Abstract: A feed device for stacks of paper or plastic material has at least one transport unit with a supporting member for the stack and at least one transport element. A separating unit with at least one rotatably driven feed drum is provided for removing individual sheets from the stack. The transport unit transports the stack to the separating unit and is pretensioned in the transport direction toward the feed drum such that the stack rests with pretension against the feed drum. The pretension can be provided by a spring acting on the transport unit.

Abstract: An inserting device has at least one transport device having at least one first transport element for transporting envelopes. At least one downstream station is arranged downstream of the at least one transport device. The envelopes are supplied to the at least one downstream station such that the envelopes are deposited in the at least one downstream station in an overlap arrangement. The overlap arrangement can be an imbricated arrangement or a stacked overlap arrangement. An inserting unit is arranged downstream of the at least one downstream station, and the envelopes are supplied to the inserting unit in the overlap arrangement.

Abstract: A transfer device for an inserting device is rotatable about an axis of rotation extending transversely to a feed direction of articles being fed to the transfer device. The transfer device has at least one receptacle for the articles. At least one transport unit for transporting the articles away in a transport direction transverse to the feed direction is provided. A central shaft for driving the transport units is provided.

Abstract: A reloading device for stacks of sheets of paper or plastic has at least one receptacle for receiving a stack and at least one support onto which the stack is placed. At least one peeling device is arranged at a bottom end of the at least one receptacle, wherein the peeling device is configured to move transversely to the stack and, when moving transversely to the stack, to peel in a peeling step at least one sheet from a bottom end of the stack. The peeling device is preferably a peeling blade.

Abstract: A device for enveloping inserts in an envelope has at least one feeder for supplying first and second articles. A transporting device for the first and second articles received from the at least one feeder is arranged downstream of the at least one feeder. A first adhesive station with at least one applicator unit is configured to apply an adhesive onto the first article provided for forming an envelope, wherein the envelope is produced from the first article without waste. The at least one applicator unit is stationary during application of the adhesive onto the first article.

Abstract: A web and sheet sluice adjustable to different material thicknesses for sheets of paper or the like, which are fed to a processing or treating unit. The sluice has a passage gap between a friction roller, which rotates continuously during the working operation, and an axially parallel braking roller, which is radially adjustable in relation to the friction roller. An electric switching element sends a control signal for an electric circuit during the adjustment of the passage gap to the thickness of a sample located in the passage gap. The braking roller is rotatably mounted on the cylindrical eccentric of an eccentric shaft, which can be driven by a first electric motor drive and can optionally be adjusted to both directions of rotation, and with the friction roller stationarily stopped, it can be driven by a second electric motor drive at a speed of rotation that is substantially higher than the velocity of adjustment of the braking roller via a driving gear which can be moved out of its normal position.
