Abstract:
1. A bending apparatus comprising: a transferring unit for transferring a metallic rule through a passage formed by a guide, said passage defining a longitudinal axis; a folding unit having first and second rotary bodies spaced to receive said metallic rule therebetween; and a pair of bending fingers including a first bending finger and a second bending finger, said pair of bending fingers supported to revolve and move in a direction substantially transverse to the longitudinal axis for applying force against the metallic rule passing through the guide, said pair of bending fingers positioned adjacent to the guide, and for bending the metallic rule to desired angles, wherein each finger of said pair of bending fingers is each configured for arcuate rotational motion relative to said guide from a first position toward at least one second position to bend a portion of said metallic rule, and wherein each of said pair of bending fingers separately rotates about a single rotational axis relative to said guide.
