Definitions
- the invention relates to a device according to the preamble of claim 1 and a method according to the preamble of Claim 6.
- They are for transporting sheet layers suitable, e.g. contiguous over a connection, like an edge connection, hereinafter called fold, with each other are directly connected.
- the sheet layers like paper, then lie against each other with their inner sides and form an outside with facing outer surfaces. If folded, the insides go over the concave Inside of the fold and the outer surfaces over the convex curved outside of the fold in one piece.
- the sheet layers can be on either side of the connection or be multilayer on this. The insides are then through the innermost layer and the outsides through the outermost Location formed. In between there are other layers.
- Such too folding or folded sheets are e.g. to exercise books further processed.
- DE-PS 25 19 420 is a transport and folding device become known, on their characteristics and effects for inclusion in the present invention. With her can also stack thicker sheets without the risk of internal crushing high speed and easy to set up.
- US 1 693 147 describes a folding device with one on one Swiveling arm arranged folding sword that has a front folding edge projecting toothed sections and recessed smooth Has sections.
- the layer to be folded is passed through a folding gap between two transport rollers, which are set down so that they the folded position mainly in the area of the recessed leading edge of the folded sword to contact. This will create an undesirable friction between the Folding sword and, with the folded layer in between, the transport rollers avoided.
- the invention has for its object a device or a method to create, by which this effect is further improved. Although the Leaf layer is removed from the engagement member with little friction or the Working speed should be increased, a perfect folding result sought.
- means are provided by which the sheet layer is so attached to the Conveyor is passed that the shear force acting on the outside not or only insignificantly or negligibly on the engaging member is transmitted.
- This transverse force expediently acts on everyone Leaf layers so clamping that they do not oppose each other under the Can shift conveying force, the direction of which is transverse to the transverse force.
- the Sheet layers become only by frictional intervention in the outside transported. The transfer of the frictional pressure to the contact between Leaf position and engagement member is significantly reduced or eliminated.
- the force attack for feeding the sheet layer into the conveying engagement can be in the area an opening or interruption of the engagement member also upstream from Conveyors are made on the outside.
- this opening is useful on Provided end of the engagement member as an open cutout in the area in which the conveyor engages in the outside of the sheet layer. This presses the conveyor the sheet layers with their insides in the opening immediately against each other and not against the engaging member.
- the training according to the invention is useful wherever sheet layers to be removed from an engagement member with reduced friction. Regardless of the training described, it is also advantageous to like the conveyor is pressing and running on the outside of the sheet layer form the attacking member so that its in the transport or running direction front area exerts the greatest pressing force. Immediately behind it subsequent areas of the pressing surface exert a lower pressing force, e.g. while the pressing surface rolls on the outer surface of the sheet layer.
- the Transverse displacement of the conveyor, the pressing surfaces or the like electronic or hydraulic or pneumatic Control means conceivable, but mechanical are expedient Control means provided.
- These can be a cam control include. Those guided on the cam or cam bodies Runners are connected to each other via transmission drives controlling link connected to the drive.
