Abstract
PURPOSE: To reduce the loss of materials and paper by detecting paper jointing operation in exchanging web and detecting paper joint in the course of taking-up and permitting drawing-out operation of a printing drum immediately before paper joint passes and putting-in operation of the printing drum immediately after passing, in an offset rotary press.
CONSTITUTION: Eccentric sleeves 6 and 7 which suspend the shafts 6' and 7' of blanket drums 2 and 3 are set in free jolting, having supporting shafts 8 and 9 as center, and both sleeves 6 and 7 are contacted with a rod 10. The time and the distance in which the paper joint arrives at each colour printing unit 1u, 2u, 3u, 4u from the signal taking-out part, after a joint detecting device 1 detects a paper joint b, is checked beforehand, and a timer or the revolution of the printing press is set, and the printing press is constituted so that drawing-in and -out of the blanket drums is carried out in regular order and each air cylinder 12 is operated.
