Abstract: A method is described for stretch blow-moulding thermoplastics bottles (50) from heated parisons of thermoplastics material such as polypropylene. The parisons are severed from thermoplastics sticks (51) each of which is formed of several, e.g. five, parison lengths. The sticks are severed from the leading end of a continuously extended thermplastics tube, and are individually heated in an oven to orientation temperature. After heating, the sticks are presented for severance as successive groups of associated sticks which are advanced longitudinally one parison length at a time while disposed in parallel, laterally aligned relation. The bottles are formed by repeated stretch blow-moulding operations upon the groups of parisons so produced.
