Abstract: A device for conveying flat floppy products has an inlet conveyor belt with a constant velocity, an intermediate conveyor belt with a periodically changing velocity and an outlet conveyor belt with constant velocity. The intermediate conveyor belt causes a deceleration or acceleration of the product to be conveyed. Transfer of the product between the conveyor belts takes place at respectively the same velocities of the affected belts. The drive of the intermediate conveyor belt is performed by a gear making periodic gear changes. The invention relates to the relationship between the shaft distance and the radius of the drive pulley of the intermediate conveyor belt and is particularly related to steps reducing the torque during acceleration or deceleration of the drive elements and assuring a slip-free conveyance of the products.

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: A folding apparatus for rotary printing presses uses at least a single stage speed reducing device between a collection cylinder and a folding blade cylinder to reduce the speed of travel of signatures before they are cross-folded. The reduction in the speed of travel of the signatures eliminates damage to the signatures during their cross folding while allowing the printing press to operate at a high rate of speed.

Abstract: A folder for a web-fed rotary printing press includes a cooperating pair of collection and cutting cylinders to sever a paper web into web segments. A belt conveyor system enwraps a portion of the surface of the collection cylinder just before an intake point of the paper ribbon between the collection cylinder and the cutting cylinder. This belt conveyor system prevents the newly created leading edge of the paper ribbon from springing back.

Abstract: A longitudinal folding device for folding symmetrical and asymmetrical paper products has a folding blade and cooperating folding rollers whose positions with respect to each other can be varied. The folding blade or the folding roller pair can be shifted laterally with respect to a longitudinal fold line. In addition, the spacing between the folding rollers can be adjusted in accordance with paper thickness and number of sheets in the product to be folded.

Abstract: In the context of a folding device comprising at least one transverse folding part which is supplied and discharged by feed tapes and is in the form of a buckle folder with a buckle passage flanked by two outer rolls cooperating with a center roll with the formation of feed nips, such folder having a set of tapes running through it over the center roll, a greater degree of adaptability to the processing of different products and of possibilities of modification of the feed paths may be ensured if the outer roll on the delivery side may be pivoted away from the center roll so as to open up and render ineffective the delivery feed roll nip and the buckle passage may be shifted so that its inlet is over the inlet-side feed plane of the tape set running over the center roll.

Abstract: Sheet-like products coming off a folder are firstly transported some distance before being caused to overlap. In order to slow down the products to cause this to take place and to arrange them in a perfectly regular feed stream without being damaged, the products are engaged by grippers that are moved along a preferably arcuate path on a support in the course of which the products are slowed down by the grippers to the speed of a delivery belt on which the products are then deposited.

Abstract: In connection with an apparatus for putting paste on a moving printed paper web in strips at a right angle to the direction of motion of the web by moving the web between a pasting cylinder and a web support part on the other side of the web, one purpose of the invention is to make certain that the strips of paste may be put on at a high speed and to have such a design that the upkeep work on the apparatus is simple and may be done quickly. To make this possible, the pasting cylinder is made up of cylinder body and a paster roll placed within it so that a limited area of its outer face is uncovered by an axial slot in the outer face of the body. The paster roll has one or more wells stretching along it that are topped up with paste at a point within the pasting cylinder body, while the parts of the outer face of the roll between the wells are stripped and kept clear of the paste.

Abstract: For the purpose of helping in the making of a second lengthways fold in a web of paper in a folder having a folder blade for producing this fold, the paper is firstly scored at the desired fold position in the long direction by a sharp-edged wheel pushing the paper against a turning back-up part, which is let into the face of one of the nipper or guiding rolls of the folder. The wheel with the sharp edge is placed on the other, opposite roll between separate roll parts or wheels thereon gripping the web against the other roll.
