A rack display comprising a base having a front panel with a plurality of horizontal and vertical slots included thereon; left and right side panels extending from sides of the front panel; a back panel extending between the left and right side panels; and one or more shelf members including horizontal and vertical tabs. The shelf members are secured to the base by inserting the vertical and horizontal tabs within the vertical and horizontal slots respectively. The rack display is erected from a knockdown configuration by securing the shelf members to the front panel of the base via insertion of the horizontal and vertical tabs within the horizontal and vertical slots respectively.

A fold-enhancing device includes a pressing member, at least one retaining member, and a moving mechanism. The pressing member presses against a fold line of a recording-medium bundle folded into a booklet shape. The recording-medium bundle is obtained by stacking multiple sheets of recording media. The retaining member retains the recording-medium bundle and is provided at a position located away from the fold line in a direction intersecting the fold line and not in contact with the pressing member. The moving mechanism moves the pressing member and the retaining member in a direction extending along the fold line.

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 method in which, while an article is carried with a main portion in contact with a carrying surface and a to-be-folded portion in contact with a folder plate, includes: a first guiding step, wherein a first guide surface guides the to-be-folded portion of the unfolded article, on a side of the carrying surface, in parallel to the carrying surface; a second guiding step, following the first guiding step, wherein a second guide surface, while being in contact with the to-be-folded portion, gradually raises the to-be-folded portion while moving downstream; and a third guiding step, following the second guiding step, wherein a third guide surface guides the to-be-folded portion so that the to-be-folded portion is folded onto the main portion.

A sheet sticking apparatus includes a feeder configured to feed an adhesive sheet, a folding unit configured to fold the fed adhesive sheet, and an attaching unit configured to press the folded adhesive sheet onto an adherend to stick the adhesive sheet to the adherend. The adhesive sheet includes a first sheet and a second sheet having a feeding-direction leading end temporarily attached to a feeding-direction rear end of the first sheet. The folding unit includes a deflecting section configured to deflect the second sheet into a reverse V-shape.

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.
