Flat articles are inserted into printed products () continuously conveyed by grippers () of a gripper conveyor (), wherein the printed products are held by the grippers at their fold or spine edges and wherein the grippers () are conveyed through a deflection region from below round an essentially horizontal deflection axis (). Pegging elements () rotating around the deflection axis () are arranged along both sides of the deflection region and synchronized with the grippers, and form axially aligned and inter-spaced pairs and are radially distanced from the grippers. The printed products () are conveyed in a hanging manner into the deflection region and they are opened immediately upstream of the deflection region. The pegging elements () are activated as the grippers () enter the deflection region to grab the trailing part () of one opened printed product () and the leading part () of the next product by the corners opposite the fold or spine edge by clamping them together until the grippers () exit the deflection region.

Method and device for inserting flat articles into printed products

A method of combining a number of individually printed products into a finished product, for example a weekend newspaper containing numerous sections. The individually printed products are of the type that are folded at their mid portion so that they can be opened along the fold allowing them to receive other printed product or closed which facilitates their insertion into an opened printed product. The process starts by inserting a folded printed product into the main product. The first inserted product could have been open when inserted or opened after it was inserted. Then another printed product is inserted into the main product such that it lies adjacent to the first product that was inserted. The first product that was inserted into the main product can then be opened to permit additional printed products to be inserted into it.

Products (2) made of paper or similar materials are cut along predetermined cutting lines in a drawing cut between crossed knife edges while being conveyed continuously in a dense conveying stream in which their main surfaces are orientated substantially perpendicular to the conveying direction (v). For this purpose a counter knife (1) with a guide edge (11) is allocated to each product (2) and the products (2) together with the counter knives (1) are conveyed past at least one cutting knife (5) with a cutting edge (51) having two ends, whereby the cutting edge (51) of the cutting knife (5) substantially lies in the plain formed by the guide edges (11) of the counter knives (1) and forms a cutting angle (.alpha.) with the guide edges (11). While the cutting edge (51) forms a cutting formation with one guide edge (11) in which cutting operation the two edges are intersecting in a cutting area (4) being shifted along the cutting line, the cutting knife (5) is additionally drawn in a direction (Z) parallel to the guide edge (11) or along the cutting edge (Z') or in a direction lying in between said two direction and opposed to the direction in which the cutting area (4) is shifted. Between successive cutting operation with successive counter knives (1), the cutting knife (5) is reset (R, R') in an direction opposed to the direction of the drawing movement (Z, Z').

A cutting device for elongated objects, especially for wire, having a cutting element which is movable relative to a shearing element by means of a drive. The cutting element is of disk-shaped configuration and its periphery is configured, at least in segments, as a cutter. The cutting element is coupled to the drive in such a way that different segments of the cutter for the execution of a respective cut, can be moved one after the other past the shearing element.

Stapling device with rotary cutting element

The apparatus described in the present disclosure is fitted above a support (30) on which printed products are transported as a scale-like stream (31). It has two measuring points (M.1 M.2) placed at a distance from each other, which scan the surface of the scale-like stream. In the method described in the present disclosure, this apparatus measures the difference in the level of the surface of the scale-like stream between the two measuring points, records it as a measuring signal, and uses it to detect faults in the scale-like stream. The difference of levels is large when there is an edge of a product between the two measuring points and small when both the measuring points are on the stone product, but the total thickness of the scale-like stream in no case affects the difference of level. Typically, the apparatus described in the present disclosure has two contact wheels (11, 21) that run over the surface of the scale-like stream; the first contact wheel is fitted to a pivot arm (13), the second contact wheel (21) is fitted to a lever (23) which in turn pivots on the arm (13), and a sensor measures the amount of the pivot movement of the lever (23).

The chain drive described in the present disclosure, instead of using a single sprocket wheel, saves space by making use of two or more sprocket wheels coupled together by slip-free means, each sprocket wheel having only a small number of low sprockets. The number of sprocket wheels, the center-to-center distance between the sprocket wheels, the tip diameter of the sprocket wheels, and the phase offset of the sprockets as between the sprocket wheels which form a set of such wheels are all so matched that one sprocket of one sprocket wheel always engages in the chain in rhythmical sequence, so that all the sprocket wheels rotate smoothly when the chain moves evenly.

Chain drive

A displacement device is arranged at an input section of a stuffing apparatus for stuffing at least one insert into folded printed products. The displacement device mutually displaces relative to one another two main printed products which have been infed in superposed or mutually reposing relationship upon one another in a predeterminate product conveying direction before these two main printed products are engaged by a transport device and further delivered to an infeed section of the stuffing apparatus. For this purpose, one printed product is fixedly retained by a clamping element controlled by a cam whereas the other printed product is displaced by a displacement or slide element in the product conveying direction. The displacement or slide element is actuated by a drive arrangement comprising an entrainment lever upon which acts a stop or abutment of the transport device during its return motion. The drive arrangement converts the return movement of the transport device into a displacement motion of the displacement or slide element in the product conveying direction.
