Abstract

1,255,619. Plywood; laminates. ROQUETTE FRERES. 24 Dec., 1968 [29 Dec., 1967], No. 61371/68. Headings B5L and B5N. [Also in Division C3] A process for the manufacture of laminates, e.g. plywood, comprises gluing together a plurality of plies with adhesive by an initial cold-pressing operation followed by a hotpressing operation, the adhesive used comprising a first ingredient which develops gluing power at an elevated temperature and a second ingredient which has gluing power at ordinary ambient temperatures and comprises starch which has been gelatinized, or pregelatinized, or modified and pregelatinized, or modified and liquefied. The adhesive may contain 2 to 50% by weight of the second ingredient. The first ingredient may be phenol-, urea-, resorcinol-, or melamineformaldehyde. The adhesive may also include a hardener for the adhesive, maize-starch, and wheat, rye, or nut flour. The starch may be obtained from maize, potato, wheat, manioc, sago, rice, or sweet potato by subjecting it to a preliminary treatment such as oxidation, dextrinizing, etherification or esterification. The second ingredient may be incorporated in the adhesive prior to, or at the time of, gluing.
