and in that the parts of the housing (1, 2) are maintained by clamping plates (12-15) which can be placed against each and which encompass and clamp the beads (11).
