ABSTRACT:
Continuous web-fed rotary tuck and jaw type folding apparatus, typically for high speed periodical, catalogue or newspaper production, is speedily and readily convertible to produce differently page sized and differently folded signatures. Said apparatus has severing means for cutting the web into a stream of discrete signatures; a first rotary cylinder having pin or other transport means and first tuck means carrying those signatures on its periphery, a second rotary cylinder having first or main jaw means coacting with said first tuck means whereby a central cross fold is created in each signature as it is taken off the first cylinder periphery onto the second cylinder periphery to provide a tabloid format signature; and one or more third cylinders each provided with independently operable sets of gripper and second jaw means, the gripper means operating with the third cylinder running in timed relationship so that they take off said tabloid folded signatures for onward transmission, and the second jaw means operating with the third cylinder running in timed relationship to second tucking means of the second cylinder so as to form a further central cross fold in each tabloid signature as it is taken off the second cylinder periphery to provide a double-parallel folded signature.
