  • This invention relates to the joining or uniting of pieces or plies and especially where a wood surface is concerned, and more particularly with employment of heat. It is among the objects of the invention to pro vide an improved method of simplified and direct joining or uniting, making possible a continuous type of operation where desired. 7

  • the formation of the bond is accomplished by setting the adhesive by heat and with pressure; however the heat is applied in a manner not complicating the pressing procedure.
  • the adhesive base may be applied to at least one of the surfaces to be joined, and such heat as is to be employed is stored or provided before the pressing, by initially heating at least one of the pieces concerned.
