Abstract
Abstract A method and a device are disclosed for joining wooden strips set at an angle, such as the wooden strips employed for picture frames and the like. The metal fasteners are chevron shaped metal sheet blanks whose respective ends are integral with two parallely running bands. The fasteners have teeth projecting perpendicularly to their common plane, said teeth being intended to be driven into the wood strips. A hydraulic punching press is provided which, once the wood strips set at the desired angle have been positioned on the press bench, drives a punch which severs each chevron-like fastener individually and drives the relevant teeth into the wood strips to be joined.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
69 words
A method for joining wooden strips together, characterized in that it employs a belt formed by a succession of planar metallic members forming an angle in their own plane and having teeth orthogonally projecting therefrom said members being integral at their ends to two strips of the same metallic material, wherefrom each of said members is severed by stamping and subsequently driven into the wooden strips to be joined.
Claim 2
Independent Claim
69 words
A method for joining wooden strips together, characterized in that it employs a belt formed by a succession of planar metallic members forming an angle in their own plane and having teeth orthogonally projecting therefrom said members being integral at their ends to two strips of the same metallic material, wherefrom each of said members is severed by stamping and subsequently driven into the wooden strips to be joined.
Claim 3
Dependent Claim
57 words
A means to be employed in the method according to claim 1, characterized in that it comprises a belt formed by a succession of planar metallic meMbers forming an angle in their own plane and fitted with teeth projecting orthogonally therefrom; said members being integral at their two ends to two strips of the same metallic material.
Claim 4
Dependent Claim
85 words
A device for severing from each other said members and for driving them into the wooden strips to be joined, according to claim 1, characterized in that it comprises guiding means for said strips to which the ends of each member are affixed, means for imparting a stepwise forward motion to said belt in a severing and driving-in station, and means for severing each member out of said strips and driving it subsequently into the wooden strips to be joined, as positioned in said station.
