Abstract: The invention relates to a device for feeding book blocks, books or similar printed products (2), in step with the working cycle, to a subsequent processing machine. The infeed device comprises a continuous-drive accumulating conveyor (3); an arrestor (5), arranged at the downstream end of the continuous-drive accumulating conveyor (3), for cycled release of individual printed products (2); and a continuous-drive onward conveyor (11), which transports the printed products (2) by means of frictional force, for onward conveying of the separated printed products (2) to a defined transfer position (13) from which the printed products (2) are taken over, in step with the working cycle, by an infeed system (17) of the subsequent processing machine.

Abstract: In a device for loading a three-knife trimmer with brochures, periodicals or like bound book blocks (1), comprising a feed conveyor (4), a stacking device (16) operable in magazine mode and counted stack mode and including a magazine (17) having a first upper magazine intermediate shelf (18) and a second lower magazine intermediate shelf (25), and comprising a delivery table (28) arranged below said magazine (17) and an ejector (29) for cyclically and synchronously feeding a stack (3) of book blocks to the intake device (35) of the three-knife trimmer, it is provided that the feed conveyor (4) is formed by a conveyor belt (5) continuously driven at a first velocity (vS) and by an accelerator conveyor (6) located directly downstream thereof in the feed direction and driven at a higher velocity (vB), and that a separating device (11) for book blocks (1) supplied in an imbricated flow (2) is arranged in the transition zone from the conveyor belt (5) to the accelerator conveyor (6) for holding back a following po

Abstract: The invention relates to an apparatus for electronic monitoring of the supply current of modules connected to a bus, in particular for monitoring the supply current of bus devices of an automation bus system. The object of the invention is to provide an apparatus for electronic monitoring of the supply current of modules connected to a bus, which on the one hand, if required, carries out reliable isolation from the supply voltage, and simultaneously maintains the diagnostics capability for the purpose of fault locating. The invention achieves this by virtue of the fact that the apparatus has at least one device for detecting and at least one device for limiting and/or disconnecting the supply current.

Abstract: An input/output module (1) with a terminal unit (2) for connection of sensors or actuators with an electronic unit (3) and with a bus connection element (4). The terminal unit (2) has at least one input/output (5) located in a surface thereof and the terminal unit is connected by the electronic unit (3) to the bus connection element (4). To replace the electronic unit (3), the terminal unit (2) can be removed from the electronic unit (3) without the need to remove lines (6) connected to the inputs/outputs (5). The terminal unit (2) is able to be mounted to the electronic unit (3) in each of two positions, the input/output (5) in the two positions lying in planes that are offset relative to each other by 90.degree..

Abstract: An adhesive film which reliably completely covers the spine side of a book block, prior to mating with a cover, is applied by an applicator roller which is controlled to rotate at speeds which are a function of the book block linear velocity and the location of the book block relative to the roller. The applicator rotational speed is determined from stored information and, depending on book block location, will either be greater or less than book block velocity.
