摘要： A packer machine (1) and a wrapping method to produce a pack (2). The following are present: a wrapping line (7), which is provided with a plurality of movable wrapping devices (8); a first actuator (9), which is designed to cause the movable wrapping devices (8) to move; an insertion station (S1), which is arranged along the wrapping line (7) and where the wrapping line (7) receives one single wrapping material to be folded; an input station (S2), which is separate from the wrapping line (7) and has a loading opening (15); a transfer unit (12), which is designed to receive wrapping material groups in the input station (S2) and to direct the wrapping material towards the wrapping line (7); and at least one second actuator (13) which is independent of the first actuator (9) and is designed to move the transfer unit (12); a sensor device (16), which is designed to detect the presence of a body in the loading opening (15) of the input station (S2); and a control unit (20), which is configured to stop, when the packer machine (1) is working, the sole second actuator (13), thus allowing the first actuator (9) to normally operate, if the sensor device (16) detects the presence of a body in the loading opening (15) and to automatically restart the second actuator (13) if the sensor device (16) stops detecting the presence of a body in the loading opening (15).
