  • Process for machining blanks made of wood or similar materials, such as plastic
    Patent number: 5373879
    Abstract: Elongated wood blanks are fed on a table toward a machining tool such as a planar. The leading end of each blank is engaged by a driven input roller at the upstream side of the tool and advanced by the input roller into engagement with the tool and past the tool. A driven advance roller downstream of the tool then engages each input end to draw the blank past the tool for machining the length of the blank. As soon as the leading end of a finger engages the advance roller, the input roller pressure on the blank is relieved and, when the trailing end of the blank passes the advance roller, the input roller is repositioned to engage the leading end of the next blank.
