Claims

[Claims for Utility Model Registration] 1. First, second, and third portions provided parallel to each other.
The pulleys are fitted loosely on the transmission shaft, and each pulley can be driven and rotated simultaneously by a single power via a belt, and the control operation device selectively operates the pulleys to separate and disengage between each pulley and the transmission shaft. A clutch is interposed, and the third transmission shaft applies pressure to a gripping roller for feeding the strap and operates a device for pressing, welding, and cutting the strap according to a predetermined timing and sequence via a speed reducer. The first and second transmission shafts are fitted with two sets of gear trains that mesh with each other, allowing one specific gear to rotate in the forward and reverse directions, and the specific gear to rotate in the belt. A power transmission mechanism A for feeding the string, which is integrated with a friction roll for feeding the string, and is configured to transmit power by meshing with a friction gear whose transmission friction force is adjustable;
' One end of the holding seat is pivotally supported on the machine frame, and a gripping roll B is attached to the machine frame to press the webbing against the string feeding friction roll. By rotating a cam roller that rotates in response to transmission from the shaft, a load can be applied to the holding seat of the gripping roll in a manner that can be selected to be strong or weak. Coil springs with different biasing forces, which can be finely adjusted by separate screws, and of different lengths are fitted concentrically, and the springs are connected to the free end of the holding seat of the gripping roller through a stopper. A strap feeding device for a packaging machine, characterized in that it consists of three parts, including a pressure regulating device C brought into contact with each other. 2. A billing device characterized in that the transmission frictional force of the friction gear in the power transmission device is smaller than the transmission frictional force that causes the gripping roll to send the strap along with the feeding friction roll due to the load from the pressure adjustment device. 3. The first, second, and third power transmission shafts are provided with a corresponding number of power transmission devices, gripping rolls, and pressure adjustment devices. The strap feeding device described in item 1 or 2.
