Abstract
An interfolding machine for sheet material for making a stack of interfolded sheets includes at least one web of material to interfold that is cut into sheets of predetermined length and rolls for partially overlapping the sheets in order to form an overlapped portion between two consecutive sheets. Interfolding rolls are also provided, adapted to produce the stack, as well as a conveyor adapted to convey the partially overlapped sheets in a zone set between the roll and the interfolding rolls. Further, the overlapping portion of the sheets is maintained constant through a plurality of belts and guides facing the belts so that between the belts and the respective guides a channel is formed for conveying the partially overlapped sheets.
Claims8
Interfolding machine of sheet material for making a stack of interfolded sheets, comprising:
- at least one web of material to interfold that is cut into sheets of predetermined length;
- means for partially overlapping said sheets in order to form an overlapped portion between two consecutive sheets, where said overlapped portion is a predetermined fraction of said sheet length;
- means for interfolding the sheets to form the stack;
- means for conveying the partially overlapped sheets in a zone set between said means for partially overlapping and the means for interfolding, and
- means for keeping constant the overlapped fraction of the sheets between said conveying means and the interfolding means.
