Target/
It is an object of the present invention to provide a laminating device that can perform laminating efficiently.

B. Structure of the Invention [Means for Solving Problems] The present invention provides a bonding object in which a bonded object is intermittently carried into a predetermined position of a bonding station with a pasting material, positioned and stopped, and then carried out again. The body carrier device is placed above the object to be bonded which has been carried to a predetermined position of the bonding station by the carrier device and is positioned and stopped. A mutual contact frictional resistance force is applied to the inner wall surface and/or other vertical contact members to prevent the entire stored stack from falling from the bottom opening in a natural state. Pressing the adhesive material storage case body or frame stably held by the above-mentioned case body or the upper surface of the adhesive material stack stored and held within the frame body to increase the frictional resistance holding force of the entire stacked body. A pasting material pressing device that sequentially presses and moves the pasting material downward inside the case body or frame body against the pressure, and a pasting material pressing device that presses and moves the pasting material downward in the case body or frame body one after another, and the pasting material that has been carried to a predetermined position of the pasting station by the carrier device and positioned and stopped, is pasted from above the carrier device. The gist of the bonding device is a bonding device comprising a lift device for moving objects to be bonded upwardly relative to the bottom opening of a material storage case body or a frame body, and lowering them back onto a carrier device.

[Effect]

a) The object to be laminated is carried by a carrier device to a laminating station with a pasting material, and is stopped at a predetermined position on the station.
