Abstract
A zig-zag folding apparatus includes a slitter blade which forms one or more longitudinally extending slits completely through a comparatively wide web of paper thus forming two or more individual, narrower sections of paper. A spreader device, located downstream from the slitter blade, is effective to produce a longitudinally extending gap or space between the individual paper sections where the slits were formed, and these separated paper sections are each transferred to an individual folding mechanism to form individual stacks of zig-zag folded sheets.
Claims25
Apparatus for zig-zag folding a web of paper having longitudinally spaced, transverse perforations, comprising:
- cutter means for cutting the web of paper longitudinally to form at least two side-by-side, longitudinally extending sections of paper;
- spreader means, located downstream from said cutter means, for moving said paper sections apart to form a longitudinally extending gap therebetween;
- folding means for folding each of said paper sections into a separate stack of zig-zag folded sheets.
The apparatus of claim in which said folding means includes a separate folding device for each of said sections of paper, each of such folding devices comprising:
- longitudinally spaced, first and second folding stations;
- a spiral located at each of said first and second folding stations which is effective to fold one section of paper along the longitudinally spaced perforations thereof to form zig-zag folded sheets;
- support means for supporting each side edge of said one section of paper in the course of forming said zig-zag folded sheets.
Apparatus for zig-zag folding a web of paper having longitudinally spaced, transverse perforations, comprising:
- cutter means for cutting the web of paper longitudinally to form at least two side-by-side, longitudinally extending sections of paper;
- spreader means, located downstream from said cutter means, for moving said paper sections apart to form a longitudinally extending gap therebetween;
- folding means, associated with each of paper sections, for folding said paper sections into separate stacks of zig-zag folded sheets, each of said folding means including:
- (i) longitudinally spaced, first and second folding stations;
- (ii) a spiral located at each of said first and second folding stations which is effective to fold one section of paper along the longitudinally spaced perforations thereof to form zig-zag folded sheets;
- (iii) support means for supporting each side edge of said one section of paper in the course of forming said zig-zag folded sheets.
A method of zig-zag folding a web of paper having longitudinally spaced, transverse perforations, comprising:
- cutting the web of paper to form at least two side-by-side, longitudinally extending sections of paper;
- separating the sections of paper to form a longitudinally extending space therebetween;
- folding each of said sections of paper to form at least two stacks of zig-zag folded sheets.
