DEFINITION

Classification: 156/574

(under subclass 538) Apparatus in which a laminating device is particularly adapted (a) to move as a unit over and be supported by the surface of the work to which a lamina is being applied or (b) to apply a lamina to an installed device or portion of a building surface.

(1) Note. The devices of this and the indented subclasses feed or handle only a single lamina in that the base to which the lamina is secured is of such character that it is not handled, being fixed, installed, or otherwise supported. By "feeding or handling" with reference to this subclass, is meant some element other than the means directly applying the laminating pressure. A roller support for a web being applied to a wall as in wall papering would be considered sufficient work handling. Thus the devices of this and the indented subclasses must have at least two elements, (1) a pressing or applying means and (2) a material handling, feeding or guiding means. Under this restriction then, mere applying brushes or rollers with handles would not be provided for in these subclasses in that applying only with no work handling is claimed. Subclass 579 below provides for mere handled applying elements.

(2) Note. The devices of this subclass are controlled manually by the operator and the direction and speed are controlled by him. For devices of the work traversing type in which the law of the machine and its relationship to the work controls the direction search must be made in subclasses 391+.
