DEFINITION

Classification: 156/539

(under subclass 538) Apparatus in which (a) at least two elements to be bonded to each other are fed or handled or (b) separate portions of a unitary piece to be bonded together are fed or handled in their final associated relationship.

(1) Note. With respect to (b) above the separate portions are generally in their final positional association in that bringing separate portions together into such relationship would probably require bending means for subclasses 443+.

(2) Note. See subclasses 580+ for press structures, per se, with no work handling other than by the press surfaces and see the notes, especially (5) Note, to that subclass for the lines with Class 100 including the line with respect to presses with work handling features.

443+, and see (1) Note above.
