Abstract
A stack-like arrangement of printed products with folded edges, in which arrangement the printed products are all arranged with identical orientation, has an increased stability, if it comprises stack sections, within which the folded edges of the printed products indeed lie on top of each other, but wherein the stack sections are arranged displaced in relation to each other, such that the stack sections with folded edges protruding from the arrangement alternate with stack sections with edges opposite the folded edges protruding from the arrangement.
Claims18
A stack-like arrangement comprising a plurality of flat objects, wherein each of the plurality of flat objects has a first edge and a second edge opposite the first edge, wherein the plurality of flat objects are arranged transverse to a stack height and parallel to each other and adjacent to each other, wherein the first edge of each of the flat objects is oriented on a same stack side, wherein the stack-like arrangement comprises a plurality of stack sections, wherein each of the plurality of stack sections comprises at least one of the flat objects, wherein in stack sections comprising two or more flat objects the first edges of the flat objects in such stack sections lie on top of each other, and wherein the stack sections are arranged transverse to the stack height with the first edges of the flat objects in each stack section displaced relative to the first edges of the flat objects in an adjacent stack section such that in alternating stack sections the first edges or the second edges protrude out of the stack-like arrangement.
A method for forming a stack-like arrangement from a plurality of flat objects, wherein each of the plurality of flat object comprises a first edge and a second edge opposite the first edge, the method comprising the steps of
- feeding the flat objects with their first edges in identical orientation;
- arranging the flat objects in a stack-like arrangement substantially transverse to a stack height and parallel to each other and adjacent to each other;
- displacing, on a feeding-side-end of the stack-like arrangement, added stack sections, which each comprise at least one of the fed flat objects and for added stack sections which comprise two or more fed flat objects have the first edges of such two or more fed flat objects lie on top of each other, in relation to each other transverse to the stack height and transverse to the first edges, and thereby alternately adding stack sections with protruding first edges and stack sections with protruding second edges to the stack-like arrangement.
A device for forming stack-like arrangements of flat objects, which device comprises a feeder for feeding the flat objects, a stacker for stacking the fed flat objects and a conveyor for conveying away the stack-like arrangements, wherein the device further comprises a movable displacement means for forming a displacement between neighboring stack sections.
