Abstract: For the sequential strapping of stacks of printed products (3) with a strapping tape (27), the stacks are conveyed to a strapping position pressed together between two presser arms (8.1 and 8.2.) and there strapped in a pressed together condition, in that a loop of the strapping tape (27) positioned around the stack (3) is tightened, locked and cut-off from a supply roll. In doing so, the tape loop is applied in the zone of the face sides of the stack outside the presser arms (8.1 and 8.2.) and aligned to slot-shaped apertures (19.1, 19.2) in the presser arms (8.1 and 8.2.) in such a manner, that the strapping tape (27), when it is being tightened, is moved through the apertures (19.1, 19.2) and comes to lie directly on the face sides of the stack. The strapping illustrated is advantageous in particular to strap stacks (3), which have either been previously - or are being simultaneously enveloped with a an enveloping material (25), whereby the envelope is applied around the stack (3) and the presser arms (8.

Abstract: To a row of winding stations (1), in which rolls (8) of flat, bendable objects (e.g., printed products) positioned on roll supports (3) are processed or in which such rolls are produced, roll supports (3) are coupled to the winding stations and if required are exchanged, the coupled roll supports forming a first row (A) of roll supports parallel to the row of winding stations (1). Roll supports (3) are positioned in readiness for the exchange in a second row (B) of roll supports, which second row (B) is distances from the first row (A) by a transport alley (10). Each roll support in the second row is aligned to the one winding station (1), to which it is to be coupled. For every exchange, the roll support (3) coupled to the winding station (1) is moved transverse to the first row (A) into the transport alley (10) and is transported along the transport alley to its end and there is positioned in a third row (C) of roll supports, which is aligned in the direction of the transport alley (10) and adjoins it.

Abstract: An apparatus has pocket-like receiving parts into which printed products are introduced by feeders. Each receiving part is assigned clamps that can be moved to transport the printed products in the longitudinal direction of the receiving part. The movement path of the clamps runs along the opening of the receiving part, and the clamps retain the printed products at their border region remote from the base of the receiving part.

Abstract: A process and apparatus for combining printed products of a plurality of types to form sets having products of each type. The first type of products are arranged in an imbricated formation in which they overlap one another in a first conveying direction and the edges run obliquely with respect to the first conveying direction. Products of another type are then deposited on the first products successively with the same alignment. Subsequent types of products may be similarly assembled to form the set of products. The formed sets having one of each type of products are then separated and conveyed in a further conveying direction which is angularly displaced from the first conveying direction.

Abstract: An apparatus for trimming multiple-sheet, folded printed products utilizing two processing drums adjacently arranged. The drums are each rotated about a horizontal axis by a drive mechanism. Each processing drum comprises radial compartments for receiving the printed products to be trimmed. Arranged on each end side of the first processing drum are two stationary cutting elements, one of which is in the operative position. The cutting element interacts with cutting elements which are fastened on the end side of the compartments on the compartment walls. In the first processing drum, the printed products are trimmed on their side borders running at right angles to the folding edge. Arranged on the circumferential edge of the second processing drum are stationary cutting elements with a cutting element in an operative position to interact with cutting elements which are assigned to the individual compartments and are arranged circumferentially in the compartments.

Abstract: Printed products are fed, from feeding sections, to the processing drum and deposited in a straddling manner on the wall elements or on printed products which have already been deposited thereon. As the processing drum revolves, the printed products are passed onto a circulating conveyor to carry out processing steps on the printed products or to add additional printed products or inserts. The printed products are then fed to the other feeding sections of the processing drum, where additional printed products are added. A removal conveyor for receiving and transporting the finished products away is located at the removal section of the processing drum.

Abstract: A method binding paper layers is based on ultrasonic joining. The paper layers are pretreated before, during or after printing with a binder by pressing or spraying on, or by shooting in droplets. The ultrasonic action is carried out by means of a control means and an ultrasonic generator (20). The latter has a conical or knife edge-like binding tool, namely the sonotrode (24). During the ultrasonic action, the latter is pressed against the layers (26), which in turn rest on a plate or wrist-like abutment (27).

Abstract: The housing has a severable projection (3) at a housing wall in which projection a channel (33, 34) extends proceeding from the interior. The channel has at least two sections (33, 34) having different cross sections that become smaller from inside toward the outside in steps. As a result thereof, an aeration opening of differing sizes can be created for different applications of the component by parting the peg at different locations.

Abstract: A stapling apparatus is provided. The stapling apparatus includes a shaft which is swivelably mounted on a supporting part of a stapling head. The stamp is seated rotationally firmly on the shaft. For the purpose of accepting a wire section from a wire section dispenser, the shaft can be swiveled clockwise by 180.degree. from its staple placing position. The wire section accepted by the stamp is formed into a staple on a slotted link. The lateral arms of the staple are guided in grooves of the stamp arms. In the staple placing position, the staple is ejected from the stamp by means of a ram.

Abstract: Cams (36, 36') are arranged in each case laterally offset alternately on the chain (34) of the cam conveyor (30). The cams (36) are swivelled by the swivel rocker arm (44) into catching position (46), in which they are always actively conveying. Depending on the position of the control rocker arm (54), the cams (36') which can be switched away are left in their rest position (50) or likewise swivelled into the catching position (46). A retaining device (56), which holds back the printing products (18) deposited thereupon until they are pushed off by a cam (36, 36'), is provided at the depositing point (24). With the cams (36') which can be switched away actively conveying, each printing product 18 is individually seized by a cam (36, 36') and conveyed away in an imbricated formation.

Abstract: Grippers or gripper elements are attached at conveyor chain links of a revolvingly driven conveyor chain. The leading edges of each product of an imbricated product formation, in which each product bears upon the next following or trailing product, comes to lie on a clamping jaw of an associated gripper or gripper element and is engaged from above by a clamping element, such as a clamping finger of such gripper or gripper element. The product conveying direction of the transport apparatus and the product conveying direction of an infeed device delivering the products are in the same direction at a product take-over region of the transport apparatus. During the closing motion of the clamping finger of the gripper or gripper element this clamping finger raises a region or portion of the preceding or leading product which covers the leading edge of the trailing product which is to be engaged by such gripper or gripper element.

Abstract: Continuously conveyed flexible flat structures, especially printed products, infed in an imbricated formation, are turned such as to retain their original imbricated product formation. This is accomplished by accelerating the flexible flat structures such that they are singled and then in such singled condition are deflected about a deflection axis directed transverse to the product infeed conveying direction. Thereafter the singled turned flat structures are decelerated and transported away in an opposite conveying direction. Between an infeed device and an outfeed device for the structures there is arranged a deflection mechanism comprising at least one endless revolving driven traction element guided between its two substantially linearly extending runs about a deflection wheel. This traction element has mutually spaced outwardly extending carrier or support elements, at the outer ends of which there are mounted controlled grippers for engaging a respective one of the flat structures.

Abstract: In a relay which has a coil body as a base body, an insulating cap of foil material is inverted over the wound coil body. The insulating cap is adapted to the outer contour of the wound coil and having a semi-cylindrical center section covering the upper half of the winding and pockets adapted to the coil body flanges. As a result thereof, the insulating cap is provided with good stability and is therefore protected against deformation and damage.

Abstract: The relay has a flat armature (6) carried at one bearing edge (15) of a yoke arm (5a), which is attached via an armature retaining spring (8). In order to protect the armature against shocks, the exposed section (18) of the armature retaining spring (8) engages with one or several extensions (6a) of the armature. In the event of shocks occurring in the direction parallel to the coil axis, the armature is only able to move slightly and then it knocks against the terminal edges (16) of the exposed spring sections (18).

Abstract: At a moveable frame there is rotatably mounted a driveable winding core. The one end of a tension-resistant winding band is connected with this winding core, and such winding band is wound-up upon a band spool. This band spool is rotatably mounted in arm members of the frame. Acting upon the shaft of the winding core is a jaw brake. The shaft of the band spool is likewise brakeable and blockable by means of a jaw brake. The frame together with the winding core, band spool and the therebetween traveling winding band can be transported. For winding-up flat products or the like the shaft of the winding core is driven, and the jaw brake effective upon such shaft is opened or retracted. The band spool is slightly braked by the jaw brake associated with the shaft of the band spool. The flat products are infed to a winding gap and together with the winding band which is under tension wound-up upon the winding core.

Abstract: A portable electric stapler wherein a bladelike impeller is reciprocable by the armature of an electromagnet which is energizable a selected number of times so that a staple which is introduced into a housing channel in front of the impeller is gradually driven into a workpiece. The magazine for staples and that part of the housing which defines the channel are movable relative to the impeller between a first position in which a pusher can expel a staple from the magazine into the channel and a second position whereby the impeller separates the foremost staple from the stack of coherent staples in the magazine. The impeller blocks the outlet of the magazine during the intervals between successive energizations of the electromagnet to thus prevent entry of a fresh staple into the channel before the driving of the preceding staple into the workpiece is completed. The rearward movements of the armature and the impeller are braked by a pneumatic brake or by a shock absorber.

Abstract: The coil form has auxiliary points of support for the winding ends in the form of two retaining lugs each, which enclose between them a breakthrough in the coil form. After the coil is wound, a metallic connecting element can be inserted into this breakthrough so that its free end is positioned between the retaining lugs and can be soldered to the winding ends already applied to the retaining lugs.
