#CMT# #/CMT# The head has a distribution unit distributing plastic melt to an outlet, where the distribution unit has a distribution plate, a channel system, rising bores (12, 21) and a spiral distributor (13). The channel system is fluidically connected with an inlet and the rising bores that are fluidically connected with the spiral distributor. The distribution unit has set screws (15) for decreasing or increasing material thickness of a blow film discharged from the outlet, where the screws are manually adjustable. #CMT#USE : #/CMT# Blow head for a blown film extrusion system. #CMT#ADVANTAGE : #/CMT# The distribution unit has the set screws for decreasing or increasing the material thickness of the blow film discharged from the outlet, thus reducing cost of the blown film extrusion system, and increasing quality of the blow film. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic three-dimensional bottom view of a spiral distributor. 12, 21 : Rising bores 13 : Spiral distributor 15 : Set screws 23 : Fastening unit 24 : Fastening unit. |
