BAND REFEEDING METHOD IN BANDING PACKING MACHINE AND BANDINGPACKING MACHINE HAVING REFEEDING MECHANISM

摘要

It is an object to provide a band refeeding method in a banding packing machine which can prevent the tip portion of a band from being excessively pulled back even if the band is not supplied correctly but is automatically pulled back, and can stay the band in a predetermined position and can successively supply the band to the band guide arch side. A length of a band to be pulled back to an original position by band pull back means (84) is previously detected based on the number of rotations of a touch roller (88) constituting band supply means (82). In addition, the number of rotations of the touch roller (88) before reaching a predetected set value is detected when the tip portion of the band is pulled back. Then, a rotating speed of a roller (94) of the band pull back means (84) is reduced when the number of rotations is detected. Therefore, the roller (94) of the band pull back means (84) is subsequently rotated at the low speed, thereby pulling back the tip of the band to a predetermined position.
