ABSTRACT:
A method and apparatus for acting on angle irons or the like. A vertical stack of angle irons is provided and the angle irons are fed one at a time to a punching position. At the punching position a hole of selected size is punched in the angle iron, and the angle iron is fed from the punching position in a linear direction of movement to a cutting position. The length of the angle iron to be cut is determined by measuring the length of angle iron in the direction of movement past the cutting position, and the angle iron is cut at the cutting position. Each cut angle iron is removed from the cutting position in a direction normal to the linear direction of movement of the angle iron to the cutting position. A computer may be provided for controlling operation of all motors to affect selection of punch sizes and cutting blades, and to affect operation of all the power mechanisms.
