DEFINITION

Classification: 156/578

(under subclass 538) Apparatus having means contacting a lamina with a fluent material which material causes the laminae to be bonded together.

(1) Note. The fluent material may be either an adhesive or adhesive activator. Mere treatment with hot air to activate the adhesive, however, is excluded from this subclass; see subclass 499 for laminating devices combined with means separate from the laminating press for heating the workpiece, and subclass 497 for laminating devices having gas, vapor or flame contact means for the work.

325, for methods of laminating involving the use of a particular adhesive and see especially the notes thereto for the locus of other patents relating to the method of application of fluent materials to the materials.

356+, for devices having means automatically controlling the application of fluent material to the work.

390, for apparatus having coating means which coating means is for some purpose other than or in addition to the means

applying adhesive for laminating. 442, for combined envelop sealing and stamp applying devices.

497, for gas, vapor or flame contact means for the work, which means may render tacky the work or a coating thereon.

509, for means splicing indefinite length or endless bodies end-to-end and having means for applying adhesive to the bodies.

510+, and other appropriate subclasses for laminating devices combined with cutting means and having means applying liquid material to the work.

524+, for such devices that traverse the work.

529, for means projecting the liquid against the work.

530+, for such devices in which the cutter is actuated by or secured to the laminating element.

546, for apparatus joining indefinite length work edge-to-edge and applying adhesive to the work edge.

547+, for means applying fluent material between the layers of indefinite or running length work.

575, for work traversing devices having means for applying a liquid to at least one of the laminae.
