In a device for loading a feeder rack ( ) in further-processing machines such as gather-stitcher machines or gathering machines ( ) for folded sheets ( ), sheets, booklets or similar printed products, which has a first conveyor arrangement ( ) extending in planar manner for the purpose of feeding printed products ( ) standing on their edges in the form of a horizontal stack ( ), a second, initially upwardly sloping conveyor arrangement ( ) for drawing the printed products ( ) off the stack ( ) in an overlapping formation and for transferring the overlapping stream ( ) to the feeder rack ( ), infinitely variable drives ( ) associated with the two conveyor arrangements ( ), and a light barrier ( ) arranged in the feeder rack ( ), a control means ( ) is provided by means of which the drives ( ) can be controlled in dependence on the degree of coverage (BG) of the light barrier ( ), as a result of which the fill level of the feeder rack ( ) remains at an at least substantially constant height determined by the position of the light barrier ( ). This improves the transfer of the printed products ( ) to the feeder rack ( ).

Device for loading a feeder rack

The set-up procedure for a bookbinding machine is accomplished through the use of a portable computer with an integral data transceiver. Adjustable machine element position information is entered into the portable computer and transmitted to the machine control via a wireless data link and an operator/machine interface. Actual machine element position is sensed and transmitted to the portable computer where it is displayed. Using the portable computer and data link, the operator may serially proceed from one functional machine station to the next to perform the set-up.

Format adjustment apparatus and method for bookbinding

An improved computer-automated control system for a book-binding machine which provides for emergency manual control of the binding machine in the event of failure of the computer-controlled portion of the control system. The improvement includes a manually operated control instrument and a plurality of switchable coupling components associated with the adjusting devices of a book-binding machine. Each of the switchable coupling components is electrically coupled to an associated adjusting device and the computer-automated portion of the control system and is capable of being electrically coupled to the control instrument. Upon coupling of the control instrument to the switchable coupling component, control of the associated adjusting device is switched from the computer-controlled portion of the control system to the control instrument.
