A device for wrapping packets of cigarettes has a conveyor for feeding the packets successively along a path; and a number of heating heads, each of which is brought into contact with a respective packet and accompanies the packet from a contact station to a withdrawal station along part of the path; on reaching the withdrawal station, the heating heads are withdrawn, crosswise to the path, from the respective packets, and are conveyed, parallel to the path, from the withdrawal station to the contact station.
摘要:
Packets of cigarettes are conveyed from a packer to a cellophaner by a unit utilizing a first pocket conveyor connected to the infeed of the cellophaner, and a second pocket conveyor by which packets are directed onto the first conveyor at a transfer point; the unit is also equipped with a sensor that will check whether or not each pocket of the second conveyor is occupied by a packet, and a placement mechanism, interlocked to the sensor, of which the function is to fill any empty pockets of the first conveyor with packets recycled from the cellophaner.
