A folding device for a flat blank has a plurality of bearing blocks arranged in a row in a first direction, the mutual distance of which can be changed by a drive device and each of which has a support surface for the blank by a holding device. A plurality of folding blades are arranged at a distance next to one another in the first direction, at least one of the folding blades being arranged between immediately adjacent bearing blocks. The folding blades can be adjusted by changing a mutual distance with an additional movement component perpendicular to the blank. Adjacent bearing blocks are coupled in terms of movement via a linkage. The folding blade arranged between adjacent bearing blocks is connected to the linkage so a change in distance between the bearing blocks can be transferred by the linkage to the folding blade for the adjustment thereof.

The invention relates to a folding machine for folding an object, using a measurement system for measuring an angle between a first plane through a first surface area and a second plane through a second surface area of an object. The system includes a sensor arrangement for measuring the coordinates in a measurement coordinate system of a plurality of measurement spots in the first surface area, and an inclinometer for measuring an inclination of the measurement coordinate system to the direction opposite to the direction of the force of gravity. The measurement system also includes a processing device for determining the angle between the first plane and the second plane based on the measured coordinates of the plurality of measurement spots, the measured inclination and information on the angle between the second plane and the direction opposite to the force of gravity.

A bending system for separating a page from a cover of a value document, wherein the page is connected to a spine of the cover, the spine separating the cover in first and second cover potions, wherein an angle γ is formed between the first and second cover portions. The bending system includes a bending unit connected to a motor, wherein the motor is configured to operate the bending unit such that the bending unit bends the value document to a first state, where γ is larger than 180°, and then back to a second state, where γ is at least 180° but less than γ in the first state, to separate the page from the cover. Also disclosed is an engraving system for engraving a front side and backside of a page of the value document and a document manufacturing device including the bending system and engraving system.

Disclosed is a device for folding sheets, the device provided with two transport belts positioned opposite each other in such a way that sheets can be clamped between the transport belts with the exception of a protruding part that protrudes between the transport belts, whereby the device is provided with two slats that extend along the transport belts and between which the protruding part can slide so a strip protrudes between the slats, whereby the device is also provided with one or more folding elements along the transport belts that can fold the abovementioned strip over or around a slat to form a fold line and whereby the device is such that it guides the sheets with their strip along the folding elements and the slats by the driver of the transport belts.

A stretching and bending mechanism 3, fixes a resin sheet material 2 by a first fixed clamp and a second fixed clamp at both sides of a center of a transverse direction of the resin sheet material 2 at each end in a longitudinal direction of the resin sheet material 2, and when transverse guides 13 are bent between the first and second fixed clamps 9a, 9b, at least one of the longitudinal guides 15 is guided by the bending guide 16 so as to move toward the center side in the transverse direction.

Apparatus and methods are provided for folding discrete items such as diapers at high speeds. Discrete items are conveyed in a machine direction toward a pair of engaging members rotating in the machine direction and first carrying a top side of a leading edge of the discrete item with a first engaging member away from the conveyor, and then carrying a bottom side of the leading edge with a second engaging member back towards the conveyor. The diaper fold is created at a contact point with a folding finger which travels rotationally and straight in a fixed orientation about a travel path into and out of contact with the diaper.
