Abstract
A method of utilizing a scrim of elastic material including cutting the elastic strands within a disposable undergarment is disclosed. The method generally follows the steps of providing two webs of fabric and an elastic scrim of mesh-like design, adhering the scrim between the two webs of fabric, determining areas where elastic material is not required, compressing the non-elastic areas with a thermal compression tool, and forming a disposable undergarment.
Claims12
A method of cutting elastic strands between layers of carrier webs comprising;
- providing a first layer of carrier web material;
- providing a second layer of carrier web material;
- applying adhesive to at least one of said layers of carrier material across a first area;
- providing at least one elastic scrim area in a second area, the second area including the first area, and having a machine direction dimension and a cross-machine direction dimension, the scrim having a predetermined tension and applying the elastic scrim to the one of said layers of carrier web material with adhesive applied thereto;
- compressing the first and second layers together such that the scrim is secured between the layers;
- and
- severing the elastic scrim in portions of second area but not in the first area, by passing the web through a severing device comprising a heat compression tool and an anvil and compressing the web in the second area, thereby allowing the elastic scrim to deactivate in the second area but not the first area.

A method of cutting elastic strands between layers of carrier webs comprising:
- providing a first layer of carrier web material;
- providing a second layer of carrier web material;
- applying adhesive to at least one of said layers of carrier material to a first area where stretch is desired, and not applying adhesive to a second area, the second area defining where stretch is not desired;
- providing two sections of elastic scrim across both the first area and the second area, the elastic scrim having a predetermined tension;
- applying each of said sections of elastic scrim to a predetermined location on the one of said layers of carrier web material with adhesive applied thereto;
- compressing the first and second layers together such that the scrim is secured between the layers thereby creating a composite having two scrim areas;
- folding said composite to place said two scrim areas into proximity with one another;
- and
- severing the elastic scrim sections in the second area by passing the web through a severing device comprising a heat compression tool and an anvil and compressing the composite in the second area, thereby severing the elastic scrim sections in both the machine direction dimension and the cross-machine direction dimension across the second area, leaving the elastic scrim of the second area deactivated.

A method of cutting elastic strands between layers of carrier webs comprising:
- providing a first layer of carrier web material;
- providing a second layer of carrier web material;
- applying intermittent adhesive to one of said layers of carrier material thereby defining an elasticized zone where adhesive has been applied and a non-elasticized zone where adhesive has not been applied;
- providing a large elastic scrim across the elasticized zone and the non-elasticized zone with a predetermined tension and applying the elastic scrim to the one of said layers of carrier web material with adhesive applied thereto;
- compressing the first and second layers together such that the scrim is secured between the layers;
- and
- severing the elastic scrim area across the non-elasticized zone by passing the web through a severing device comprising a heat compression tool and an anvil and compressing the web across the elasticized zone and the non-elasticized zone thereby leaving the elastic scrim of the non- elasticized zone not adherent to the first or second layers of carrier web material, where elastic material is not desired.
