In the printing industry, and even more specifically in the digital printing industry, the use in highly accurate printing cylinders with small runout is verry common. In order to meet accuracy demands and allow simple and easy removal for maintenance purposes, the printing cylinder is usually positioned upon 2 tapered areas. A combination of thermal deformation upon the tapered areas (especially when the cylinder and tapered areas are made of different materials with different coefficients of thermal expansion), with the shallow taper angle, and the contact friction creates a situation of “self-locking”, which “binds” the cylinder to the tapered areas firmly together.

This document will introduce a method for releasing the cylinder binding, allow simple cylinder replacement while dramatically reducing the potential for mechanical cylinder damage.
