[0006] According to some embodiments of the present invention, the first base is provided with a first linear actuator for driving the first sliding seat, and the second base is provided with a second linear actuator for driving the second sliding seat. Thus, the adhesive laminating operation can be performed by controlling the first and second linear actuators through an electronic control program, facilitating automated production.

[0007] According to some embodiments of the present invention, an elastic sleeve is provided around the outer periphery of the roller, which can act as a buffer to prevent the cylindrical battery from being crushed during adhesive application.
