Method for attachment of elastic members around leg-holes of disposable garments

Claim 1

A method for attachment of elastic members around leg-holes of a disposable garment, the method comprising steps of: a) forming a base web by continuosly feeding and bonding with adhesive first and second continuous elastic members, while keeping them stretched, onto a top surface of a first web, which is being moved, so that the elastic members describe undulating curves with summits as well as troughs of the respective curves being symmetrically opposed to each other and cross each other at their ends so as to form annular elastic areas; b) forming a first composite web by severing the base web along respective lines transversely extending through crossings at which the first and second continuous elastic members cross each other and intermittently bonding respective severed strips with adhesive onto a second web, which is being moved, along its longitudinally extending central area; c) forming a second composite web by bonding a third web, which is being moved, with adhesive onto a top surface of the first composite web; d) forming continuous garments by cutting off portions of the second composite web surrounded by the respective annular elastic areas to form notches for the leg-holes; and e) obtaining individual garments by severing the continuous garments along lines each dividing the associated one of the annular elastic areas in two longitudinally of the second composite web.

Claim 2

A method for attachment of elastic members around leg-holes of a disposable garment, the method comprising steps of: a) forming a base web by continuosly feeding and bonding with adhesive first and second continuous elastic members, while keeping them stretched, onto a top surface of a first web, which is being moved, so that the elastic members describe undulating curves with summits as well as troughs of the respective curves being symmetrically opposed to each other and cross each other at their ends so as to form annular elastic areas; b) forming a first composite web by severing the base web along respective lines transversely extending through crossings at which the first and second continuous elastic members cross each other and intermittently bonding respective severed strips with adhesive onto a second web, which is being moved, along its longitudinally extending central area; c) forming a second composite web by bonding a third web, which is being moved, with adhesive onto a top surface of the first composite web; d) forming continuous garments by cutting off portions of the second composite web surrounded by the respective annular elastic areas to form notches for the leg-holes; and e) obtaining individual garments by severing the continuous garments along lines each dividing the associated one of the annular elastic areas in two longitudinally of the second composite web.

Claim 3

A method for attachment of elastic members around leg-holes of disposable garment, the method comprising steps of: a) forming a base web by continuously feeding and bonding with adhesive first and second continuous elastic members, while keeping them stretched, onto a top surface of a first web, which is being moved, so that the elastic members describe undulating curves with summits as well as troughs of the respective curves being symmetrically opposed to each other and cross each other at their ends so as to form annular elastic areas; b) forming a first composite web by severing the base web along respective lines transversely extending through crossings at which the first and second continuous elastic members cross each other and intermittently bonding respective severed strips with adhesive onto a second web, which is being moved, along its longitudinally extending central area; c) forming a second composite web by bonding a third web, which is being moved, with adhesive onto a top surface of the first composite web; d) folding the second composite web along its longitudinally extending center line which divides the second composite web in two transversely thereof; e) forming notches for respective leg-holes by cutting off portions of the second composite web surrounded by the respective annular elastic areas before or after said step (d); f) forming continuous garments by providing the second composite web with seal lines along lines dividing the respective annular elastic areas in two and thereby defining the individual garments; and g) severing off the individual garments from the continuous garments, simultaneously with or after said step (f), so as to leave the seal lines and thereby to define side edges of the respective individual garments.

Claim 4

A method for attachment of elastic members around leg-holes of disposable garment, the method comprising steps of: a) forming a base web by continuously feeding and bonding with adhesive first and second continuous elastic members, while keeping them stretched, onto a top surface of a first web, which is being moved, so that the elastic members describe undulating curves with summits as well as troughs of the respective curves being symmetrically opposed to each other and cross each other at their ends so as to form annular elastic areas; b) forming a first composite web by severing the base web along respective lines transversely extending through crossings at which the first and second continuous elastic members cross each other and intermittently bonding respective severed strips with adhesive onto a second web, which is being moved, along its longitudinally extending central area; c) forming a second composite web by bonding a third web, which is being moved, with adhesive onto a top surface of the first composite web; d) folding the second composite web along its longitudinally extending center line which divides the second composite web in two transversely thereof; e) forming notches for respective leg-holes by cutting off portions of the second composite web surrounded by the respective annular elastic areas before or after said step (d); f) forming continuous garments by providing the second composite web with seal lines along lines dividing the respective annular elastic areas in two and thereby defining the individual garments; and g) severing off the individual garments from the continuous garments, simultaneously with or after said step (f), so as to leave the seal lines and thereby to define side edges of the respective individual garments.
