Abstract:
1. A foam cushion pad formation assembly, comprising: a conveyance assembly having at least one moving conveyor component in the form of an endless belt presenting a pad shape formation surface, which pad shape formation surface is a convoluted surface arranged to shape pads of a pad chain received by said conveyance assembly, said pads comprising enclosed foam material; and a separation device which is positioned downstream of a conveyance assembly entrance as to separate shaped pads of the pad chain received by said conveyance assembly, wherein said moving conveyor component comprises a base with projections that extend off said base, said projections being formed monolithically with said base; said convoluted surface extends over the full length of said pad shape formation surface and comprises a number of projections and recesses formed in a continuous sinusoidal pattern wherein: the projections have a peak height of from 0.3 to 2.0 in., the recesses have a lower trough height of from 0.1 to 0.7 in., and adjacent projections along a common horizontal axis are spaced at a peak-to-peak wavelength of from 0.5 to 5 in.; and said moving conveyor component is constructed of a material that, with the sinusoidal pattern of projections and recesses, renders the moving conveyor component conformable with an arc of a return loop in a conveyance path of said moving conveyor component.
