  • Apparatus for making pressboard from poly-coated paper using relative movement of facing webs
    Patent number: 5380180
    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.

  • Process for making pressboard from poly-coated paper
    Patent number: 4810445
    Abstract: A method for continuously forming a pressboard product from shredded scrap paper having a thermoplastic coated thereon. The shredded paper is deposited between two continuous facing sheets. The sandwiched construction is heated using radiant or convection heat and then compressed to fuse the shredded paper together.

  • Apparatus and method for roll wrapping with poly-coated paper
    Patent number: 4716709
    Abstract: The specification discloses an apparatus and method for wrapping paper rolls with a paper coated with a thermoplastic material. The leading edge of the wrapper is adhered to the roll by softening the thermoplastic. After the wrapper is wrapped about the roll, the trailing edge of the wrapper is adhered to the wrapped roll by softening the thermoplastic. The wrapping apparatus includes a heatable transport bar for heating the desired portions of the wrapper and contacting the heated portions to the roll.
