Abstract: A web of jacketing material is unwound from a reservoir thereof and conveyed at constant speed. A double sided, pressure-sensitive adhesive strip, having one side protected by a removable sheet covering, conveyed in a direction normal to that of the jacketing material, is cut to predetermined lengths, positioned subjacent to and then applied across the width of the jacketing material at predetermined intervals. The jacketing material is sheared into sections by making cuts across the material along the middle of the adhesive strip and at a line midway between adhesive strips.

Abstract: In the manufacture of glass fibrous products wherein gaseous streams of fibers are directed through conduits from a generally horizontal direction downwardly in a generally vertical direction towards a moving collection surface, the improvement wherein forming tubes are telescopically associated with downwardly sloping portions of the conduits and supported so that the forming tubes may be positioned at various distances above the collection surface and at various angular orientations relative to the moving collection surface. Also, the shaping of the forming tubes allows additional gaseous streams of fibers to be produced. By selectively manipulating the height and orientation of the forming tubes, the ability to produce a uniform deposition of material onto the moving collection surface is greatly improved. A method and apparatus for the application of binder is also disclosed.

Abstract: A method and apparatus for collecting fibrous material, particularly small diameter glass fibers, i.e. within the range of 0.05 to 2.60 microns, from a gaseous medium in an efficient, environmentally sound manner is disclosed herein. The apparatus includes a collection chamber which partially encloses a rotating drum having a perforated peripheral surface and having a fine mesh collection screen superimposed thereover. The drum is positioned in such a manner that the screen intercepts a gaseous stream of fibers, e.g. glass microfibers. A suction force established interiorly of the peripheral surface of the drum draws the gaseous stream through the collection screen in order to thereby continuously collect a layer of fibers upon a portion of the rotating screen. The layer of fibers is removed from the drum and wound on a mandrel at a point outside the collection chamber. In a preferred embodiment of the present invention the drum surface is cleaned of any residual fibers.
