DEFINITION

Classification: 156/477.1

Plural, distinct, sequential bending or folding means:

(under subclass 475) Apparatus in which separate working elements sequentially bend or fold the same workpiece.

(1) Note. The separate means may act on the same area of a workpiece to progressively shape it, or they may act on different areas of a single workpiece.

(2) Note. A means which merely forces workpiece into assembled relation or holds them is such relation is not considered a bending or folding means. Likewise, a means which merely smooths a workpiece portion which has already been bent or folded out of its original plane is not considered a bending or folding means. Thus, this subclass requires at least two folding and/or bending means, acting one after the other, other than whatever means are employed to push, press, hold, or smooth workpiece or workpiece portion. Alternatively, a pushing, pressing, holding, or smoothing means must also perform a bending or folding

function if it is to considered one of the plural sequential means.
