  • Patent number: 4805894
    Abstract: Methods and apparatus for stacking predetermined sheets of various intermixed sizes in a stacking location by advancement of stacking devices into that location, selectively guide further sheets past the stacking location. That guiding of further sheets past the stacking location is mechanically slaved to the advancement of the stacking devices into the stacking location. Where the stacking devices are withdrawn from the stacking location preparatory to each stacking of a predetermined sheet, the guiding of that predetermined sheet into the stacking location is mechanically slaved to such withdrawal of the stacking devices. Where the sheets are stacked against a movable wall, an unobstructed space for receiving each sheet guided to the stacking location is permanently preserved between the movable wall and the withdrawn stacking devices.

  • Patent number: 4723773
    Abstract: Sheet feeding systems provide a sheet receiving nip at a peripheral region of a rotary sheet transport and arrange sheets in a stack having a stack and formed by a bottom sheet and spaced from the nip by a distance shorter than the minimum length of any of the sheets. The stack is temporarily lifted from a stack rest, and the bottom sheet is removed therefrom. Sheet jams are prevented by advancing any bottom sheet to the rotary sheet transport in a plane intersecting that rotary sheet transport at a distance from the nip. Each bottom sheet is further advanced from that intersecting plane to the nip, and such advanced bottom sheet is engaged with the nip for transport away from the stack with the rotary sheet transport. The stack end is returned to the stack rest after said removal of a bottom sheet, and the temporary stack end lifting, sheet advancing, sheet engaging and stack end returning steps are repeated individually for further bottom sheets advanced from the stack end.

  • Patent number: 4707917
    Abstract: Objects are received between first and second cutting elements of a cutter, which is suspended via the first cutting element from a rod-like object to be cut. The first cutting element, which preferably is formed as a cutter suspension including a cutting blade, is moved into the rod-like object toward the second element, until that object has been cut. The cutter preferably is mounted on an elongate handle, and rotary motion of such handle is translated into movement of the cutting elements toward each other. A quick release mechanism permits quick release action of the second element and an elongate member permits holding of the first cutting element onto the object, while the second element is pushed with the elongate handle toward the object.

  • Patent number: 4431179
    Abstract: Service access to a transport channel is facilitated by providing a corner for receiving a margin or seam of a wall of the transport channel. A bias is exerted on the margin for pushing such margin into the corner and releasably biasing the wall into a position in which it laterally contains the transport channel. The bias is such as to permit manual tilting of the wall away from the transport channel for service access. After termination of such tilting, the bias restores the wall to its normal position at the transport channel.

  • Patent number: 4257324
    Abstract: Methods and apparatus for ascertaining movement of a device from a first position to a second position couple a ratchet member and pawl combination to that movable device. Clicks indicative of the movement of the device are generated by effecting relative motion between the ratchet member and pawl in accordance with the movement of the device from the first to the second position. An ascertainment is then made from the generated clicks whether the movement of the device has in fact resulted in the desired movement from the first to the second position. The invention is of particular utility in the monitoring of character segments in printing devices, but is not limited to such an application.
