摘要： An end-profiler for producing matching finger joints and the like in the ends of timbers and similar structural members, wherein a height-adjustable vise holds such a structural member at a first level for end-profiling by a special profiling cutter arrangement, following which the vice holds a second member, to be end-profiled to fit the first member at a second level offset from the first level by a predetermined amount, the predetermined amount normally equalling one-half spacing between successive convolutions in the profiling cutters; the special profiling cutters arrangement includes a carriage positioned to reciprocate across the end of a timber held in the vise for profiling, and a pair of elongated parallel-spaced counter rotating special ''''abrasive'''' profiling cutters having a plurality of zero-leadthreadlike contours with a shape in profile complementary to the finger joints to be produced, the direction of cutter rotation causing the cutters to cut into the sides of the work rather than the ends of the work, and the stroke of carriage reciprocation being pre-settable to cause each cutter to cut slightly more than halfway through the timber with the cuts merging at the center of thickness of the timber, thereby preventing splintering; a double-ended provision, together with a motor reversal provision, affords means for producing finger joint structure at one end and matching finger joint structure at the other end without resetting the adjustments.
