Patent ID: 7523700

Claim:
A cylinder usable to process sheet material comprising: a cylinder body having a cylinder body circumference and a cylinder axis and being rotatable about said cylinder axis; a number “n” of groups of tools distributed evenly over said cylinder body circumference and being adapted to perform an operating movement with respect to said cylinder body; a control arrangement for each of said groups of tools and usable to drive said operating movement of said group of tools; a stationary cam disk traced by each said control arrangement; a rotatable cover disk, said rotatable cover disk being coupled to the rotation of said cylinder body and being traced by each said control arrangement; a number “m” of congruent sectors on said cover disk and each of said sectors having at least one section of a first radius, each said first radius section, when it is traced by said control arrangement, allowing said operating movement of said one of said groups of tools associated with said control arrangement, each said sector also having at least one section of a second radius which is different from said first radius, each said second radius section, when it is traced by said control assembly, blocking said operating movement of said one of said groups of tools associated with said control arrangement, said number “m” of said sectors being at least equal to “n”/(2+1), a ratio of a number of rotations of said cylinder and of said cover disk being 1:1±1/“p”×“m” wherein “p” is a whole number ≧2.
