Abstract
Blow moulded thermoplastic articles are produced by forming a longitudinally drawn preform, setting the unheated end of the preform in a holding device, pinching off the other, heated end of the preform, and blowing the internal pressure in a mould at a temp. below its crystalline m.p.
TOOL FOR INJECTION MOLDING WITH ONE OSCILLATING AND ONE FIXED PART FOR THE PRODUCTION OF FLEXIBLE SHEET HOSES FROM THERMOPLASTIC MASSES BY MEANS OF THE BLOWING PROCESS IN HORIZONTAL PROCESSING
