Definitions

  • the upper substrate and the lower substrate are combined on the upper surface and the lower surface of the elastic film to form a sheet, and then fixed by an ultrasonic device, so that the upper substrate, the elastic film, and the lower substrate are connected to form a fastening point.
  • Each fastening point is distributed to form a plurality of partition lines, and each partition line is arranged at intervals along the transverse direction;
  • vent holes are formed at the upper cutting part, the lower cutting part, the left cutting part and the right cutting part, and the width of each vent hole in the transverse direction is Greater than the length in the vertical direction, forming a flat shape.
  • Fig. 3 is a display state diagram of Fig. 1;
  • Fig. 5 is a schematic structural view of the manufacturing device of the elastic sheet of the present invention.
  • the above-mentioned mechanisms are conventional mechanisms in the field, and the specific structures have been disclosed, and the relevant patents of the applicant can be referred to.
  • the ultrasonic device 95 and the cutting device 97 need to have a specific arrangement of points.
  • the cutting device 97 can adopt an ultrasonic mechanism. When using an ultrasonic mechanism, it can form a plurality of cutting units on the sheet at one time. As shown in FIG. 3 , the cutting area between two adjacent dividing lines Multiple cutting units form the most basic welding unit.

Abstract

Feuille élastique et procédé de fabrication associé, comprenant un substrat supérieur (1), un substrat inférieur (2) et un film élastique (3). Le substrat supérieur (1) et le substrat inférieur (2) sont des feuilles perméables à l'air ; des points de fixation (4) sont formés de manière fixe entre le substrat supérieur (1), le film élastique (3) et le substrat inférieur (2) ; les points de fixation (4) sont répartis pour former une pluralité de lignes de séparation (F) ; les lignes de séparation (F) sont agencées à intervalles dans une direction transversale ; au moins une unité de coupe (6) est agencée entre deux lignes de séparation adjacentes (F) ; chaque unité de coupe (6) comprend une partie de coupe supérieure allongée (61) agencée pour une coupe verticale, une partie de coupe inférieure allongée (62) agencée pour une coupe verticale, une partie de coupe gauche (63) située sur le côté gauche de la partie de coupe supérieure (61) pour une coupe verticale, et une partie de coupe droite (64) située sur le côté droit de la partie de coupe inférieure (62) pour une coupe verticale. La perméabilité à l'air d'une feuille élastique peut être améliorée et un bon confort est assuré.
