Abstract

Abstract An installation for subdividing a flat elongated workpiece, such as a stack of wood panels, has a first worktable where the stack is formed and straightened out, a second worktable to which the stack is conveyed so that its longitudinal and transverse edges can be trimmed off and the stack sized by saws mounted adjustably on a displaceable traverse and where a piece or pieces can be cut off the leading end of the workpiece and removed laterally. From thence the workpiece is fed through a station where its longitudinal edges are again trimmed and it is transversely subdivided into a plurality of parts. The parts are fed into separate transport mechanisms which can line them up differently so that a single cut of a transverse saw can sever them producing sections of different lengths.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 320 words
An installation for subdividing a flat workpiece in the form of a stack of elongated sheets comprising: means for displacing a flat workpiece along a generally straight path and including a stacking table for receiving said sheets; first saw means at an upstream portion of said path but downstream of said table for longitudinally cutting said workpiece into at least two parts; second saw means downstream of said first saw means along said path for transversely cutting said parts into respective sections; at least two respective transport mechanisms extending parallel to each other downstream of said first saw means along said path and independently operable to displace said parts through different distances along said path whereby said second saw means can sever said parts into sections of different lengths; straightening means along said table for longitudinally orienting the sheets of said stack; a traverse displaceable along said table and provided with a selectively operable catch engageable with a trailing edge of said stack for displacing same along said table; third saw means mounted on said traverse for movement thereon back and forth athwart saiD table for trimming said stack and for cutting a piece thereoff at a leading end of said stack, said table being provided with an array of rollers at a forward end thereof normally lying below the stack-supporting surface of said table but tiltable upwardly to remove said piece from said table; fourth saw means adjustably mounted on said traverse for longitudinally trimming the workpiece prior to cutting said piece thereoff by said third saw means; fifth saw means for longitudinally trimming the workpiece after removal of said piece therefrom between said first and said fourth saw means, said first, third and fifth saw means being mounted for adjustment transversely to said path, all of said saw means being circular saws; and means for fixing the workpiece during cutting by said second, third, and fourth saw means.
Claim 2
Dependent Claim 320 words
An installation for subdividing a flat workpiece in the form of a stack of elongated sheets comprising: means for displacing a flat workpiece along a generally straight path and including a stacking table for receiving said sheets; first saw means at an upstream portion of said path but downstream of said table for longitudinally cutting said workpiece into at least two parts; second saw means downstream of said first saw means along said path for transversely cutting said parts into respective sections; at least two respective transport mechanisms extending parallel to each other downstream of said first saw means along said path and independently operable to displace said parts through different distances along said path whereby said second saw means can sever said parts into sections of different lengths; straightening means along said table for longitudinally orienting the sheets of said stack; a traverse displaceable along said table and provided with a selectively operable catch engageable with a trailing edge of said stack for displacing same along said table; third saw means mounted on said traverse for movement thereon back and forth athwart saiD table for trimming said stack and for cutting a piece thereoff at a leading end of said stack, said table being provided with an array of rollers at a forward end thereof normally lying below the stack-supporting surface of said table but tiltable upwardly to remove said piece from said table; fourth saw means adjustably mounted on said traverse for longitudinally trimming the workpiece prior to cutting said piece thereoff by said third saw means; fifth saw means for longitudinally trimming the workpiece after removal of said piece therefrom between said first and said fourth saw means, said first, third and fifth saw means being mounted for adjustment transversely to said path, all of said saw means being circular saws; and means for fixing the workpiece during cutting by said second, third, and fourth saw means.
Claim 3
Dependent Claim 16 words
The installation defined in claim 1 wherein said first saw is longitudinally fixed along said path.
Claim 4
Dependent Claim 22 words
The installation defined in claim 2, further comprising means for adjusting said fourth saw means transverse to said path on said traverse.
