The present invention relates to a multistage process for producing hollow plastic articles, encompassing the following steps:

Multistage process for producing hollow plastic articles from half shells

A bumper system for a motor vehicle includes, but is not limited to, a bumper cross member, which is fixed to a stiff frame of the motor vehicle, a pliable bumper shell, a compressible structure which is formed between an upper area of the shell and the cross member and one support section which supports the lower area of the shell, which, together with a crash box holding the cross member is anchored to the flange plates of the frame.

The invention relates to a device for partitioning the plastic parisons to give at least one semifinished open-surface product (), where the device encompasses at least one means of partitioning () the plastic parison and one means of drive (). The means of drive may be composed of one, but preferably of two, driven rolls. It has been found that use of the device of the invention can reduce or prevent the production of creasing and irregularity at the margins, i.e. at the cut edges, of the partitioned parisons, i.e. of the resultant semifinished sheets.
