DETAILED DESCRIPTION

[0016] Referring now to the Drawing, wherein like reference numerals designate like or corresponding elements throughout the views, and particularly referring to FIG. 1, there is shown an apparatus for forming fascia molding 10. The apparatus 10 includes an elongate housing or enclosure 12 having opposite front and back ends. Apparatus 10 can be supported on legs 13 as shown, in a fixed position, or carried on a mobile platform (not shown) such as a trailer or within a truck for transportation to/from a work site.

[0017] Strip material 14 from a roll or coil of stock 16 is fed into the front end of the enclosure 12. The flat strip material 14 can comprise sheet metal, such as aluminum, which may be coated on one side 14a and uncoated on the other side 14b. Material 14 comprises bendable or malleable sheet material like that used in forming gutters and the like. In the preferred embodiment, the material 14 comprises aluminum about 12 to 15 inches wide and about 0.027 or 0.029 inch thick, coated with paint or vinyl on side 14a and uncoated in mill finish on the opposite side 14b. Any suitable material or coatings can be used.

[0018] The coil of stock 16 can be supported on a stand (not shown) in front of the enclosure 12, or mounted on top of the enclosure. In the preferred embodiment, the stock coil 16 is supported so that the material 14 is fed into the enclosure 12 with the coated side 14a facing up, as shown.

[0019] Within the enclosure 12 of the apparatus 10 are a motor and drive mechanism 18 and a guide and roller arrangement 20 defining a feed path for advancing the material 14 through the machine. A shear or blade mechanism 22 is located at the front end of enclosure 12 for cutting the fascia molding 30 to length as it comes out. The shear mechanism 22 is manually actuated by handle 24.

[0020] The drive mechanism 18, guide and roller arrangement 20 and cutter mechanism 22 of apparatus 10 are constructed and arranged in a new and unique combination from elements similar to those found in prior gutter machines. For example, see U.S. Pat. Nos. 3,529,461, 4,899,566, 5,551,272 and 6,931,903 to Knudson, the entire disclosures of which are hereby incorporated by reference herein.

[0021] FIGS. 2-9 illustrate the various steps in forming the flat material 14 into the fascia molding 30. The first step involves roll forming a longitudinal curved shape or profile 32 inward from one longitudinal edge 33. Reference numerals 33 and 36 designate the opposite side edges of profile 32. In the preferred embodiment as shown, the profile 32 is an oggee shape, although a crown profile, cove profile or other suitable profile of any desired shape can be used.

[0022] After the profile 32 has been formed, material 14 is then folded or bent in one direction upwardly along a longitudinal fold line 34 at one side of profile 32, as best shown in FIG. 3. The portion of material 14 thus folded or bent upwardly includes profile 32 and the flat portion adjacent to edge 33 between the profile and edge 33.

[0023] After the portion of material 14 inward from edge 33 has been folded in one direction upwardly, the material is bent downwardly in the other direction along longitudinal fold line 38 about 90 degrees to form an upper attachment flange 40 along the upper edge 33 of the fascia molding 30.

[0024] The portion of material 14 along the opposite edge 42 is also bent upwardly in one direction about 90 degrees along fold line 44 and then bent back downwardly in the other direction about 90 degrees along fold line 46, as best seen in FIGS. 4 and 5.

[0025] The flat and profile portions of material 14 inward from the edge 33 are then bent downwardly about 90 degrees along longitudinal fold line 48 and then bent back upwardly about 90 degrees along longitudinal fold line 50 to form the flat side of the fascia molding 30, as best seen in FIGS. 6 and 7.

[0026] The distance between fold lines 46 and 50, defining the flat side of the fascia molding 30, can vary depending upon the particular building application.

[0027] Meanwhile, the portion of material 14 along the opposite edge 42 is bent inwardly about 90 degrees along longitudinal fold line 52 and then bent back downwardly about 90 degrees along longitudinal fold line 54 to form a lower attachment flange 56 of the fascia molding 30, as best seen in FIG. 9.

[0028] FIG. 11 shows a typical installation the fascia molding 30. In the preferred embodiment, the lower attachment flange 56 is secured by fasteners 58 to wall sheathing 60, behind the upper edge of siding 62. The upper attachment flange 40 is secured by fasteners 64 to the outer edge of the roof sheathing 66.

[0029] FIG. 10 shows a modified fascia molding 30a, similar to fascia molding 30, except that the lower attachment flange 56 has been cut off along fold line 54, in order to provide support for soffit 68 under the roof eave, as shown in FIG. 12.

[0030] Although a particular sequence of steps have been shown and described herein for manufacturing the fascia molding 30, another sequence of steps in a different order could be used. Also, some steps could be combined and/or carried out simultaneously instead of sequentially, if desired.

[0031] If desired, longitudinally spaced-apart, holes or perforations (not shown) could be provided in the flanges 40 and 56 for receiving fasteners 64 and 58, respectively. Such holes or perforations would be elongated to allow for thermal expansion and contraction. Also, edges 33 and 42 could be folded back upon themselves for additional rigidity and reinforcement of flanges 40 and 56, respectively.

[0032] FIG. 13 shows an apparatus for forming fascia molding 70 incorporating a second embodiment of the invention herein. Since apparatus 70 incorporates components substantially similar to apparatus 10, the same reference numerals have been used, but with prime () notations for differentiation.

[0033] Instead of forming fascia molding 30 in continuous fashion from coil 16, which is then cut to length as desired with shear 24, apparatus 70 utilizes precut sheets 72 of material 14 to form sections of fascia molding in precut lengths. Otherwise, the manufacturing steps are the same. In the preferred embodiment, the sheets. 72 of material 14 are precut in any suitable length, such as 10, 12, or 16 feet long.

[0034] If desired, longitudinally spaced-apart, precut holes or perforations 74 can be provided along the opposite edges of each sheet 72 before forming the flanges 40 and 56 in fascia molding 30, as shown in FIG. 14.

[0035] Similarly, as FIG. 15 shows, one of both of the ends of each sheet 72 can be precut in a predetermined profile to facilitate joining two sections of fascia molding 30 together. For example, the ends of sheet 72 can be precut to facilitate making a mitre joint with and between two sections of fascia molding 30 during installation.

[0036] From the foregoing, it will be appreciated that the present invention comprises an apparatus and method for forming fascia molding having several advantages over the prior art. One significant advantage is the ease of installation when the fascia molding can be made in continuous fashion and cut to length according to the particular building application, thus avoiding the seams and piecemeal approach characterized by the prior art. This results in efficiencies and cost savings in manufacturing, installation and maintenance. Other advantages will be evident to those skilled in the art.

[0037] Although particular embodiments of the invention have been illustrated in the accompanying Drawing and described in the foregoing Detailed Description, it will be understood that the invention is not limited only to the embodiments disclosed, but is intended to embrace any equivalents, modifications and/or rearrangements of elements falling within the scope of the invention as defined by the following Claims.
