A band type strapping machine comprises a band feeding roller and a band returning roller wherein a first pressing roller is placed above the band feeding roller so as to be able to come in contact with the feeding roller, a second pressing roller is placed below the band returning roller so as to be able to come in contact with the returning roller and the band feeding roller and the band returing roller are driven in the same direction by a motor.

Band type strapping machine

A band type strapping machine comprises a swing lever, pivotally supporting a gripper for gripping a band, adapted to swing according to the rotation of a cam mounted on a cam shaft, a control bar engaged with the swing lever to follow the movement of the swing lever, a driving roller operating to engage with a band tightening roller, the driving roller being strongly brought into contact with the band tightening roller rotated at a low speed, high torque by actuation of a solenoid.

Band-returning and tightening apparatus for a band type strapping machine

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.
