Method and Apparatus for Applying an Elastic Material to a Moving Substrate in a Curved Path |
摘要 |
Aspects of the methods and apparatuses relate to making elastic laminates, and more particularly, methods and apparatuses for applying elastic material in a curved path onto an advancing substrate. The elastic material may be in various forms, such as for example, elastic strands and/or ribbons. Apparatuses and methods disclosed herein may also provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to the elastic material while being positioned on an advancing substrate. |

1. An apparatus for applying an elastic material along a curved path to a substrate, the apparatus comprising:
a slot die applicator including a slot opening, a first lip, and a second lip, the slot opening located between the first lip and the second lip; a substrate carrier comprising: a non-compliant support surface and a compliant pattern element, wherein the compliant pattern element includes a pattern surface, and wherein the compliant pattern element protrudes outward relative to the non-compliant support surface to define a first minimum distance, R1, between the pattern surface and the non-compliant support surface; wherein the substrate carrier is positioned adjacent the slot die applicator to define a nip between the pattern surface and the slot die applicator, and wherein the substrate carrier is adapted to advance a substrate in a machine direction through the nip; and a guide adapted to control a lateral position of an elastic member advancing into the nip between the pattern surface and the slot die applicator. |
