Abstract
The invention considerably reduces the danger of deformation for containers made from a thermoplastic material during the transfer to a stacking magazine or into a locally fixed catch plate. This deformation danger results from the fact that the formed stack must be displaced within a short time by the stack distance, either through the transferred containers themselves or by components of a catch plate that is moved forward with each cycle. This is achieved through displacing the stacks in the stacking magazines or the locally fixed catch plate with a displacement device. The displacement device can be combined with the stack removal device or can be a separate displacement device. According to a modification of the invention, the method is intended to improve the cooling of the stacked containers.
