The invention provides a manufacturing method of laminate sheet, which can eliminate the deficiency of setting area reduced by space restriction of device for feeding laminate sheet material and the difficulty of feeding to increase the production efficiency. In the laminate coiling unit (1), the tinsel and film shaped substrate are laminated, at the same time coiled into roller form, therefore the roller form layered product is formed. The roller form layered product stays at each rotation axis of spool-out device (2), cooperated with the linear speed of a double belt press machine (3), the roller form layered product is pulled out from the rotation axis. The pulled roller form layered product continuously inserts into the continuous belt of the double belt press machine, and then the roller form layered product is laminated to mould.
