摘要:
The invention relates to a device for partitioning the plastic parisons to give at least one semifinished open-surface product (6), where the device encompasses at least one means of partitioning (3) the plastic parison and one means of drive (2). 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.

摘要:
The present invention relates to a process for producing hollow plastic articles, encompassing the following steps: a) producing a tubular plastic parison on a blow molding plant or coextrusion blow molding plant b) cutting open the extruded or coextruded plastic parison to give at least one semifinished open-surface product c) thermoforming the resultant semifinished open-surface product to give half-shells d) welding the thermoformed half-shells to give a hollow article.
摘要:
The invention concerns a vehicle wheel, comprising a rim (1) of a plastics material and at least one adapter (5) for fastening the rim (1) to a wheel mounting (3), the at least one adapter (5) having at least one protuberance (9) which engages in a recess (11) in the rim (1), or, if multiple adapters (5) are used, at least one adapter (5) is formed such that it engages in a recess (11) of the rim over its full surface area, the adapter (5) being arranged in such a way that, after assembly of the rim (1) on the wheel mounting (3), the adapter (5) is positioned between the rim (1) and the wheel mounting (3), or the adapter (5) being arranged in such a way that the rim (1) is positioned between the wheel mounting (3) and the adapter (5), so that the adapter (5) lies on the outside of the rim (1) after assembly.
