    摘要: The invention relates to a method for peeling a pressure-sensitive adhesive tape including: a pressure-sensitive adhesive layer. The pressure-sensitive adhesive tape has a thickness greater than 150 μm and smaller than 1,500 μm, an elongation at break of 600% to 3,000%, and a stress at break of 2.5 to 80.0 MPa. According to the invention, the conformity and the adhesion with respect to an adherend, particularly, a hard adherend, are excellent, and excellent re-peeling properties are obtained, so that the pressure-sensitive adhesive tape can be stretched and peeled off in a horizontal direction, without necessity for embrittling the pressure-sensitive adhesive tape by heating or by using an organic solvent or the like or without remaining of the pressure-sensitive adhesive on the adherend, in a case of peeling the pressure-sensitive adhesive tape.

    摘要: A film-removing apparatus configured to remove a protecting film from a workpiece includes a supporting module configured to support the workpiece, a clamping module configured to clamp the workpiece supported by the supporting module, and a peeling module. The peeling module includes a first peeling member and a second peeling member. The first peeling member includes a bearing surface. The peeling module moves towards the clamping module to bring the bearing surface to below the protecting film, the second peeling member moves towards the protecting film to cooperate with the first peeling member in clamping the protecting member. The peeling module is then moved away from the clamping module to peel off the protecting film.

    摘要: A pad removal device includes a pad guide extending along a first direction. The pad guide includes a first affixing component configured to affix a first end of the pad guide to a pad at a first pad edge location, and a second affixing component configured to affix a second end of the pad guide to the pad at a second pad edge location opposite the first pad edge location. The pad removal device further includes an actuator attached to the pad guide, and a control assembly coupled to the actuator and configured to cause the actuator to move the first end toward the second end along the first direction. The pad guide is configured to extend in a second direction different from the first direction by an amount dependent on a distance between the first end and the second end.
