Abstract
A method for folding sheet-like copies, respectively, made up of a plurality of copy layers, whereby open ends and closed folding spines are formed on the copies by folding operations, which comprises forming the folding spine on the inner copy layers of the copy in a manner that the folding spine is interrupted by non-folded sections; a device for performing the method; a folder for performing the method; and a folding copy foldable by the method.
Claims17
A method for folding a sheet-like multilayered folding copy made up of a plurality of copy layers, the copy being formed by folding operations with an open end and a closed folding spine, the method comprises:
- providing folding components including a pair of folding rollers and a folding blade acting linearly on the copy layers of the multilayered folding copy;
- providing the folding rollers with surfaces being interrupted by recesses distributed along a direction of the folding spine;
- providing the folding blade with recesses formed therein in a region of a folding edge, the recesses of the folding blade having positions coinciding with positions of the recesses of the folding rollers;
- and
- forming the folding spine with longitudinally folded sections interrupted by non-folded sections.
A device for folding a sheet-like multilayered folding copy made up of a plurality of copy layers, the copy being formed by folding operations with an open end and a closed folding-spine, the device comprising:
- folding components for producing the folding-spine on the multilayered folding copy, said folding components including a pair of folding rollers and a folding blade provided for acting linearly on the copy layers of the multilayered folding copy;
- said folding rollers having surfaces for forming the folding spine on the copy layers of the multilayered folding copy, said surfaces being interrupted by recesses distributed along a direction of the folding spine for forming the folding spine with longitudinally folded sections interrupted by non-folded sections;
- and
- said folding blade having a folding edge and recesses formed therein in a region of said folding edge, and said recesses of said folding blade having positions coinciding with positions of said recesses of said folding rollers.
A folder for folding a sheet-like multilayered folding copy made up of a plurality of copy layers, the copy being formed by folding operations with an open end and a closed folding-spine, the folder comprising:
- folding components for producing the folding-spine on the multilayered folding copy, said folding components including a pair of folding rollers and a folding blade provided for acting linearly on the copy layers of the multilayered folding copy;
- said folding rollers having surfaces for forming the folding spine on the copy layers of the multilayered folding copy, said surfaces being interrupted by recesses distributed along a direction of the folding spine for forming the folding spine with longitudinally folded sections interrupted by non-folded sections;
- and
- said folding blade having a folding edge and recesses formed therein in a region of said folding edge, and said recesses of said folding blade having positions coinciding with positions of said recesses of said folding rollers.
