ABSTRACT:
In a machine for automatically bending a material into the outside skin of a channel letter, a desired configuration of the channel letter is input into a control computer. The computer controls the feed of the strip of metal into the machine for the bending of the metal into the outside skin. Feed assemblies feed the material along a material feed path of the machine. A notching station notches the edge of the material where necessary for purposes of forming flanges in the material and bending the material. A subsequent flange forming station forms the flanges on the edge of the material, when desired. A bending assembly bends the strip of material into the desired form, with the bending arm moving from one side to the other of the material as necessary. The material is cut at a cutting station immediately preceding the bending assembly when the length of the material needed for the formation of the outside skin has been fed to the appropriate point at the cutting station along the material feed path.
