Abstract: A coating-film transfer tool is configured to positively absorb rotation of a head part caused when pressed and an effect of lean of the head part, and such a configuration contributes to favorable and uniform transfer. A member 4 is disposed at one end of a support column 2 supporting a head part 1 at the other end. A distance between the axial center of the support column 2 and its periphery varies depending on a position in the rotation direction. Sandwiching plates 3 resiliently sandwich the facing sides of the member 4 with the narrowest gap, when the head part 1 is not pressing a transfer target. When the head part 1 rotates around the axis of the support column 2 in a state pressing the transfer target, the member 4 rotates to forcibly and significantly widen the gap between the sandwiching plates and generate a restoring force.

Abstract: An apparatus for automatically peeling a removal tape from a removal-tape-attached adhesive tape and affixing the adhesive tape to a battery module. A removal-tape-attached adhesive insulation tape supplied from an uncoiler is held in a folded state by means of a carrier plate. The carrier plate reciprocates between a first position and a second position. When the carrier plate has moved from the first position to the second position, a tape holding unit holds the tape by means of suction. Subsequently, as a result of movement of the carrier plate from the second position to the first position, the removal tape is peeled from the removal-tape-attached adhesive insulation tape T, thereby uncovering an adhesive surface of the adhesive tape. The battery module is dropped toward the adhesive tape at an inclination with reference to the vertical direction, whereby the adhesive tape is affixed to the battery module.
