METHOD AND SYSTEM FOR IMPROVING CREEP PERFORMANCE IN ELASTIC APPLICATIONS
20220250372 · 2022-08-11 ·

A method and system of using a polyolefin-based, hot melt adhesive improves creep performance of elastic strands adhered to another substrate. Some deflection, greater than 1°, of the exit angle formed by a line normal to the axis of a neutrally-positioned applicator and the elastic strand extending from the applicator is introduced. Preferably, deflection of the entrance angle is also introduced and a head tilt angle is also provided. The use of deflection improves creep performance or allows for a reduced amount of adhesive to be used to achieve the same or similar creep performance. The elastic strands may be used to form a leg cuff in personal care products, such as diapers, and the substrate to which they are applied could be a polyethylene film or non-woven materials.

A device for delivering a sealant material includes a first nozzle having a first nozzle head and a second nozzle having a second nozzle head. The first and second nozzle heads each independently have an outlet, an inlet opposite the outlet, and an open channel that extends through a body of the nozzle heads from the inlet to the outlet. The first nozzle is spaced apart from the second nozzle to form a space between the nozzle heads to allow a component to enter a first side of the device and exit a second side of the device while passing by the first and second nozzle heads. A notch is formed through the body of each of the first and second nozzle heads at a side where the component exits the device to distribute a sealant material onto each side of the component.
