  • Patent number: 5613417
    Abstract: In order to enhance the effectiveness and efficiency of forming a groove in a board, an apparatus and method are disclosed. The apparatus includes a station for feeding the board from a supply of boards, a table for supporting the board upon receipt from the feeding station, a cutter for forming the groove while the board is supported by the table, and a station for removing the board after the groove has been formed. It is among the unique aspects of the disclosure that the table is moved relative to the cutter such that a grooved board can be removed from the table with the material defining the groove having been separated therefrom just after another board on the table has been grooved. The method includes the steps of feeding the board from a supply of boards at a feeding station, supporting the board after the board has been fed from the feeding station, forming the groove in the board while the board is being supported, and removing the board after forming the groove at a removing station.
