FIELD: process engineering.
SUBSTANCE: numbering system is designed to be incorporated with printing machine and consists of numbering cylinder, rotary shaft, at least, one supporting disk fitted in said shaft to revolve therewith. Support disk comprises peripheral set ring to mount at least one numbering device 2.06 on support disk periphery. Said device 2.06 is secured to peripheral et ring by means of locking mechanism. Peripheral set ring features T-cross section that defines two annular mounting grooves on each side of the ring. Numbering device 2.06 has its each side supporting locking elements 2.50 to interact with annular mounting grooves for attachment of numbering device to peripheral set ring. Locking elements 2.50 represent, preferably, spring-loaded locking elements.
EFFECT: higher reliability, simplified design.
