Abstract
This invention provides a separation method for an adhesive tape and a separation device that can reliably and efficiently perform the operation of removing the backing sheet from the adhesive sheet of the adhesive tape and can be automated with a simple structure. The adhesive tape comprises a base sheet, an adhesive sheet which is applied to the base sheet and a backing sheet laminated to the base sheet. According to the invention, one end of the adhesive tape is supported leaving that end as a free end. Separation means is used to bend the free end in the direction from a first surface of the adhesive tape to a second surface of the adhesive tape until slippage occurs between the adhesive sheet and backing sheet. While in this state, the separation means is withdrawn from the adhesive tape as it traces the end surface at the free end. Thus, the backing sheet is removed from the adhesive tape and can be affixed to an object.
