Abstract
Abstract An apparatus for conditioning the edges of metal strip material which is delivered from a web slitting apparatus or other source wherein grooved rollers are arranged in pairs for receiving one or more strips of the material with the edges along opposite sides of the strips traveling in oppositely disposed, transversely aligned grooves which remove any burrs resulting from the slitting of the material after which the deburred strips are drawn between pairs of oppositely disposed cutter blades having aligned edge cutting formations operative on each side of the strips and finally the strips are passed between pairs of finishing rollers having aligned grooves in which the strip edges are received and which apply pressure sufficient to round the cut edges and smooth the same without appreciable distortion of the strip body.

66 words
An apparatus as set forth in claim 1 wherein each of said grooved rollers is mounted on a vertical axis in a carriage forming member and wherein said carriage forming member is slidably supported in said frame for adjustment laterally of the path of advance of the strip material so as to permit the rollers, each pair thereof to be adjusted toward and from each other.
Claim 7
Independent Claim
167 words

Claim 8
Independent Claim
167 words
An apparatus for conditioning the edges of metal strip material which is delivered from a web slitting apparatus or other source which apparatus comprises de-burring rollers having axially spaced, peripheral grooves, said rollers being arranged in pairs on parallel axes for receiving strips of the material with the edges along opposite sides of the strip material traveling in oppositely disposed, transversely aligned grooves, the grooves in said de-burring rollers being operative to remove any burrs resulting from the slitting of the material, pairs of cutter blades having opposed edge cutting formations between which the strip material is drawn, which edge cutting formations are operative on each side edge of the strip for removing portions of the material, and pairs of finishing rollers mounted on parallel axes and having aligned, axially spaced, peripheRal grooves in which the strip edges are received, which finishing rollers are spaced so as to apply pressure sufficient to work the cut edges and smooth the same without appreciable distortion of the strip body.
Claim 9
Dependent Claim
36 words
An apparatus as set forth in claim 6 wherein said cutter blades each comprise a generally rectangular body portion with oppositely disposed side edges notched at spaced intervals to provide a series of edge cutting formations.
Claim 10
Dependent Claim
53 words
An apparatus as set forth in claim 6 wherein said cutter blades each comprise a plate member having a side edge provided with one or more outwardly opening notches forming a cutting edge past which the side edge of the strip material is drawn and said cutting edge having a generally V-shaped configuration.
