DEFINITION

Classification: 604/365

Containing fiber or material bonding substance:

(under subclass 358) Subject matter wherein a fibrous, or a nonwoven or an extruded component of the collecting means is bound to itself or another component by (a) the application of heat or pressure or the combination of both which because of the intrinsic nature of the material component causes a bonding of the said material to itself or another component; or (b) by the application of a resin compound under heat or pressure or the combination of both to effect a bonding of the material component to itself or another component; or (c) the application of a cementlike compound with or without the use of heat or pressure or the combination of both the effect a bonding of the material to itself or another component to provide mechanical strength or to insure uniform consistency, solidification or adhesion of the material component or components.

(1) Note. Patents in this subclass disclose the use of inorganic and organic compounds to bind fibers or materials together and include the use of adhesives, such as natural starch, cellulose materials and thermosetting resins as binders or glues. Thermosetting resins require the use of heat and pressure and which can not be remelted without destroying its original characteristics. Examples, which are nonexhaustive, include melamines, phenolics, and ureas.

(2) Note. Patents in this subclass usually disclose (a) the application of adhesives to adhere several layers of woven or nonwoven fibers together; (b) the application of adhesive to

bind the edges of a cover wrapper of woven material in overlapping relationship in order to enclose the absorbent layers; or (c) the mechanical bonding of one or more layers of the absorbent pad either by the application of heat or pressure, or the combination of both, to the fibers which because of their chemical composition are bonded together by fusion of at least one layer to itself or another layer.
