Abstract

Abstract Apparatus includes a strip guide table mounted on a fixed base frame for pivotal movement about a pivot point at its discharge end intermediate its sides toward a cross-cut shear in a strip processing line. Means are connected with the entry end of the table for pivoting the table to correct for camber or other irregularity in the strip shape so that the strip approaches the cross-cut shear at right angles after it leaves the guide table. An indicator means is mounted on the base frame in engagement with the guide frame. The indicator mean is calibrated to indicate the variation of the longitudinal centerline of the guide table from the longitudinal centerline of the processing line so that it can be ascertained when the guide table is in proper position for correcting for the amount of camber or other irregularity in the strip and to cause the strip to approach the cross-cut shears at right angles thereto.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 137 words
In a continuous strip processing line the improvement therewith of an adjustable guide table for strip approaching a cross-cut shear in said processing line which comprises a fixed base frame, a horizontally disposed table platform having an entry end and a discharge end, guide means on said platform for guiding the side edges of said strip strip processing means mounted in tandem on said platform, means advancing said strip toward said shear from the discharge end of said table platform, said table platform being pivotably mounted on said base frame about a vertical pivot axis at a point adjacent the discharge end of said table platform intermediate the sides thereof whereby said table platform can be adjustably pivoted laterally about said pivot point to align the strip approaching said cross-cut shear substantially normal to said cross-cut shear.
Claim 2
Dependent Claim 137 words
In a continuous strip processing line the improvement therewith of an adjustable guide table for strip approaching a cross-cut shear in said processing line which comprises a fixed base frame, a horizontally disposed table platform having an entry end and a discharge end, guide means on said platform for guiding the side edges of said strip strip processing means mounted in tandem on said platform, means advancing said strip toward said shear from the discharge end of said table platform, said table platform being pivotably mounted on said base frame about a vertical pivot axis at a point adjacent the discharge end of said table platform intermediate the sides thereof whereby said table platform can be adjustably pivoted laterally about said pivot point to align the strip approaching said cross-cut shear substantially normal to said cross-cut shear.
Claim 3
Dependent Claim 37 words
Apparatus as defined by claim 1 including indicating means on said frame engaged by said table platform to indicate the variation of the longitudinal centerline of said table from the longitudinal centerline of said strip processing line.
Claim 4
Dependent Claim 26 words
Apparatus as defined by claim 1 including means mounted on said frame and connected with said table platform for pivoting the same about said pivot point.
Claim 5
Dependent Claim 22 words
Apparatus as defined by claim 1 including a plurality of wear plates interposed between said fixed base frame and said table platform.
