ABSTRACT:
A sheet transfer apparatus which can vary the effective spacing between the cutting cylinder and the transfer cylinder and between the transfer cylinder and the folding blade cylinder in a folding cylinder group for a rotary web-fed printing press is disclosed. The cutting knives and complementary counter cut bars of the cutting and transfer cylinders, respectively, are radially adjustable on the cylinders to insure that the webs of paper are accurately cut into sheets and transferred to the pins of the folding blade cylinder. The spacings can be adjusted to allow the folding cylinder group to operate in straight, single collect, and double collect productions.
