DEFINITION

Classification: 156/483

(under subclass 475) Apparatus in which the work travels in a single direction through an opening or passageway, which passageway is of smaller linear dimension than a sheet to be applied to the work and traveling therethrough with the work.

(1) Note. In these patents the work does not reciprocate relative to the passageway, rather it moves through and beyond it. Also, the work moves rather than the bending means.

SEE OR SEARCH THIS CLASS, SUBCLASS:

486+, for apparatus in which the moving member moves past the work to perfect the bending.
