The invention relates to a device and a method for collecting successively fed flat objects, in particular sheets. The device contains a blocker having at least one movable blocking element for stopping and subsequently releasing a certain number of objects fed, wherein the blocking element is a rotational body rotatable by a motor around its middle axis which, at its exterior periphery, has at least one reception for stopping the front edges of the objects fed in an idle position of the rotational body and for its deflection when turning the rotational body, and wherein at least one transport element for advancing the objects deflected when turning the rotational body is associated to the rotational body.

A method and a device for transferring at least two sheets, which are arranged in a shingled mode of arrangement in a sheet transport direction, to a sheet handling machine in which the at least two sheets are moved at a first speed after the transfer, a first and a second sheet being spaced by a certain length of displacement in the sheet transport direction. The two sheets are first supplied to the sheet handling machine at a second speed which is higher than the first speed. As soon as the first sheet is decelerated to the first speed in the sheet handling machine, the second sheet is decelerated to a third speed which is lower than the second speed.

A device for producing a scaled stream with a controllable scaled-stream thickness has a sheet guiding device for receiving therein a stack of sheets, a first transport means, which has a selectively operable or controllable drive, which engages only the lower surface of the stack of sheets and which is arranged relative to the stack of sheets in such a way that the stack of sheets rests thereon with at least a first part of its weight, a second transport means, which is arranged behind the first transport means when seen in the direction of the stream of sheets, which is arranged relative to the stack of sheets in such a way that, when the second transport means is operated without operating the first transport means, it will transport only sheets which have already been drawn out of the stack of sheets by the first transport means, and which is also arranged relative to the stack of sheets in such a way that the stack of sheets rests thereon only with a second part of its weight, the second part of its weight being small in comparison with the first part; a scaled-stream thickness detection device for detecting the scaled-stream thickness, which operates or controls the drive of the first transport means in response to the detected scaled-stream thickness.

A paper handling system including a gathering path and a plurality of paper handling units. The (114 to 138), said gathering path is defined by a plurality of essentially corresponding modules (102, 200), each of said modules (102, 200) being provided with a collect box (104, 210), a transfer bridge (212) for effecting supply in the direction of transport (106, 202), at least one transfer bridge (214, 216) for effecting supply in a direction transversely to the direction of transport, and a discharge unit (300).

The invention relates to the construction and arrangement of wall components which are to be attached to the posts and spars of a basic frame for machines, instruments, equipment and the like. These wall components extend from the middle of one post to the middle of another and are supported on the upper faces of the posts and the spars between them by their folded upper web. The side edges of the web extend to approximately the middle of the face of the post and then run obliquely inwards. A section covering the posts at the top is recessed where the web is supported. Running around the inside edge of the wall component there is a frame-like spacer, the depth of which determines the distance by which the outer wall of the wall component projects beyond the outside of the post.

The present invention relates to a method and a device for distributing a predetermined number of sheets (410, 412, 414, 416) from a group of sheets in which a plurality of sheets is arranged in a shingled mode of arrangement in a sheet transport direction (P) in such a way that the leading edges of the sheets in the paper transport direction are spaced apart by a certain length of displacement (X), wherein the group of sheets is moved in the sheet transport direction (P) by a predetermined distance which depends on the number of sheets to be distributed and on the sheet displacement, a respective sheet constituting the leading sheet in the sheet transport direction (P) being distributed from the group of sheets as soon as the respective leading sheet has reached a distributing unit (504) as a result of the movement.

The present invention pertains to a collecting device for sheets 3 for forming stacks of sheets 6 from individual sheets 3 fed in at a stop 26, as well as with a removing device 28 for the stacks 6 formed. To remove the stacks of sheets 6 with a high reliability of operation, the present invention provides for a movable stop 26 and a driven roller arrangement 29, 30, 31, which is mounted such that it can be fed to the stack of sheets 6. On the other hand, the present invention discloses a special, elastic conveying means 8, 11, which guides the sheets 3 onto the stack of sheets 6 along a transport path 7 and over a deflector 16. Both measures can be embodied both as a combination and separately.

A stacked-sheet prefeeder comprises a sheet guiding device for receiving therein a stack of sheets, an intermediate tray, a scale former for removing sheets, arranged in a stack and/or in a scalelike mode of arrangement, jointly from the lower surface of the stack received in the sheet guiding device and for introducing these sheets into the intermediate tray in a first direction of movement, a sheet separator for removing from the intermediate tray the respective lowermost sheet as a single sheet in a second direction of movement which is substantially opposed to the first direction of movement, and a guide means arranged in the intermediate tray and used for guiding the sheets in the intermediate tray at their sheet edges constituting the front sheet edges in the second direction of movement, the guide means being implemented as a transport and guide means in such a way that it moves the sheet edges constituting the front sheet edges in the second direction of movement in the interior of the intermediate tray to the sheet separator.

A knife folder for folding a sheet material comprises a sheet-material feeder for feeding the sheet material in a first direction, a folder for folding said sheet material, and a sheet-material conveyer used for conveying the sheet material and comprising at least one pair of rotating conveying components whose axes of rotation are arranged in a second direction substantially at right angles to the first direction. The folder pushes the folded sheet material between the conveying components of the at least one pair of conveying components when it is at its folding position. The sheet material is advanced up to a stop. The folder comprises a knife extending in a third direction substantially at right angles to said first and said second direction. The sheet material can be conveyed in the third direction by actuating the conveying components.
