CA 2234622

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 material along a material feed path of the machine. A notching station (30) 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 (40) forms the flanges on the edge of the material, when desired. A bending assembly (60) bends the strip of material into the desired form. The material is cut at a cutting station (50) immediately preceding the bending assembly (60).

Cintreuse de pliage automatique d'un matériau pour la formation de l'enveloppe extérieure d'une lettre en relief, dans laquelle on introduit la configuration voulue de la lettre en relief dans un ordinateur. L'ordinateur commande l'alimentation de la bande de métal dans la machine le long d'un chemin permettent d'alimenter la machine. Un poste d'entaillage (30) procède à l'entaillage éventuel du bord dudit matériau afin d'y former des flans et de le plier. Un poste consécutif de formage (40) de flans permet à la demande de façonner des flans sur le bord du matériau. Un dispositif de pliage (60) plie la bande de matériau à la forme voulue. Un poste de découpe, situé juste avant le poste de pliage, permet de découper le cas échéant le matériau.
