COMPOSITE SHEET MANUFACTURING METHOD AND MANUFACTURING APPARATUS

A method for manufacturing a composite sheet has a step to introduce a first sheet (1) to an engaging part (33) of a first roller (31) and a second roller (32) having projections and depressions engaging with each other on the peripheral surfaces to deform the first sheet to have depressions and pro...

Zusammenfassung:	A method for manufacturing a composite sheet has a step to introduce a first sheet (1) to an engaging part (33) of a first roller (31) and a second roller (32) having projections and depressions engaging with each other on the peripheral surfaces to deform the first sheet to have depressions and projections while rotating the rollers; a step to conveys the deformed first sheet (1) having depressions and projections while holding the first sheet on the first roller (31), and overlaps the second sheet (2) with the first sheet (1) being conveyed; and a step to pinches the overlapped first and second sheets (1, 2) between projections (35) of the first roller (31) and an ultrasonic horn (42) of an ultrasonic bonding machine to apply ultrasonic vibrations to the sheets. In the method, fusion bonds (4) having through-holes (14) are formed during the application of the ultrasonic vibrations.
