Claims

[Scope of utility model registration request]

The frame 40 is equipped with a plurality of printing cylinder replacement units 43 which are detachably attached one by one to fixed positions, and two ink retainers positioned at fixed operating positions are connected to rollers 51 and 52. , one of the gears has a pitch diameter substantially equal to the outer diameter of the roller 51, and this gear in the operating position is provided so that the roller 51 and the printing cylinder driving gear 7.degree. 2, which are substantially coaxial, can rotate separately. and each exchange unit 43 has at least the plate cylinder 80 and a portion in contact with the plate cylinder 80.
A blanket cylinder 81 or an impression cylinder 82 is provided,
A gear 95 having a pitch diameter approximately equal to the outer diameter of the plate cylinder 80 is fixed to one end of the rotating shaft 94 of the plate cylinder 80, and the position of the plate cylinder 80 of each exchange unit 43 is adjusted so that the exchange unit 43 is attached to the frame 40. The printing section of a form rotary press is such that when the printing press is turned on, the printing cylinder 80 contacts the rollers 51 and 52 with a predetermined pressure.
