Abstract
The present invention relates to a method and an apparatus for feeding and tightening a band wherein a touch roller is brought into compressive contact with a reverse rotation driving roller for a predetermined time when a signal for detecting a decrease in the speed of rotation including the stopping of a forward rotation touch roller is developed prior to the development of a signal for detecting the approach of the front end of the fed band to a mechanism for grasping the band front end; whereby the band is restored and the compressive contact of the reverse rotation touch roller is released after passage of the predetermined time so as to restore the band; the band is then restored by means of a tension roller which is rotated at a lower speed and driven at a higher torque as compared with the reverse rotation roller and a touch roller which is brought into compressive contact with and capable of separating from the tension roller; and the band is finally tightened by starting the reverse rotation of the tension after the reverse rotation touch roller is brought into slidable contact with the reverse rotation driving roller through the intermediary of the band and is rotated in subordination thereto and then by bringing the touch roller into compressive contact with the tension roller by means of the development of a signal for detecting a decrease in the speed of rotation including the stoppage of the reverse rotation touch roller.
