Abstract: An improvement in the method and apparatus for folding newspaper in the "collect" mode. Inside and outside web sections are printed with the same number of lines and transferred to a folding cylinder which collects them in overlapping relation. Expanding means incorporated in the body of the cylinder expand its effective radius to permit the trailing edge of the outside section to be cut to a length equal to that of the inside section without recutting the inside section. The collected sections are then passed through second fold rollers for final folding.

Abstract: A method and apparatus for reducing the cutoff length of a duel web folding and cutting assembly. The method comprises steps of reducing the support surface under the working parts of the folding cylinder along the length of a roller which contacts the web such that the working parts may be replaced without modification. Further, the cutting rollers reduced in diameter must be moved closer to the folding cylinder. One method of moving the cutting cylinder is by reboreing the mounting hole for one end of the cutting cylinder on the drive side to enable placement of sleeve having eccentric center holes in each side frame to move the cylinder closer. The other method comprises steps of cutting the driven side of the cutting cylinder support shaft off positioning it in an auxiliary side frame mounted inside of the old side frame and driving cutting cylinder with gears positioned inide of the auxiliary side frame.

Abstract: A signature transfer device in a folder for a rotary printing press includes a plurality of adjustable-pressure rollers for holding down upper tapes for transferring a signature with a strong force to prevent the upper tapes from slipping on the signature and hence, to prevent the latter from being inclined while the signature is being transferred toward a position in which the signature will be folded on itself by a chopper blade. The signature transfer device includes an adjustment mechanism for adjusting gaps between the upper tapes and the lower tapes to reduce the force with which the signature is sandwiched between the upper and lower tapes, so that the signature is prevented from being forcibly pressed against front lays in the folding position. With this arrangement, the signature is prevented from getting wrinkled upon abutment against the front lays, and from becoming inclined relative to the chopper blade when the signature approaches and arrives at the folding position.

Abstract: A variable size folder cylinder for a web-fed rotary printing machine is disclosed. Spaced inner support wheels and spaced outer support wheels are carried by a common shaft. The inner and outer wheels serve as support for sheet grippers, folding blades and the like. The inner wheels and outer wheels are rotatable on the shaft with respect to each other so that the elements which they carry can be variably spaced about the periphery of the folder cylinder. A clutch assembly is carried by adjacent ones of these inner and outer support wheels with the clutch including a ring-shaped piston that carries a coupling ring which is brought into engagement with a thrust collar. A flexible membrane return ring is sealed between the ring-shaped piston and the face of the surrounding wall of the support wheel and acts to return the piston its rest position when actuating pressure is removed.
