ABSTRACT:
The present invention relates to a method and apparatus for segmenting groove molded building boards. In a preferred embodiment, a sheet of groove molded board is conveyed onto a first apparatus which separates the side edge trim scrap from the board. The board then passes onto a segmenting apparatus comprising a first horizontal conveyor, an inclined conveyor, a second generally horizontal conveyor, and adjustably mounted roller assemblies. The first apparatus removes the side-edge trim scrap from the board and the second segmenting apparatus breaks the groove molded board transversely along the groove molded lines. In addition, the second apparatus separates the leading and trailing edge scrap so as to provide individual board panels which require no additional trimming. As an alternative, two segmenting conveyors can be used in tandem so as to remove all of the scrap, thereby obviating the need for the first trim-scrap removing apparatus.
