Abstract
Abstract Boards to be end to end, bonded, are arranged with corresponding ends in alignment, then profiled and smeared with glue, then shifted longitudinally in accordance with their respectively lengths to bring their opposite ends in alignment for profiling and application of glue, following which, the boards are conveyed individually in alignment to a press for end to end gluing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
Apparatus for fabricating boards from pieces of random length comprising means for assembling a plurality of such pieces of random length side by side with the edges of corresponding ends in alignment, means for profiling said aligned edges, means for restraining said pieces against displacement while said aligned edges are being profiled, means, following the profiling of said aligned edges, for shifting said pieces longitudinally in order of their lengths to bring the opposite end edges of said pieces into alignment, and means for profiling said opposite edges while in alignment.
Claim 2
Dependent Claim
91 words
Apparatus for fabricating boards from pieces of random length comprising means for assembling a plurality of such pieces of random length side by side with the edges of corresponding ends in alignment, means for profiling said aligned edges, means for restraining said pieces against displacement while said aligned edges are being profiled, means, following the profiling of said aligned edges, for shifting said pieces longitudinally in order of their lengths to bring the opposite end edges of said pieces into alignment, and means for profiling said opposite edges while in alignment.
Claim 3
Dependent Claim
22 words
Apparatus in accordance with claim 1, characterized by means for applying a bonding agent to said end edges following the profiling thereof.
Claim 4
Dependent Claim
37 words
Apparatus in accordance with claim 1, characterized by means for cutting through said pieces at right angles to the longitudinal axes thereof to remove unusable ends in preparation for aligning and profiling the edges of said pieces.
Claim 5
Dependent Claim
77 words
Apparatus in accordance with claim 1, characterizzed by said means for assembling a plurality of such pieces of random length side by side with the edges of corresponding ends in alignment as comprising means including a stop, for feeding successive pieces until the forward end of each strikes said stop, means for then laterally shifting each of said pieces in succession onto a table to form a pack with the forward edges of said pieces in alignment.
Claim 6
Dependent Claim
64 words
Apparatus in accordance with claim 1, characterized by means for applying a downward pressure on said pieces of random length, sufficient to overcome frictional drag of the longer pieces against adjacent shorter pieces as said longer pieces are shifted longitudinally to bring their opposite end edges into alignment with the corresponding end edges of adjacent pieces in preparation for profiling said opposite end edges.
Claim 7
Dependent Claim
23 words
Apparatus in accordance with claim 2, characterized by means for assembling said pieces in end to end relationship to bond adjacent ends thereof.
