ABSTRACT:
A nozzle cartridge installed between a wall and a counter platen has a spreader arranged in a shell which extends as far as the rear end of the spreaded and is formed with a plane end face which contacts a plane area of the counter platen, the shell being clamped between the wall and the counter platen so that movements of the counter platen relative to the wall cannot affect the position of the spreader relative to the shell and thereby the influence on the plastic stream emitted from the nozzle is greatly reduced.
