Abstract

A coextrusion adapter, including a central conduit having an inlet end and an outlet end and having bottom and top walls that define the height of the central conduit and side walls that define the width of the central conduit, as well as at least one coextrusion conduit having an inlet end and an outlet end. The outlet end feeds into the central conduit near or in the vicinity of the bottom and/or top wall thereof, downstream of the inlet end of the central conduit, and adjusting devices are provided, which are allocated to each outlet end of the at least one coextrusion conduit and are composed of a plurality of adjusting elements, which collectively extend across the width of the outlet end and by actuating drives, are adjustable independently of one another so that it is possible to change the inner width of the respective width section of the outlet end. Adjacent to the outlet end at least one of the side walls has a receiving bore into which it is possible to insert a displacing element that protrudes beyond the side wall into the central conduit.
