Abstract: A cutting device and a method for cutting paper are provided. The cutting device includes a cutting blade and a counter-member. The cutting device is further provided with a first guide and a second guide extending in or parallel to the driving direction for linearly guiding a holder that holds the cutting blade. Each of the guides includes a guide body. The guide bodies of the first guide and the second guide, when released, are arranged to be rotatable relative to the frame about a first adjustment axis and a second adjustment axis, respectively. Each guide body includes an eccentric section that moves eccentrically about the respective adjustment axis and that is arranged to convert the rotational movement of the guides about the respective adjustment axes into a linear movement of the holder in the adjustment direction.

Abstract: The invention relates to a cutting device and a method for cutting paper, wherein the cutting device comprises a cutting blade and a counter-member that cooperate to cut the paper along a cutting line, wherein the cutting blade is movable towards and away from the counter-member in a driving direction transverse or perpendicular to the cutting line, wherein the cutting device is provided with a drive mechanism to drive the movement of the cutting blade with respect to the counter-member in the driving direction, wherein the drive mechanism comprises a first spindle and a second spindle, wherein the drive mechanism further comprises one or more motors and a mechanical synchronization element in the form of a chain or a toothed belt that is arranged to synchronize the first spindle and the second spindle in a 1:1 ratio.

Abstract: The invention relates to a device for decurling a web of material, such as a paper web, which device comprises: a first main roller; a second main roller arranged parallel to and at a distance of the first main roller, wherein the first main roller and the second main roller are arranged in a main plane; and a decurling roller arranged parallel to and between the first and second main roller, when viewed in a direction perpendicular to the main plane, wherein the spacing between the first main roller and the second roller is smaller than the diameter of the decurling roller.

Abstract: A folding machine for folding a stack of sheets, the folding machine comprising: a frame; mechanism for pre-folding a stack of sheets along a crease line into a main plane such that a booklet with a straight back is obtained; mechanism for keeping the pre-folded booklet relative to the frame; mechanism for finishing the fold; and a transport plate having a leading edge around which the stack of sheets is folded, the transport plate being movable along the mechanism for pre-folding and the mechanism for finishing the fold.

Abstract: Provided herein is a device for folding a stack of sheets. The device includes a frame, means for pre-folding a stack of sheets along a crease line into a main plane such that a booklet with a straight back is obtained, means for keeping the pre-folded booklet relative to the frame, a carriage movably arranged to the frame and moveable parallel to the back of the booklet, and a nip arranged to the carriage for receiving the back of the pre-folded booklet. The nip direction forms an angle greater than zero with respect to a direction of movement of the carriage.

Abstract: A device for printing simultaneously three dimensional objects includes a support surface for supporting the object to be printed and a carriage arranged over the support surface. The carriage is movable along two axes of a Cartesian coordinate system parallel to the support surface the distance between the carriage and the support surface is adjustable. A number of printing heads are arranged at the carriage. The printing heads are positioned at a regular first pitch distance along the first axis of the Cartesian coordinate system and at a regular second pitch distance along the second axis of the Cartesian coordinate system.

Abstract: The invention relates to a method for folding a stack of sheets, said method comprising the steps of: pre-folding the stack of sheets along a crease line into a main plane such that a booklet with a straight back is obtained; urging a part of the back into a meandering pattern, wherein the meandering pattern is caused in a secondary plane perpendicular to the main plane; and subsequently releasing the part of the back, such that the part of the back may return to a straight back part. The invention further relates to a device for folding a stack of sheets according to this method.
