  • Mandrel for printing apparatus, a printing cylinder, a printing apparatus
    Patent number: 11198286
    Abstract: A mandrel for use in a printing apparatus includes a substantially cylindrical mandrel shaft and a locking assembly including a stop ring, a locking ring, and a plurality of deformable rings which are slidably and coaxially mounted on the mandrel shaft. Each deformable ring has a cross-sectional profile in a cross-sectional plane in which the mandrel shaft axis extends, which profile includes a first arm and a second arm which are integrally connected to each other at a first connection point. The first arm and the second arms include an angle which is sharper in the unlocked position than in the locked position of the locking assembly. The first arm has a first-arm-end remote from the first connection point, which defines the outer diameter of the deformable ring. The second arm has a second-arm-end remote from the first connection point, which second-arm-end defines the inner diameter of the deformable ring.
