The operation of the sheet sticking apparatus EA1 employing the temperature changing device EA as the cutting means will be described.
First, a user of the sheet sticking device EA1 (hereinafter simply referred to as "user") moves the sheet sticking device EA1 in which each member is arranged at the initial position indicated by the solid line in FIG. After the raw fabric RS is set in the machine, a signal for starting automatic operation is inputted via an operation means (not shown) such as an operation panel or a personal computer. Then, the temperature changing means 20 drives the coil heater 21 to heat the cutting blade CM4 by heating the blade holding member CM3. Heat to and hold temperature. Further, when the sheet pasting means 30 drives the rotating motor 35A to feed the original sheet RS, and the leading edge of the leading adhesive sheet base material AB in the feeding direction is peeled off by the peeling edge 33A of the peeling plate 33 for a predetermined length, The driving of the rotation motor 35A is stopped.

Next, when a user or a conveying means (not shown) such as an articulated robot or a belt conveyor places the adherend WK on the inner support surface 38A as shown in FIG. The depressurizing means is driven to start sucking and holding the adherend WK on the inner supporting surface 38A. Thereafter, the sheet pasting means 30 drives the linear motor 37 to move the support table 38 to the left, and when the support table 38 reaches a predetermined position, the rotation motor 35A is driven to move the support table 38 The raw fabric RS is delivered according to the speed. As a result, the adhesive sheet base AB is separated from the release sheet RL, and the adhesive sheet base AB separated from the release sheet RL is pressed by the pressure roller 34 as indicated by the two-dot chain line in FIG. 1(A).
