Abstract: A film is delivered from a delivery roller and another film is delivered from another delivery roller. The two films are introduced between a heater and a receiver. The heater presses the two films against the receiver to bond the films. Then, the rear end of the film is cut off with fusing and the front end of another film is cut off with fusing by wire heaters. The bonded film is transferred through drive and pinch rolls to an accumulator for storing the film and is spread to open slits by holding rolls to form a longitudinal web, which is laminated on a lateral web manufactured in another process to form a reticulate non-woven fabric.
