WIPO Patent Application WO/2018/116996
Kind Code:
A1
Abstract:
A composite sheet manufacturing method is provided with: a step of introducing a first sheet (1) into a meshing part (33) and deforming the first sheet (1) into a concavo-convex shape while rotating a first roll (31) and a second roll (32) having meshing concavities and convexities on peripheral surface parts thereof; a step of conveying the first sheet (1), deformed into the concavo-convex shape, while carrying the same on the first roll (31), and overlapping a second sheet (2) with the first sheet (1) being conveyed; and a step of sandwiching the overlapped sheets (1 and 2) between a convex part (35) of the first roll (31) and an ultrasonic horn (42) of a ultrasonic welding machine, and applying ultrasonic vibrations. During the application of the ultrasonic vibrations in the ultrasonic treatment step, a welded part (4) having a through-hole (14) is formed.
