Abstract
A wrapper machine has a coiling station for forming a coil of a flexible article with an elongated shape, a packaging station for wrapping a stretch film around the coil, and a transfer unit for transferring the coil from the coiling station to a packaging station, where the coil is wrapped in a stretch film and moved intermittently around a rotation axis by two holding jaws mounted to rotate due to the thrust of respective crank mechanisms connected with an electric motor via an interposed transmission shaft.
Claims11
A wrapper machine for packaging flexible articles with an elongated shape, the wrapper machine comprising:
- a coiling station for forming a coil of a flexible article with an elongated shape;
- a packaging station for wrapping a stretch film around the coil;
- and
- a transfer unit for transferring the coil from the coiling station to the packaging station in a feeding direction that is transverse to a longitudinal axis of the coil;
- wherein the packaging station comprises, in turn, a wrapper assembly mounted to continuously rotate around a first rotation axis that is parallel to the feeding direction and wrap the stretch film around the coil, and a rotary clamp that is configured to rotate the coil around a second rotation axis transverse to the first rotation axis and that is provided with a pair of holding jaws and with an operating device for moving the holding jaws around the second rotation axis, and
- wherein the operating device comprises an electric motor, a transmission shaft mounted to rotate, due to a thrust of the electric motor, around a third rotation axis parallel to the second rotation axis and, for each holding jaw, a respective crank mechanism for connecting the transmission shaft and the holding jaw to one another.
