Moulding for building exterior and machine for cutting same

Abstract

A machine for cutting eavestrough into two segments. The machine has a guide plate and a pair of cutting wheels. The guide plate has an opening of a shape similar to that of the cross-section of the eavestrough but slightly larger so that as the eavestrough is fed through the opening, it is guided by the guide plate. The cutting wheels are positioned such that after the eavestrough exits from the opening, its bottom wall passes between the wheels where it is cut.

1 . A cutting machine for cutting a bottom wall of an eavestrough including: a housing; a guide plate; and a pair of cutting wheels rotatably mounted to said housing, said guide plate having an opening of a shape similar to that of the cross-section of said eavestrough and sufficiently large to permit said eavestrough to pass therethrough with minimal lateral movement thereof, said cutting wheels being rotatable about parallel axes, each said cutting wheel having an outer cylindrical surface, oppositely facing side surfaces and a circular cutting edge at the intersection of said cylindrical surface and one said side surface, said cutting wheels being positioned such that after said eavestrough advances through said opening, its said bottom wall passes between said cutting edges with resulting formation of an elongated cut in said bottom wall. 
     
     
         2 . The cutting machine of  claim 1  wherein the bottom wall of said eavestrough is defined by lower and upper oppositely facing elongated surfaces, said cutting wheels being positioned such that the cylindrical surface of one said cutting wheel contacts said lower elongated surface while the cylindrical surfaces of the other said cutting wheel contacts the upper elongated surface. 
     
     
         3 . The cutting machine of  claim 1  wherein the cutting edges of both said cutting wheels lie in the same imaginary plane. 
     
     
         4 . The cutting machine of  claim 2  wherein the cutting edges of both said cutting wheels lie in the same imaginary plane.
