Abstract
The shingling device comprises: a shingling conveyor, adapted to receive a stream of sheets aligned with one another and not overlapping; a braking device, positioned above the shingling conveyor and configured to slow down the sheets arriving to the shingling conveyor, and to partially overlap the incoming sheets in shingling fashion. The braking device comprises: a first set of braking wheels aligned with one another along a first rotation axis orthogonal to a feed direction of the sheets to the shingling conveyor; and a second set of braking wheels aligned with one another along a second rotation axis orthogonal to the feed direction of the sheets to the shingling conveyor.

A shingling device for partially overlapping the sheets of a stream of sheets in shingling fashion;
- the device comprising:
- a shingling conveyor, adapted to receive a stream of sheets aligned with one another and not overlapping;
- a braking device, positioned above the shingling conveyor and configured to slow down the sheets arriving to the shingling conveyor, and to partially overlap the incoming sheets in shingling fashion;
- wherein the braking device comprises:
- a first set of braking wheels aligned with one another along a first rotation axis orthogonal to a feed direction of the sheets on the shingling conveyor;
- and a second set of braking wheels aligned with one another along a second rotation axis orthogonal to the feed direction of the sheets on the shingling conveyor;
- and wherein the first set of braking wheels and the second set of braking wheels are movable independently of each other along the shingling conveyor so as to take working positions at variable distances from an entrance end of the shingling conveyor;
- and wherein the braking wheels of the first set of braking wheels are carried by a first slide, and the braking wheels of the second set of braking wheels are carried by a second slide.
