ABSTRACT:
An apparatus for pelletizing a polymer melt, in which the polymer melt to be pelletized is divided in a housing of a pelletizing device into at least two part-streams, which are deflected and fed to at least two die plates which are spatially separate from one another and are heatable, whereupon the polymer melt streams are transformed into pellets by the cutting devices downstream of the die plates and are post-treated by means of a cooling medium. The apparatus for this has a housing (4) of a granulating device, which housing is connected to the outlet end of an extrusion device (11), with a starting valve which is arranged in the housing and is designed with a cock (1) which can be changed in its position in the housing, the cock (1) having in the operating position an inlet opening (18), connected to the extrusion device, and laterally of said opening, outlets (5) connected thereto, to which outlets there are respectively connected in the housing manifold spaces (2) which are virtually free from dead spots and connect the cock to at least two heatable die plates (3).
