Embossing apparatus having an embossing cylinders and embossing cylinders equipped with a system for locking the sleeve on both ends of the replaceable sleeve

摘要

Rotating cylinder for processing a web material, with cylindrical core of rigid (13) essentially is attached (45) interchangeable sleeve material expandable elastically the core, the rigid core lower than the stiffness of the material, and the sleeve can be fixed angularly and axially relative to the core, I is provided with a relief pattern on its outer surface. With a mechanical locking member of at least one at each end of the cylinder, it can be fixed to the corresponding ends of the core of the cylinder, the machine locking member interacts with the corresponding end of the interchangeable sleeve and Te, I will lock the angle with respect to the core of the embossing cylinder, the interchangeable sleeve.
