Abstract:
A packaging device comprising a closed track (11) and constructed so that at least one part thereof can open and close,a truck (4) movably mounted on the track (11),a packaging material feeder (7) mounted on the truck and constructed to feed a packaging material (6) from a packaging material coil (5) rotatably mounted on the truck (4),a support (9) arranged to support an item for packaging (8) so that at least a part of said item for packaging (8) is arranged in the closed track (11), anda drive mechanism installed along the track (11) and being linked to the truck for driving the truck (4) along the track, said drive mechanism further including a motor mounted adjacent the track in a stationary position to move the drive mechanism and thereby the truck, wherein said packaging material coil (5) is connected through a torque limiter (24) to a drive generator (25) which applies a rotary force to the coil in a direction opposite to a direction in which the packaging material (6) is fed, so that, if the rotary force generated by drawing the packaging material (6) from the packaging material coil (5) decreases below a set value, the packaging material coil (5) can rotate in the opposite direction.
