Abstract
A method and an apparatus for making blow-moulded bottle from a preform consisting of at least three layers. For making the preform a tube section heated at one end is shaped by pushing into a closed bottom mould to form a bottom and pressure is exerted in the axial direction on the center bottom region to close the still present gaps in an outer layer as soon as an inner layer has flowed together.
