STORAGE HEAD FOR A BLOW MOULDING MACHINE

摘要

The invention relates to a storage head for a blow moulding machine used for the intermittent production of multi-layer co-extruded and blow-moulded thermoplastic hollow bodies. To improve the product quality and to increase throughput, each distributor is designed as a spiral channel distributor which distributes the individual molten plastic streams uniformly at the periphery. The ejector consists of a least two concentric tubular pieces and the peripherally distributed plastic streams issue from the front face of the ejector through an annular gap into the storage space in the storage head housing below the injector.
