DEFINITION

Classification: 425/363

(under the class definition) Apparatus including a press coupling, at least one part of which has a continuous pressure surface (e.g.., roll, endless belt, etc..) which moves during an operation to reshape, resize, form, or vulcanize an article.

(1) Note. Under the definition the endless surface must be a part of a shaping surface and not merely a moveable support for a male or female shaping member.
