Abstract
Apparatus for stretching a parison or a preform which is formed by a blank and where the preform is preferably intended to be reshaped into a container. In accordance with the invention the wall of the blank is provided with two laterally displaced material regions. A mechanical moulding device reduces the material thickness in the material of the wall with commencement in the region thereof where the two material regions are laterally displaced relative to one another. Lateral displacement of the material regions and reduction by the moulding device of the material thickness are selected in order to allow, respectively achieve a reduction in thickness equivalent to that the thermoplastic material obtains when it is stretched so that material flow occurs. In one embodiment the lateral displacement is achieved by the moulding device.
