Method of transferring strip-like plastics bag material in packing machine |
摘要 |
This invention provides a method of transferring a strip-like plastic bag material in a packing machine. The method comprises the steps of transferring the bag material by a pair of intermittently operated pinching rollers. The bag material comprises a series of interconnected bags each having a heat-sealed bottom portion with a flap-like margin. The flap-like margin is raised during transfer of the bag material by guide means. The bottom portion is then detected by means of a microswitch having an elongated contact adapted to be releasably engaged with the flap-like margin as the flap-like margin is raised by the guide means during transfer of said bag material. The bag material is then stopped for a packing operation in response to detection by the microswitch of the bottom portion.
