Abstract

Foam is used to acoustically insulate machine covers, such as the rectangular cover C illustrated in FIG. 1. A 3-D template T has an exterior configuration that generally corresponds to portions of the interior of the cover, and together they define cavities into which the foam may be applied, such as by spraying. The template is then removed, leaving the foam in place against the interior surface of the cover.

Three Dimensional Template for the Application of Spray Foam

Foam is used to acoustically insulate machine covers, such as the rectangular cover C illustrated in FIG. 1. A 3-D template T has an exterior configuration that generally corresponds to portions of the interior of the cover, and together they define cavities into which the foam may be applied, such as by spraying. The template is then removed, leaving the foam in place against the interior surface of the cover.

The template includes exterior side surfaces 1 - 9 and bottom surface 10, which are in face-to-face mating contact with the interior side surfaces 20 - 23 and bottom surface 24 of the machine cover C. Dot-dash lines illustrate how the template is nested into the cover. With the template in position inside the cover, cavities are defined for injection of the foam. Specifically, referring to FIG. 2, foam insert 30 has its exte surfaces 31, 32 formed by the interior cover surfaces 20, 21 and the interior surfaces 33, 34 formed by the exterior template surfaces 1, 2. The end surfaces 35, 36 of the foam insert are formed, respectively, by the exterior surface 3 of the template and interior surface 23 of the machine cover. The surfaces of foam inserts 40, 41 are formed in a similar manner.

The configuration of the template may be changed as necessary or desirable to change the shape of the foam inserts
