  • Patent number: 4314871
    Abstract: The invention relates to a method of and apparatus for laminating timber to form beams for use in structural and other uses. The beam is formed from timber strips forced through a set of pressure means comprising preferably pressure rollers in a side by side relationship with bonding medium applied to the vertical sides of the strips. These sides preferably have interengaging castellations formed thereon for improved connection between the strips. The strips are formed from timber lengths which are connected together preferably by finger jointing. The bonding medium is applied to the side faces of the timber lengths and to the ends at the same time. A braking system ensures that the ends of timber lengths are spaced well apart to enable adequate bonding medium to be applied to the timber length ends.
