Abstract
A channel letter bending machine for bending a return of a channel letter from a stock includes a feeding unit disposed along a path of travel of the stock to be bent for feeding the stock, a flanging unit for forming a flange along one edge of the stock, a notching unit for notching the flange of the stock fed by the feeding mechanism along the path of travel, and a bending unit for bending the stock under the control of the computer control system into the desired configuration for the channel letter shape, wherein the notching unit and the flanging unit are disposed upstream of the bending unit and the flanging unit is disposed upstream of the notching unit.
Claims20
A computer-implemented method of automatically bending a return of a channel letter comprises:
- inputting a desired configuration for the return to be formed into a control computer;
- feeding a stock under the control of the control computer along a feed path including an encoder, a flanging unit, a notching unit, and a bending unit that are arranged along the feed path for the stock, with the flanging unit being located downstream of the encoder and upstream of the notching unit and the bending unit along the feed path;
- selectively forming a flange on the bottom of the stock at desired flange positions on the stock at the flanging unit under the control of the control computer;
- notching the flange of the stock at locations corresponding to a position of bends at the notching unit under the control of the control computer;
- and
- bending the stock at the positions of the bends into the desired configuration for the return at the bending unit under the control of the control computer.
A channel letter bending machine for automatically bending a return of a channel letter from a stock, comprising:
- a control computer for receiving a desired configuration for the return of the channel letter;
- a feeding unit controlled by the control computer disposed along a path of travel of the stock to be bent for feeding the stock, wherein the feeding unit comprises an encoder for determining an amount of stock passing through the feeding unit;
- a flanging unit disposed along the path of travel for selectively forming a flange along one edge of the stock;
- a notching unit disposed along the path of travel for notching the flange of the stock fed by the feeding mechanism along the path of travel;
- and
- a bending unit disposed along the path of travel for bending the stock under the control of the computer control system into the desired configuration for the channel letter shape, wherein the flanging unit is disposed upstream of the notching unit.
