The inventive composition (3) contains an anti-static agent and a lubricating agent. A flat object (2) with a surface which has been treated with this type of composition acts as a predetermined separation point in a plurality of such objects arranged at least partially in a pile. The lubricating agent reduces the friction coefficient between the treated surface and the surface of the next object and therefore reduces the static friction between the two objects. The anti-static agent reduces the static charge of the objects in contact with each other and therefore also reduces the bond which can be produced between these objects by static charging. These two effects ensure that in a plurality of flat objects which are arranged on top of one another and are statically charged by means of a field of direct current, a displacement force (11) from a component parallel to the main surfaces of the objects produces a displacement at the point of the treated surface.

According to the invention, a static charge is produced on the surfaces of the flat objects (2) arranged on top of each other by guiding said objects (2) through a field of direct current oriented essentially vertically to their main surfaces. This charge creates electrical forces of attraction between the surfaces of the objects and these electrical forces of attraction increase mutual bonding. This effect caused by static charging of the surfaces of flat objects arranged on top of each other is reduced or prevented for at least one or two surfaces forming a predetermined separating point, by treating this surface or these surfaces in advance with an anti-static agent (3). No concentration of charge can be built up on the treated surface or any concentration of charge which does build up is compensated very quickly, so that there is no increase in bonding at the separating point or the bonding is much slighter than between the surfaces which are not part of the separating point. Consequently, the objects at the separating point can be moved against each other with less force. The inventive method is particularly suitable for opening multi-surface printed products at specific points.

The production of offset stacks of business forms is effected in a continuous (i.e., without interruption) manner until a vertical stacker (13) into which the forms (39) are fed is full. Between a detacher (11) and the stacker (13), the forms are automatically and continuously directed either to the left or the right from a common center line to offset the forms into different groups with at least one form in each group. This offsetting action may be accomplished by a pair of angled conveyor belts with steel balls movable into and out of association with the conveyor belts by solenoids, and/or by two sets of diverter wheels which are also angled and which are moved up out of engagement with the forms or down into engagement with them.
摘要:
A device for manufacturing sheets for the purpose of mass-producing sheet pallets made of synthetic resin through a simple process and with high productivity, comprising a first process (1001) for feeding material of sheet in a specified shape and having corner parts, a second process (1002) for cutting at least said corner parts and forming a sheet in a desired shape, and a third process (280) for storing said sheets thus made up.

An image forming apparatus includes image forming means (1) configured to form an image onto each sheet, ejection means (5) on which the sheet with the image formed by the image forming means is ejected, sorting means configured to sort the sheets to be ejected on the ejection means into subsets, and control means (7) configured to, when executing a mode for forming images on first sides of sheets, ejecting the sheets with the images on the first sides, and forming images on second sides of the ejected sheets manually placed on sheet feeding means for second-side image formation, control the sorting means to sort the sheets ejected on the ejection means after first-side image formation into subsets so that the number of sheets in each subset does not exceed a maximum number of sheets stackable on the sheet feeding means.
摘要:
A sheet processing device with which sheets may be deposited in a staggered configuration relative to one another, comprising a paper path (11), a first and second sheet edge guide (12,13) fitted substantially parallel to one another in the feed-through direction, and a transportation device (10) arranged to convey a sheet through the paper path (11) in the feed-through direction and the lateral direction, where the first and second sheet edge guides (12,13) are arranged statically relative to the paper path (11) and in a staggered configuration relative to one another in the lateral direction, and a switchable control mechanism (16) has been fitted able to adopt a first and second configuration, allowing a sheet edge to be conveyed into the first and second sheet edge guides respectively during operation.
