Abstract
Abstract Rotary tool for cutting and/or marking fold lines comprises a cylindrical layer of hard plastic material having embedded therein at least one metal blade of which the outer edge projects from the outer surface of said plastic layer. The blade is locked in place by a metal bar received in a hole in the blade and aligned bores in the plastic layer on opposite sides of the blade.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
Rotary tool for cutting or for marking fold lines comprising: a metal cylindrical core having a longitudinal axis, a cylindrical layer of hard plastic material formed on said metal core, at least one metal blade embedded in said layer of hard plastic material and extending transversely to said longitudinal axis, said one metal blade having an outer edge which projects from the outer surface of said cylindrical layer of plastic and an inner edge on which bears said core, means defining a hole in said one transverse metal blade, the plastic layer on either side of said one metal blade having means therein defining longitudinal bores aligned with said hole, and a longitudinal locking rod extending through both the hole in said one metal blade and through said aligned longitudinal bores in said plastic layer to releasably lock in place said one metal blade.
Claim 2
Dependent Claim
144 words
Rotary tool for cutting or for marking fold lines comprising: a metal cylindrical core having a longitudinal axis, a cylindrical layer of hard plastic material formed on said metal core, at least one metal blade embedded in said layer of hard plastic material and extending transversely to said longitudinal axis, said one metal blade having an outer edge which projects from the outer surface of said cylindrical layer of plastic and an inner edge on which bears said core, means defining a hole in said one transverse metal blade, the plastic layer on either side of said one metal blade having means therein defining longitudinal bores aligned with said hole, and a longitudinal locking rod extending through both the hole in said one metal blade and through said aligned longitudinal bores in said plastic layer to releasably lock in place said one metal blade.
Claim 3
Dependent Claim
50 words
Rotary cutting or marking tool according to claim 1, in which said longitudinal bores have positioned therein metal sleeves embedded in the plastic layer on either side of said one metal blade, and in which said locking rod extends through said sleeves and the hole in said one metal blade.
Claim 4
Dependent Claim
54 words
Rotary cutting or marking tool according to claim 1, in which said outer and inner edges of said one metal blade are arcuate, said one metal blade having further opposite lateral edges which are generally radial with radially inner portions notched inwardly toward one another, thereby reducing the arcuate extent of said inner edge.
