Use of the two superstructure units allows the folding apparatus to have a low structural height.

Abstract: A folding apparatus for a rotary printing machine utilizes a plurality of belt guide systems to retain signatures against the surfaces of the collecting, folding and gripper cylinders of the folding apparatus. The position of a longitudinal folder or of a turning bar or bars can be shifted in the axial direction of the collecting cylinder at least the width of one belt to align at least one longitudinal edge of the signatures with one of the belts in the belt guide system. The grippers on the collecting cylinder will engage the leading edge of the signatures without damaging them.

Abstract: To permit web portions (16, 17; 18, 19; 20, 21) slit from longitudinal webs (2a, 2b, 2c) to be selectively interleaved or interlaced, with or without turning over, pairs of turning bars or rods (6, 7; 8, 9; 10, 11; 12, 13) are located in essentially vertically aligned position; laterally of the turning rods, two deflection rollers (22, 23) are positioned which can be individually movably shifted by individual drive motors (32) operating a gear on a rack formed on guide rails, so that the deflection rollers can be selectively positioned at the level of a selected pair of turning rods. This permits placement of a web portion, right side up or turned over, between a pair of web portions which is not necessarily the next adjacent one in the vertical sequence of superimposed webs arriving at the interlacing or interleaving system.

Abstract: An anglebar and/or a compensator roller in a folder of a printing press is adjustable. A motor has an output shaft operatively connected with the anglebar and/or the compensator roller to, when driven, adjust the position of the anglebar and/or the compensator roller. A tachometer provides a speed reference signal indicative of the speed of movement of a web of sheet material relative to the anglebar and/or the compensator roller. A web position sensor provides an adjustment control signal indicating that the anglebar and/or the compensator roller should be adjusted. A computer responds to the speed reference signal and the adjustment control signal to control a DC drive. The DC drive drives the motor at a speed which varies with the speed of movement of the web of sheet material. The anglebar and/or the compensator roller is thereby moved to a desired position at a rate which is a function of the speed of movement of the web of sheet material relative to the anglebar and/or the compensator roller.

Abstract: To permit central control of shifting of folding blades and puncture needles on a combination collection or assembly and folding cylinder (9), the cams (23, 25l) have associated therewith rotatable cam cover disks (62, 61) which are driven from the main machine drive, for example via a drive gear (20) coupled to the cylinder (9). An additional rotary motion is superimposed to permit shifting of the cover disks and thus selectively different modes of operation, for collection or assembly, or non-collection of sequential sheet products placed on the cylinder. The superimposed motion arrangement comprises a hollow coupling gear (29) which is coupled to a worm (28) coupled therewith, the worm being engaged by axially shiftable roller bolts (36, 37), the axial position of which is controllable by an electrical positioning motor (57) via a shifting plate (47) upon rotation of a positioning spindle (52).

Abstract: The dual former (1, 2) apparatus includes a central housing and support (7) within which is retained a central common drive train (8). Located symmetrically with respect to a center line (21) through the housing and support (7) are respective transport roller units (9-12), cutting cylinder units (13, 14) and distribution apparatus units (15, 16; 27, 28), all driven from the common drive train (8). Some (9, 10) of the units may be cantilevered from the central housing and support (7), others (11, 12, 13, 14) have their remote ends journalled in bearing plates (17, 18) secured to the central housing structure (7) while still others (15, 16, 27, 28) are journalled in bearing plates secured on a base (6) which can also support the central housing structure, for example by being a metal element to which the central housing structure is welded. Delivery of folded, cut and separated printed subject goods is, preferably, laterally of the central housing structure.
