Patent ID: 6848239

Claim:
A band refeeding method in a banding packing machine in which, when the tip of the band to be supplied to a predetermined position of a band guide arch by the band supply means is stopped in such a state that it does not reach the predetermined position, band pull back means having a pair of rollers is driven in place of band supply means having a pair of rollers and a tip portion of a band is returned to an original band feeding position by the band pull back means, and then the band supply means is driven again, whereby the tip portion of the band is supplied to the predetermined position on the band guide arch side, comprising the steps of: previously detecting a correct length of the band to be pulled back to the original band feeding position by the band pull back means based on the number of rotations which is obtained from a start of the supply of the band by a touch roller constituting the band supply means to a stop thereof; and detecting the number of rotations of the touch roller corresponding to a smaller length than the amount of pulling back having the correct length detected previously, when the tip portion of the band is pulled back from such a position that it is stopped, reducing a rotating speed of the roller of the band pull back means when the number of rotations is detected, and subsequently rotating the roller of the band pull back means at the low speed, whereby the tip of the band is pulled back to a set position.
