Apparatus and method for manufacturing laminate

A method for manufacturing a layered material including an elastic thread sandwiched between a pair of sheets, the method using a device for manufacturing the layered material, the device comprising:

• a pair of nip rolls arranged with their axes parallel to each other for nipping the elastic thread between the pair of sheets being conveyed in a conveyance direction;
• a needle arranged upstream of the nip rolls in the conveyance direction for guiding and arranging the elastic thread between the pair of sheets while dispensing the elastic thread through a through hole, through which the elastic thread passes;
• a needle body that holds the needle;
• a reciprocating section, to which the needle body is attached, for reciprocating in a width direction, which intersects with the conveyance direction;
• and
• a stabilizer that stabilizes the reciprocation of the reciprocating section, the method comprising:
• a step of continuously supplying the pair of sheets to a nipping section between the pair of nip rolls;
• a step of continuously dispensing and supplying the elastic thread through the through hole of the needle between the pair of sheets immediately before the pair of sheets are supplied to the nipping section between the pair of nip rolls;
• a step of reciprocating the reciprocating section in the width direction to reciprocate a position of the needle in the width direction, thereby arranging the elastic thread in a wave-like form between the pair of sheets;
• and
• a step in which the stabilizer guides the reciprocating section in a non-contact manner by blowing out air or by magnetic force while reciprocating the needle.
