Abstract
A unit for forming one or more layers of individual flat supports, taken from at least a first conveyor device, conveying the supports from upstream to downstream at a first speed, that includes a second conveyor device, conveying the supports from upstream to downstream at a second speed lower than the first speed, positioned downstream of the first conveyor device, equipped with a receiving zone for receiving the supports arriving from the first conveyor device, and having a curved portion, and means for forming the layer positioned above the second conveyor device, situated downstream of the curved portion, and driven at the second speed.
Claims10
A unit for forming one or more streams of individual flat substrates, arriving from at least one first conveyor device, conveying the substrates from upstream to downstream at a first speed, comprising:
- a second conveyor device, conveying the substrates from upstream to downstream at a second speed lower than the first speed, positioned downstream of the at least one first conveyor device, equipped with a receiving zone for the substrates arriving from the at least one first conveyor device, and having a curved portion,
- a device that forms the one or more streams, positioned above the second conveyor device, and driven at the second speed,
- wherein the device that forms the one or more streams is situated downstream of the curved portion, and
- the substrates leave the at least one first conveyor device downstream of an upstream end of the second conveyor device.
A unit for forming one or more streams of individual flat substrates, arriving from at least one first conveyor device, conveying the substrates from upstream to downstream at a first speed, comprising:
- a second conveyor device, conveying the substrates from upstream to downstream at a second speed lower than the first speed, positioned downstream of the at least one first conveyor device, equipped with a receiving zone for the substrates arriving from the at least one first conveyor device, and having a curved portion,
- a device that forms the one or more streams, positioned above the second conveyor device, and driven at the second speed,
- a first transfer device, positioned between the curved portion and the at least one first conveyor device and above the second conveyor device, and
- a second transfer device positioned substantially plumb with the curved portion and above the second conveyor device,
- wherein the device that forms the one or more streams is situated downstream of the curved portion, and
- the first and second transfer devices are rollers rotationally driven and rotating at a speed less than or substantially equal to that of the at least one first conveyor device, so as to drive and to slow the substrates.
