摘要:
The present invention is intended to prevent cutting of resilient and elastic members by the welding process. the problem mentioned is solved by passing a first sheet layer (21), a second sheet layer (22) and resilient and elastic elongate members (19) continuously disposed in an md direction between the two sheet layers between a first roll (90) with convex junction portions (91) provided at circumferential intervals on an outer peripheral surface and a second roll (92) opposite the first roll (90), and pressurizing and heating the first sheet layer (21). ) and the second sheet layer (22) to form joined sheet sections (70) by welding the first sheet layer and the second sheet layer (22) such that they pass through the resilient and elastic members (19) and have md direction intervals therebetween, in which circumferentially continuous grooves (92d) are formed on a pressurizing surface of the second roll (92), resilient and elastic member passageways (19) are pressurized and heated at positions including second roll grooves (92d) and resilient and resilient member non-passage sections (19) are pressurized and heated at positions not including second roll grooves (92d) ).a presente invenção pretende evitar o corte dos membros resilientes e elásticos pelo processo de soldagem. o problema mencionado é solucionado pela passagem de uma primeira camada de folha (21), uma segunda camada de folha (22) e membros alongados, resilientes e elásticos (19), continuamente dispostos em uma direção md entre as duas camadas de folha, entre um primeiro rolo (90) com partes convexas de junção (91) fornecidas em intervalos circunferenciais em uma superfície periférica externa e um segundo rolo (92) oposto ao primeiro rolo (90), e a pressurização e aquecimento da primeira camada de folha (21) e da segunda camada de folha (22) para formar seções unidas de folha (70) pela soldagem da primeira camada de folha e da segunda camada de folha (22) de tal maneira a atravessarem os membros resilie
