  • Patent number: 10131090
    Abstract: A pasting roller has brush bristles planted in a surface thereof in straight lines or spirally to form a plurality of rows at predetermined intervals on the roller surface. An adhesive sheet S is pasted to work while moving the pasting roller and the work, which is the recipient, relative to and crossing each other. In this pasting process, a rotating speed of the pasting roller is adjusted according to a surface configuration of the work to render the pressure on the adhesive sheet constant.

  • Patent number: 9227812
    Abstract: While a transporting unit transports an adhesive sheet attached to a separator larger than the adhesive sheet, a chuck member on a tip of a swing arm of a separating unit holds a portion of the separator protruding from an end of the adhesive sheet. Under such a condition, the chuck member moves in a direction crossing a transportation direction of the adhesive sheet, and the transporting unit moves in the transportation direction in synchronization with the chuck member while folding back the separator at an end of a supporting plate contacting the separator as a starting point. Accordingly, the separator is separated from the adhesive sheet. The transporting unit transports while holding the adhesive sheet with the separator separated therefrom to join the adhesive sheet to a workpiece.
