1. one kind for assembling the method for disposable pants type diaper (100), each pants-type diaper comprises base structure (102), described base structure has the first petiolarea (116) of being separated from each other and relative the second petiolarea (118) by center (119), and there is longitudinal axis (124) and lateral axes (126), described base structure (102) comprising:

  • top flat (138), egative film (136) and the absorbent cores (140) be arranged between described top flat (138) and described egative film (136), said method comprising the steps of;

    Advance the first continuous basal layer (162) with first surface and relative second surface longitudinal direction (MD) is upper, and at transverse direction (CD) upper limit fixed width degree;

    Advance the second continuous basal layer (164) with first surface and relative second surface described longitudinal direction (MD) is upper, and at described transverse direction (CD) upper limit fixed width degree;

    Described longitudinal direction (MD) advances elastic strands (168) with extended state;

    Between the first surface and the first surface of described second basal layer (164) of described first basal layer (162), the intermittently bonded described elastic strands (168) being in described extended state is to form elastic laminate material (402), described elastic laminate material (402) comprises along described longitudinal direction (MD) off and on isolated bond regions (405) and non-stick interface (403), wherein said elastic strands (168) is bonded to the first surface of described first basal layer (162) and the first surface of described second basal layer (164) in described bond regions (405), and wherein said elastic strands (168) is not bonded to the first surface of described first basal layer (162) and the first surface of described second basal layer (164) in described non-stick interface (403),Cut described elastic laminate material (402) to form the first continuous elastic laminated material (406) and the second continuous elastic laminated material (408) along described longitudinal direction (MD), described first continuous elastic laminated material (406) and described second continuous elastic laminated material (408) comprise bond regions (405) and non-stick interface (403) separately;

    At described transverse direction (CD) the described first continuous elastic laminated material (406) of upper separation and described second elastic laminate material (408);

    Elastic strands (168) is cut off in the non-stick interface (403) of described first continuous elastic laminated material (406) and described second elastic laminate material (408);

    AndDescribed first petiolarea (116) of each base structure that bonds (102) and the non-stick interface (403) of the first continuous elastic laminated material (406), and the non-stick interface (403) of described second petiolarea (118) of each base structure (102) that bonds and described second continuous elastic laminated material (408).
