Patent ID: 7156018

Claim:
A printing group of a printing press comprising: a first forme cylinder having a first forme cylinder axis of rotation; a first transfer cylinder having a first transfer cylinder axis of rotation and being engageable with said first forme cylinder; a second transfer cylinder having a second transfer cylinder axis of rotation and being engageable with said first transfer cylinder in a print-on position, a web to be printed having a web first side engaged by said first transfer cylinder and a web second side engaged by said second transfer cylinder in said print-on position; a second forme cylinder having a second forme cylinder axis of rotation and being engageable with said second transfer cylinder; a common plane defined by said axes of rotation of said first and second forme cylinders and said first and second transfer cylinders in said print-on position; a first lever having a first end supporting said first transfer cylinder for rotation about said first transfer cylinder axis of rotation and having a second end pivotable about a first lever pivot axis, said first lever pivot axis being located on said web first side of said printing group; a first setting means contacting said first lever to pivot said first lever about said first lever pivot axis, said first setting means being usable to selectively place said first transfer cylinder into and out of contact with said first forme cylinder and said second transfer cylinder; a first lever length between said axis of rotation of said first transfer cylinder and said first lever pivot axis; a first spacing distance between said first forme cylinder axis of rotation and said first transfer cylinder axis of rotation in said print-on position, said first lever length being greater than said first spacing distance; a second lever having a first end supporting said second transfer cylinder for rotation about said second transfer cylinder axis of rotation, and a second end pivotable about a second lever pivot axis, said second lever pivot axis being located on said web second side of said printing group; a second setting means contacting said second lever to pivot said second lever about said second lever pivot axis, said second setting means being usable to selectively place said second transfer cylinder into and out of contact with said second forme cylinder and said first transfer cylinder; a second lever length between said axis of rotation of said second transfer cylinder and said second lever pivot axis; and a second spacing distance between said second forme cylinder axis of rotation and said second transfer cylinder axis of rotation in said print-on position, said second lever length being greater than said second spacing distance, said first lever pivot axis being located on a first side of said common plane, said second lever pivot axis being located on a second side of said common plane which is opposite from said first side of said common plane.
