DEFINITION

Classification: 156/502

(under subclass 349) Apparatus uniquely adapted for joining (a) the butt ends of bodies of indefinite extension, or (b) the butt ends of a flexible body to which the ends have been brought into juxtaposition whereby an endless band of article is formed.

(1) Note. With respect to both (a) and (b) above, the periphery only of the workpieces are handled to bring the

parts into assembled relationship and thus the length can be continuous or of any desired amount.

(2) Note. With respect to (b) above the device is usually for joining the ends of a workpiece to form an endless belt. These devices do not have the means bending the workpiece into the loop to bring the ends together, such subject matter being found in subclasses 443+ above with other patents relating to bending means. Insofar as the joining or work holding features therefor, they may be no claimed structural differences between (a) and (b).

(3) Note. Means to merely hold plural pieces (while glue is disclosed and/or claimed as setting) for the purpose of assembly is not considered appropriate for this and indented subclasses. However, the inclusion of claimed means to move or guide plural pieces together for the purpose of assembly will be placed in this or indented subclasses.
