BAND GUIDING ARCH FOR STRAPPING MACHINE

摘要

The arch guide for a strapping machine comprises corner sections interconnected by linear sectios. Each of those sections includes inner and outer peripheral portions disposed, respectivley, closer to and farther from a centre of the guide. The inner and outer portions form a guide passage for the band, the passage being open at a side facing a guide plate. The open side of the arch guide is yieldably urged against the guide plate to close the open side. The inner portion extends toward the guide plate at an inwardly directed inclination to facilitate movement of the arch guide away from the guide plate when the band is being withdrawn from the passage. A guide extends from the leading end of a linear section into a trailing end of a corner section for directing an advancing band toward the outer portion of the corner section.
