DETAILED DESCRIPTION In General In general, FIGS.
1-5 show a decorator apparatus comprising a mandrel wheel means 30 for receiving undecorated can body members 32 from an infeed means 34.
Can body members 32 are supported on a plurality of equally circumferential spaced mandrel means 36 for movement with the mandrel wheel means past a blanket wheel means 38 which carries a plurality of circumferentially spaced blanket segment means 40 having ink and inked images thereon.
Each blanket segment means 40 engages the cylindrical outer peripheral surface of a can body member 32 to apply variable color ink and ink images thereon in the form of a label including a brand name, printed matter, decorative images, etc.
An overvarnish means 41 may be provided to apply an overvarnish coating material to the inked can members as described in U.
S.
Pat.
No.
4,441,418.
Decorated can body members 42 are carried to a transfer wheel means 44 and transferred from the mandrels 36 to carrying devices 46 such as suction cup support members as described in U.
S.
Pat.
Nos.
4,445,431 and 4,509,555.
Decorated can members are carried on transfer wheel means 44 to a pin-chain means 47 driven by a sprocket wheel means 48 and having pin members 49, which receive the decorated can members from the transfer wheel means 44.
An electric motor-type drive means 50 is connected by suitable transmission apparatus to each of the driven devices, FIGS.
2, 3, including belt means 51, gear box means 52, belt means 53, a main shaft means 54, gear box means 55 for driving the mandrel wheel and the transfer wheel, belt driven gear box means 55A for driving the overvarnish means 41, shaft and coupling means 56, belt and pulley means 56A, gear box means 57 for driving the blanket wheel and associated plate cylinders 70, shaft and coupling means 58, gear box means 59 and 59A and shaft and anti-vibration coupling means 59B and belt-pulley means 60 for driving the inker station roll systems, all of which are synchronously driven for the intended purposes
