The operation of the above-mentioned laminate manufacturing apparatus EA will be described.
First, with respect to the laminated body manufacturing apparatus EA in which each member is arranged at the initial position shown by the solid line in FIG. 1 (A), the user of the laminated body manufacturing apparatus EA (hereinafter, simply referred to as “user”) is shown. Do not input the signal to start automatic operation via an operation means such as an operation panel or a personal computer. Next, as shown in FIG. 1A, a user or a transport means (not shown) such as an articulated robot or a belt conveyor abuts the base sheet BS on which the adhesive sheet base material ASB is laminated on the holding surface 12A. Then, the sticking means 10 drives a depressurizing means (not shown) to start adsorbing and holding the base sheet BS on the holding surface 12A.

Remove the BS. At this time, the unnecessary sheet portion US is removed together with the base sheet BS, and a laminated body LM in which the adhesive sheet AS is attached to the adherend WK is formed. Then, the removing means 30 drives the articulated robot 31 to administer the base sheet BS to which the unnecessary sheet portion US is attached into a waste box (not shown), and then returns the suction pad 32 to the initial position. Next, after the deforming means 20 drives the linear motion motor 27A and the chuck cylinder 27C to return the support table 28 and the gripping member 27D to the initial positions, the user or the transporting means (not shown) transports the integrated product UP to the next step. Then, the same operation as described above is repeated thereafter.
