ABSTRACT:
Plural station apparatus and method is provided for the making of articles of manufacture from sheet material. The first work station performs a first cutting operational step on the sheet material to cut a plurality of precisely cut blanks, and two bending or folding stations perform the finishing step on the blanks to produce the articles of manufacture. The first station is located above the bending or folding stations, and it is laterally offset from each of them. The first station is laterally offset in a first direction with respect to the first work station, and the second is laterally offset in a second direction with respect to the first work station. Two inclined chutes are provided between the output of the first station for allowing the precise blanks to slide by gravity to the input of the first and second bending or folding stations. Thus, the inclined chutes automatically transfer the precise blanks from the first station to the two bending or folding stations solely by gravity. Between the first elevated station and the two bending or folding stations there is provided a directing apparatus which directs a portion of the blanks from the elevated station to the first inclined chute and another portion of the blanks to the second inclined chute. In a specific embodiment, the sheet material is sheet metal, and articles of manufacture are roof flashings.
