PAD FORMATION METHOD, ASSEMBLY AND PAD PRODUCED THEREBY

摘要

A foam cushion pad formation assembly that includes a conveyance assembly having at least one moving conveyor component presenting a pad shape formation surface, which surface is convoluted and arranged to shape sealed enclosures of a pad chain received by the conveyance assembly. A separation device is provided to separate shaped pads of the pad chain received by said conveyor device. The shaped pads include convoluted surface that are formed by way of gripping projection and recesses combinations in the moving conveyor component. Embodiments include sensing for non separated pads from a downstream end of the bag chain, pad chain separation enhancement devices, and various control system including the requirement of confirmation of separation before feeding a new pad enclosure as in one containing liquid polyurethane precursor chemicals. An embodiment includes a pad chain path disruption sensor and a form feed control which implements the formation of pad enclosures free of filler material in a bridging region between the outlet end of the enclosure formation means and the conveyance assembly.
