ABSTRACT:
A band type strapping machine comprises a feeding and tightening roller driven by a motor, an auxiliary roller in contact with the feeding and tightening roller, a cam shaft which is rotated by the motor through a reduction gear and a clutch mechanism and which has cams for respectively actuating a rear gripper, a heater, a press bar and a front gripper, wherein the motor is capable of instantaneous change of normal and reverse rotations and has a large starting torque, and an electromagnetic clutch is fitted to the rotary shaft of the tightening and feeding roller so as to be movable in the axial direction depending upon increase of a band tightening force whereby detection of the tightening force caused by the movement of the electromagnetic clutch is mechanically related to the engagement or disengagement of the clutch mechanism.
