Definitions
- the invention relates to batts of mineral fibers for use primarily as a ceiling and wall structures and to the method of making the same.
- the invention provides a fibrous insulating product which may be satisfactorily manufactured into rolled packages of a width dimension at least half of the width of the finished product. More specifically, the invention contemplates splitting a low density continuous pack of bonded fibers by use of any suitable means such as a band saw which cuts clearly through the light body of fibers and leaves fiat clean surfaces on both sides of the cut. In the event the pack were two inches in thickness, the splitting is preferably accomplished at the center pack to produce two sections each approximately one inch in thickness. The two sections are then separated and a folded splicing paper is inserted between two adjacent edges of the respective sections and adhesively secured thereto.
- any suitable means such as a band saw which cuts clearly through the light body of fibers and leaves fiat clean surfaces on both sides of the cut.
- the splitting is preferably accomplished at the center pack to produce two sections each approximately one inch in thickness. The two sections are then separated and a folded splicing paper is inserted between two adjacent edges of the respective sections and adhesively secured thereto.
- the splicing paper is adhesively secured along the edge portion of the upper surface of the lower section, while the sections are separated, and then adhesively secured along the respective edge portion of the lower surface of the upper section by bringing the two sections into superposed contacting relation.
- the thus formed product is then rolled and packaged.
- the product is unrolled, cut to the desired length, and unfolded preparatory to use.
- the unfolded product has a width dimension which is double the width of the 3,582,421 Patented June 1, 1971 folded product and is thereby capable of being used to span greater areas.
- the size of the fibers used in fabricating the product is determined by the type and control of the forming equipment utilized. Such equipment conventionally employs air, steam, or combustion gases for attenuating molten threads of glass issuing from small orifices.
- the fibers are collected at the forming station in pack form with an uncured binder component dispersed throughout.
- a binder composed of a combination of melamine and phenol formaldehyde resins in proportion of roughly one to two, has acceptable strength in fire resistant characteristics.
- Other fibrous glass bonding agents are well known and would be quite equally effective for use. These may include epoxy, urea, and polyester resins, and run in an amount dependent upon the balance desired between sturdiness and fire protec tion.
- the pack of fibers with the uncured binder dispersed throughout is conventionally caused to be passed through an oven, while under compression between parallel spaced flights of a pair of conveyors.
- the heat applied within the oven cures or sets the resin binder, and the pack is thus permanently established in its compressed state.
- FIG. 1 is an isometric diagrammatic view of a section of a production line capable of carrying out the steps of the invention and producing the fibrous product of the invention
- FIG. 2 is a perspective view of the product of the invention being unrolled from the final package and being cut into desired lengths for use preparatory to the installation thereof.
- FIG. 1 a continuous pack 10 of a bonded fibrous glass material which has been previously compressed between conveyor flights and dimensionally stabilized by the curing of the binder content in an oven (not shown).
- the density of the pack be set between one and one quarter, and two and one quarter pounds per cubic foot, and the binder content be present in a proportion of twelve percent by weight.
- These specifications are satisfactory for relatively thin products intended for acoustical insulation use.
- the specifications can vary depending on the ultimate intended use of the product.
- the pack 10 may need the extra strengthening provided by increasing the density to as much as four pounds per cubic foot, and the binder content as high as sixteen percent.
- the compressed pack delivered to the band saw 12 may have a thickness of two inches, for example, and as being split by the saw 12 into two equal sections 16 and 18 nominally one inch in thickness.
- a pack three inches thick may be split into two or three sections depending up on the thickness and the desired width of finished product, as will be explained in greater detail hereinafter.
- each section retains one side or face of the pack 10.
- the strengthening properties of an original side of the pack due to the extra binder therein and the ironing effect of the compression under heat, contributes to maintaining the material against sagging when it is suspended in a ceiling installation. Accordingly, whatever the thickness of the pack 10, it has been found advantageous to split the pack once to produce only two sections.
- the upper split section 16 of the pack 10 is caused to travel upwardly over a pair of horizontally spaced apart guiding carry-over rollers 20 and 22.
- the lower section 18 is caused to travel over a conveyor 24.
- Located downstream of the band saw 12 there is disposed a liquid adhesive applicator head 26 which is connected to an adhesive reservoir 28 through conduits 30 and 32.
- the conduit 32 may be provided with a fluid flow control valve 34 to meter the flow of liquid adhesive material to the applicator head 26 from the reservoir 28.
- the applicator head 26 applies a line 35 of adhesive material to the marginal edge portion of the upper surface of the lower section 18.
- a guide channel 36 Downstream of the applicator head 26 is a guide channel 36 adapted to guide a web of folded flexible material 38 which is delivered thereto from a supply roll 40. It has been found that the material 38 can be papers, as well as other flexible sheet materials.
- the web of folded material 38 is guided in its travel from a supply roll 40 to the guide channel 36 by a pair of spaced apart guiding idler rollers 42 and 44.
- the guide channel 36 is formed with a slot 46 through which the web of folded material 38 travels and is brought into intimate contact with the line 35 of adhesive material on the upper surface of the lower section 18 of the pack 10.
- the web of folded material 38 is applied to the lower section 18 in such a fashion that the fold line or folded edge faces outwardly and is adjacent the outer edge of the lower section 18.
- Another liquid adhesive applicator head '48 is located downstream of the applicator head 26 and is connected to the reservoir 28 through conduits 50 and 32.
- the conduit 50 may be provided with a fluid flow control valve 52 to meter the flow of liquid adhesive to the applicator head 48 from the reservoir 28.
- the applicator head 48 is effective to apply a line 54 of liquid adhesive to the upper surface of the web of folded material 38 which has previously been adhesively secured to the lower section 18.
- the liquid reservoir 28 is provided with suitable pumping means diagrammatically illustrated in FIG. 1. In the preferred method it has been found desirable to employ a quick drying liquid adhesive, it being understood that other adhesives could be used where the manufacturing techniques permit.
- the upper and lower sections 16 and 18, respectively, are caused to be joined by being directed between a press roller 56 and the conveyor 24.
- the coaction of the conveyor 24 and the press roller 56 effectively forces the marginal edge of the lower surface of the upper section 16 into intimate contact with the adhesive line 54 formed on the upper portion of the web of folded material 38-.
- the press roller 56 is vertically adjustable to accommodate material of various thicknesses.
- the upper and lower sections of the fibrous material are joined together by the web of folded material 38 to form a finished insulating product which is typically rolled into a package 60, illustrated in FIG. 2.
- the rolled package 60 may be transported to the user where it is unrolled and cut into the desired lengths by the mechanic performing the installation.
- the pack 10 could be split into multiple sections so long as the alternate adjoining edges are suitably spliced together in a manner such as illustrated and described in respect of FIG. 1.
- the web of folded material 38 could be made of a Width dimension to span the entire surface formed by splitting the pack 10. In such an instance, the surface containing the folded material would be exposed to the interior of the associated room in which the finished product is being installed.
- plastic films such as, for example, polyethylene, plasticized polyvinyl chloride, polyvinylidine chloride, nylon, polycarbonate and polyvinyl fluoride may be utilized in lieu of paper.
- Such materials could be readily adhered to the fibrous material by adhesive materials which would include elastomeric compositions such as solutions, dispersions, or emulsions of butadiene-styrenes, nitriles, or neoprenes with a fire-resisting component therein.
- adhesive materials which would include elastomeric compositions such as solutions, dispersions, or emulsions of butadiene-styrenes, nitriles, or neoprenes with a fire-resisting component therein.
- Various other thermoplastic, thermosetting and other elastomeric adhesives may give good service for joining the web of folded material 38 to the split sections of the pack.
