Abstract: A device for feeding packaging blanks (3) to a packaging machine has a magazine with two shafts (7) mounted at the bottom for supporting the blanks (3). The shafts (7) are brought to rotate at constant speed in opposite directions to each other, hence eliminating the static friction from the bottom of the magazine. An angle is formed between the shafts (7), so that a small, forwardly directed force component contributes to the movement of the blanks (3). The dynamic friction is used to move blanks (3) towards a gate (2) at the end of the magazine, and only a small, constant feeding force (A) from a pusher is necessary for the movement.

Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.

The support device has a supporting position, wherein the support device supports the sheet and a non-supporting position wherein support for the sheet is removed. A stacking platform is provided below the second location. Control means control the gripper device, the gripper drive means and the support device.

Abstract: Methods and devices for dynamically assigning document parameters to output receptacles of multiple output receptacle document evaluating devices. Documents are directed into individual output receptacles based upon their document parameter or parameters. For example, according to one embodiment a currency evaluating device comprises an input receptacle adapted to receive a stack of currency bills, a plurality of output receptacles, a transport mechanism, and a processor adapted to control the operation of the device. The processor is programmed to determine the denomination of a bill and determine if an output receptacle is associated with the denomination of the bill. If an output receptacle is not associated with the denomination of the bill, the processor is programmed to associate an output receptacle with the denomination of the bill and cause the bill to be transported to an output receptacle associated with the denomination of the bill.

Abstract: An independent motor/reductor drives a conveyance device that feeds a converting press. The converting press includes a number of stations including a feeding station, a converting station, a waste stripping station and a delivery station. The conveyance device services the stations and includes two endless gripper bar chains to convey sheet material through the converting press. A transverse drive shaft drives the conveyance device under the control of the independent motor/reductor. The independent motor/reductor provides motion trajectories for the conveyance device that are independent of, but synchronized with, the serviced stations. The arrangement improves throughput, reduces machine wear and results in a simplified design.

Abstract: A printer paper tray improper loading protection system which is automatically moved by the repositioning of a conventional repositionable stack edge guide to restrict improper loading of sheets into the area of the tray which is outside of the proper sheet stacking area for sheet feeding, even though that restricted area varies depending on the selected size of the sheets being properly loaded within the proper sheet stacking area. A customer warning and partial obstruction of the non-feeding restricted area of the tray eliminates confusion as to where the operator should load paper into the tray whenever the tray is accessed, no matter where the tray stack edge guides are positioned for different paper sizes. An accordion-folded, reeled, or other expandable and contractible member operatively connects between the repositionable stack edge guide and the opposite end of the tray, extending above the tray stacking surface therebetween.
