This unit is used to rotate of 90° the product around a horizontal axis parallel to the direction of transport.
The pack unpender unit does not work with products in accumulation, as this would cause the line to block and it needs suitable free upstream and downstream space to guarantee the correct functioning in case of line stop.
The unit is composed by two paraller belt conveyors, one of which (hinged downstream) is lowered.
The pack falls for gravity it rests on the side on the lowest belt conveyor that takes it upwards to the starting level.
By placing the inclined belt conveyor in a horizontal position the unit becomes neutral (by-pass position).
The unit can upend the packs on the right or on the left, alternatively lowering the right or the left belt.
