Abstract: The production, by either a batch process or a continuous process, of vehicle seat trim pads or like articles of cured polymer no-gel latex foam and having convex or crowned surfaces free of congealed polymer skin, is disclosed. In the process, a backing fabric is first laid on a pervious supporting surface. A no-gel latex foam is then deposited on the fabric, and an open-bottom open-top grid of a height not greater than that of the deposited mass of latex foam is placed into the latter, excess latex foam above the top plane of the grid being scraped off to impart to each pocket or island of foam a smooth and level top surface. The entire assembly is then subjected to dry heat to effect both a rapid dehydration and a curing of the latex foam. During the initial stage of this operation, the no-gel latex foam expands somewhat so that the top surface of each island thereof becomes crowned without having to be disposed in contact with a mold surface of appropriate contours.

Abstract: A no-gel latex foam is formed by curing a no-gel latex foam froth on a water vapor permeable foraminous support that has been coated with a flock. During curing, the foam froth dehydrates through an upper free surface and at its lower supported surface through the flock and the foraminous supporting means. When the cured foam is removed from the foraminous supporting means, a portion of the flock adheres to the foam undersurface and another portion of the flock is left as a residue.

Abstract: A no-gel latex foam is formed by curing a no-gel latex foam froth on a water vapor-permeable foraminous support means comprising a backing material that has been coated with a water soluble release agent. During curing, the foam froth dehydrates through an upper free surface and at its lower supported surface through the release agent and the foraminous support means. The cured foam is then removed from the foraminous support means free of any backing material.
