MEMBRANE STRAPPING APPARATUS

摘要

A membrance strapping apparatus includes a hold-pull rod pivotally connected with a membrance release unit and a roller unit. A pulling-force adjusting unit is provided between the hold-pull rod and the roller unit and the membrance release unit is provided with a shaft rod for supporting a membrance roll. Thus, a user can conveniently make use of the membrance strapping apparatus to release membrance for carrying out strapping operation. The pulling-force adjusting unit can be operated for controlling pivotal rotation angles of the roller unit to enable a user to adjust directions and tightness of strapping in accordance with practical need and assist the user to conveniently complete strapping work for firmly strapping an article.
