FILM GUIDE DEVICE FOR A FILM BONDING APPARATUS

摘要

A film guide device for film bonding in which a movable guide roller support and guides the film and swing roller arms prevent the slackening of the film while the film is being fed. Also, a driving action of a rotation-drive source, which controls the movement of the movable guide roller support arms, is synchronized with the braking of the film supply role and the movement of the leading edge of the film towards the bonding surface. This device prevents longitudinal wrinkles in the film, misplacement on the bonding surface, and excessive tension on the film.
