DEFINITION

Classification: 228/235.2

Roll bonding:

(under subclass 235.1) Process including applying bonding pressure by the action of a roller*.

(1) Note. In this subclass as well as elsewhere in this class, deforming a work part by a bonding tool simultaneously with bonding is considered to be incidental to the bonding and is accordingly classified therewith. Therefore, included herein is bonding by use of a roller with simultaneous deforming of the work part(s).
