Class Information
Number: 72/51
Name: Metal deforming > By tool-couple pressing together adjacent surface portions of same work (e.g., tube-seamer) > To form longitudinally-seamed tube
Description: Subject matter wherein a tool couple joins together the margins of a piece of work that has been made by deforming metal having thickness, width, and length dimensions, the length being appreciably greater than the thickness of the width, so that side margins parallel to the length contact one another, whereby the product formed is a conduit or pipe having a joint parallel to the length.
