APPARATUS FOR FORMING A PLURALITY OF FLEXIBLE POUCHES FROM A CONTINUOUS WEB OF FILM

摘要

An apparatus for forming a plurality of flexible pouches from a continuous web of film having a plurality of registration marks spaced a predetermined distance apart. The apparatus includes a film displacement mechanism, a registration mark sensor, and a controller. The film displacement mechanism includes at least one vertically oriented roller that rollingly engages with the continuous web of film. The film displacement mechanism adjusts the tension in the film by horizontally displacing the vertically oriented roller. The registration mark sensor is positioned upstream of the film displacement mechanism and is configured to detect the registration marks. The controller controls the film displacement mechanism to horizontally displace the film upon receipt of a signal from the registration mark sensor.
