摘要： A machine for producing packages of folded or interfolded laminar products made of paper, in particular packages of napkins, tissues, towels, or similar products, comprising a folding or interfolding group, equipped with a first and a second folding or interfolding roll configured to fold or interfold a plurality of sheets of paper, and to obtain a stack of folded or interfolded sheets, according to a predetermined folding or interfolding configuration, which grows in height along a vertical forming direction. The machine comprises, furthermore, a separation group configured to separate a completed stack of folded or interfolded sheets, once that a predetermined height of said stack being formed is reached, from a following stack being formed. A transfer group is, furthermore, provided configured to transfer the completed stack on a discharge device configured to discharge the completed stack from the machine.

摘要： A folding or interfolding unit of a plurality of sheets of paper comprising a first and a second folding or interfolding roll to fold, or interfold, the plurality of sheets of paper according to a predetermined folding or interfolding configuration, at a folding or interfolding zone. Each folding or interfolding roll comprises a tubular body which rotates about a longitudinal rotation axis oriented along a horizontal direction and a plurality of gripping groups integral in rotation with the tubular body. Each gripping group comprises a mechanical gripping member configured to move, at a gripping point, from a releasing configuration to a gripping configuration, where is arranged to mechanically hold the, or each, sheet up to a releasing point having a second angular position.

摘要： A folding or interfolding unit includes first and second folding or interfolding rolls to fold or interfold the sheets of paper according to a predetermined folding or interfolding configuration. The first and second folding or interfolding rolls include, respectively, a tubular body configured to rotate in a predetermined direction of rotation about a longitudinal rotation axis, and gripping groups, each of which includes a mechanical gripping member configured to move, at a gripping point, from an opening position to a closing position, which is arranged to mechanically hold the sheets up to a releasing point. Each gripping group includes at least one suction hole associated to each mechanical gripping member. A vacuum distribution device selectively pneumatically connects at least one suction hole at a time to a device for generating a predetermined vacuum degree, to cause the sheets of paper to adhere between starting and ending positions.
