Abstract:
A laminated blade assembly for cutting the insulation of a wire to permit removal of said insulation, said blade assembly including:a stationary member and a movable member which members are formed to contact each other when moved together to cut said insulation, each of said stationary and said movable members including a blade and a pair of wire insulation supports with said blade sandwiched between said supports, each of said supports having an edge of generally rectangular cross section facing a similar edge of a similar support of said other member, a plurality of semi-circular grooves formed in each of said support edges with said grooves extending transversely of said support edges, said grooves being spaced apart from one another longitudinally of said edges, said support grooves of similar diameters aligned with one another, said support grooves forming circular grooves to receive said insulation of said wires when said stationary and said movable members are moved together to cut said insulation, each of said blades having a sharpened longitudinally extending edge facing a similar sharpened longitudinally extending edge of said other blade, and a plurality of semi-circular grooves formed in each of said sharpened edges with said blade grooves extending transversely of said edges, said blade grooves being arranged apart from one another along said sharpened edge so as to align with similar aligned grooves in said supports, each of said blade grooves having a smaller diameter than the support groove with which it is aligned to provide a blade groove extending into its aligned support grooves, said semi-circular support grooves being chamfered along opposite lateral sides at said support edges.
