摘要

The light release film, the burble film being laminated by other side heavily on side of one side of the adhesion agent layer, being the film burble manner which burbles the light release film continually from the backing material less both sides pressure sensitive adhesive sheet which becomes, paralleling to the conveying turn roll of one or more which it applies to the backing material less both sides pressure sensitive adhesive sheet, while conveying direction of the light release film and/or changing the conveying direction of the backing material less both sides pressure sensitive adhesive sheet after the burbling, to burble the light release film from the part which contacts with the conveying turn roll of the backing material less both sides pressure sensitive adhesive sheet, at the same time, from the burble aspect of the light release film the backing material after the burbling lessThe occasion where the light release film is burbled from the backing material less₁ both sides pressure sensitive adhesive sheet angle to the burble aspect of the both sides pressure sensitive adhesive sheet ( ) with the film burble manner which is 28 degrees or more, stability the film burble manner which implements the suppression of burble and revolution arrival is offered.
