STRUCTURE OF MULTIPURPOSE SHEET FOLDING AND STACKING MACHINE
First Claim
1. Folding and stacking machine, for making packages of folded and stacked sheets starting from a web of paper, or similar material, comprising:
- a folding section comprising a first and a second folding roller, said first and second folding rollers adapted to fold said sheets into a plurality of panels and to form a stack of folded sheets;
a sheet feeding section for feeding sheets to said folding rollers, said sheet feeding section comprising a first sheet feeding means that is adapted to feed a first plurality of sheets to said folding rollers along a first feed line and a second sheet feeding means, that is distinct from said first sheet feeding means and that is adapted to feed a second plurality of sheets to said folding rollers along a second feed line,characterised in thatupstream of said sheet feeding section one sheet supply section is provided for unwinding and conveying a single web of paper according to a feeding direction, in that one cutting section is provided that is adapted to cut said web of paper, coming from said feeding direction, into sheets of paper having a determined length L, and in that a means is provided for distributing alternatively, and selectively, said sheets of paper to said first sheet feeding means for creating said first plurality of sheets and to said second sheet feeding means for creating said second plurality of sheets.

Abstract
A folding and stacking machine of a web of paper has first and second feed lines. The machine also has a folding section with folding rollers having a linear folding speed, VP. The folding rollers are adapted to receive a plurality of sheets of length L that can overlap each other for a fraction Y of their length L and to fold them into a plurality of panels P. The machine also has rollers adapted to feed at the folding speed VP the series of cut sheets but not yet folded towards the folding rollers. The rollers are located at the confluence of the two sheet feeding lines. Upstream of the first and feed lines a single cutting section is provided to cut a web of paper that proceeds along a direction of movement at a speed V(1).
