Patent ID: 8617344

Claim:
A process for producing hollow plastic articles comprising the steps: a) producing a tubular plastic parison by means of extrusion or coextrusion; b) cutting open the tubular plastic parison with a cutting device to produce two planar-surface parts using pneumatically driven rollers arranged in the immediate vicinity of the cutting device for distancing the two planar-surface parts from the cutting device immediately after separation of the parison; c) molding the planar-surface parts in two mold halves to give half shells, where a removable intermediate frame separates the mold halves from one another at least along peripheral edges, wherein the planar-surface parts and half shells are not in contact with one another; d) opening the mold halves and removing the intermediate frame; e) closing the mold halves, wherein the half shells come into contact with one another along a peripheral rim; and f) bonding the half shells wherein the driven rollers are integrated within the cutting device.
