Claims

[Scope of Claim for Utility Model Registration] (1) Right and left parts that are raised and lowered by a cam on the cam shaft and form a mechanism for gripping the band tip side, gripping the band supply side, and welding the band overlapping part with the slide table. , a packing machine equipped with a mechanism that supplies the band to the outside of the main body by forward rotation of a feed roller via a band shooter onto each press member consisting of a medium press, and then pulls the band back into the main body by reversing the feed roller after gripping the front end of the band. In this case, a guide plate is provided to cover the band open edges of the left and right bandways each having a U-shaped cross section and having a band passage groove with one side open, and the open edge of the left bandway is placed against the guide plate. A cam on the cam shaft is provided in the vicinity of the opening end of the left bandway so as to be able to come into contact with and separate from the left bandway freely via a hinge, and an interlocking rod is provided at the edge in the width direction of the right bandway, is fitted into a guide body attached to the machine frame of the welding mechanism so as to be movable forward and backward, and the right bandway is provided so as to be opened in conjunction with the sliding movement of the left bandway via the interlocking rod. Bandway opening device for packing machines. (2) A shaft provided at one end of the interlocking rod is passed through an elongated hole drilled in a support plate for sliding the left bandway, so that the right bandway can freely move forward and backward as the left bandway slides. 2. A bandway opening device for a packaging machine according to claim 1, wherein the bandway opening device is provided to be interlocked with each other.
