Cross discharge head for extrusion equipment

Abstract

The invention relates to a cross discharge head for extrusion equipment comprising a housing to be mounted on an extruder, which in its interior receives an annular feeding channel encompassing a passage, disposed in the housing and disposed at an angle to the direction of extrusion of the extruder, for the supply of a product to be ensheathed with the extrudate, which receives in its interior a distributor piece, and which at the exit is provided with annular outer shaping tools tapering the stream of extrudate, which are secured on the front face of the housing so as to be exchangeable, wherein the passage at the end side is encompassed by a conical guidance nipple whose outside is simultaneously also the inner shaping tool. The invention creates with simple means a short, stout and compact cross discharge head which can be cleaned readily and rapidly without disassembling its individual structural parts, can be adjusted rapidly and without problems and whose faces bringing about the distribution and shaping of the stream of extrudate can be reworked without any problem and entail the capability of being readily replaceable. The invention comprises that the outer shaping tools form a fixedly contiguous assembly unit which is secured on the housing and which can be dismounted as such from the housing, that the annular feeding channel disposed in the housing is disposed directly in the parting plane of the housing and the assembly unit comprising the shaping tools.
