Abstract

The invention relates to a storage head for a blow moulding machine for discontinuous manufacture of multi-layer co-extruded and blow-moulded hollow bodies made of thermoplastic. To improve the product quality and to increase the throughput, each distributor element is designed as a spiral channel distributor (20) which distributes the individual molten plastic streams uniformly at the periphery. The ejector (14) consists of at least two concentric tubular pieces (42, 44, 46) and the peripherally distributed plastic streams issue from the front face of the ejector (14) and unite to form a single multi-layer flexible plastic tube in the storage space (16) in the storage head housing (10) below the ejector.
