ABSTRACT:
A system and process for fabricating pressboard from shredded paper coated with a thermoplastic material and a pair of facing webs includes placing the shredded poly-coated paper between the two traveling webs to form a composite, the composite then being passed in a manner to heat the thermoplastic material above its softening point to differentially repeatedly shift the traveling webs linearly relative to each other and to the shredded paper for enhanced bonding of the shreds to themselves and to the facing webs by passing them around a series of heated rollers defining a serpentine path, and then pressing the composite together while curing to bond the components, and cooling the product.
