ABSTRACT:
An apparatus for producing container jackets from blanks comprises a winding core around which a blank is wound in a manner forming an overlapped area. A pressing element is arranged to engage and press the overlapped area. An actuating mechanism urges the pressing element against the overlapped area to apply a pattern of radial pressing forces along the length of the overlapped area. The actuating mechanism is able to longitudinally shift the pressing force pattern along the overlapped area to adapt the apparatus to the pressing of different types of jackets, such as jackets of different lengths.
