DEFINITION

Classification: 425/90

(under the class definition) Apparatus in combination with means to apply a liquid or fluent particulate solid material (1) to preformed work, (2) between a shaping member and the material being shaped or (3) to work contacting means.

(1) Note. To be included in this and indented subclasses under (1) of the subclass definition the liquid or fluent particulate solid must be applied in such a way that no more than one dimension of the thickness or depth of the layer is controlled by the machine. A means which controls the shape of the applied layer in two or more dimensions are considered molding means and are classified in appropriate subclasses below.

(2) Note. To be included under (2) or (3) of the definition the material must be applied for the purpose of conditioning the work contact means or the product, (e.g.., parting, release, or lubricating materials, etc..). Means applying materials which are intended to adhere to the product and contribute to the overall shape and structure are considered molding means and are classified in appropriate subclasses below.

(3) Note. Excluded from this and indented subclasses are patents claiming means for adding, blending or mixing a liquid, particulate, or pulverulent material within a feeding means or mixing means upstream of a shaping means. Such devices are classified in appropriate subclasses below. See especially subclasses 200+.
