Abstract
An improved apparatus for manufacturing roofing shingles having multiple ply appearance, in which an elongated strip of a dry organic or mineral material previously saturated in an asphalt tank and with at least one uniform longitudinally continuous strip of a first coating of granules is fed into the apparatus. The apparatus automatically and repeatedly applies spaced apart bands of varying widths of an adhesive material onto the first coating of granules. A second coating of granules is then automatically applied by the improved apparatus to the asphaltic bands. The application of the adhesive bands and the subsequent granule distribution are synchronized so that the granules are distributed only upon the bands of adhesive.
Claims16
An improved apparatus for manufacturing roofing shingles from dry roofing material comprising, means for continuously feeding dry roofing material into said apparatus, an asphalt saturation tank for receiving, saturating and coating said dry material with asphalt, means for applying a first continuous coating of granules to said saturated and coated material, means for cutting said material into roofing shingles of a given length and a given width, wherein the improvement comprises, means disposed between said means for applying a first coating of granules and said cutting means for automatically applying a repeated series of spaced apart bands of granules to said first continuous coating of granules, said series of bands having various widths and periodically applied along said first continuous coating at a predetermined periodicity, such that said series of bands are applied to said first coating of granules over a length different than said given length of shingle, whereby varying portions of said series of bands will be present on each of said given length of shingle.
An improved apparatus for manufacturing roofing shingles from dry sheets of organic material comprising, means for continuously feeding dry sheets of material into said apparatus, and asphalt saturation tank for receiving and saturating said dry material with asphalt, means following said asphalt tank and facing both surfaces of said saturated material for applying a coating to said saturated material, means for applying a continuous coating of granules to the top surface of said saturated and coated material, means following said first granule applying means for cutting said material into roofing shingles of a given length and a given width, wherein the improvement comprises, means disposed between said means for applying a coating of granules and said cutting means for automatically applying a repeated series of spaced apart bands of granules to said first coating of granules, said series of bands of granules having various widths and periodically applied along said first coating of granules at a predetermined periodicity such that said series of bands are applied to said first coating of granules over a length different than said given length of shingle, whereby varying portions of said series of bands of granules will be present on each of said given length of shingle;
- said means for applying said series of bands of granules comprises,
- (a) means for conveying material having a first coating of granules thereon into and through said means for applying said series of bands of granules,
- (b) container means for storing adhesive therein,
- (c) adhesive applying means operably associated with both said conveyor means and said container means for automatically, periodically, applying spaced apart bands of adhesive of varying widths to said strip of a first coating of granules over a length different than said given length of shingle,
- (d) means operably associated with said conveyor means and said adhesive applying means for controlling the operation of both said conveyor means and said adhesive applying means,
- (e) a frame disposed such that material having a series of spaced apart bands of adhesive affixed to said strip of said first coating of granules passes therebelow,
- (f) a plurality of granule supply conduits mounted to said frame adapted to supply granules to and upon said spaced apart bands of adhesive,
- (g) gate means operably associated with said conduits to control the flow of granules through said conduits,
- (h) means operably associated with said gate means for controlling said gate means, and
- (i) means operably associated with both said means for controlling the operation of both said conveyor means and said adhesive applying means and means for controlling said gate means for synchronizing and controlling the operation of both said means for controlling the operation of both said conveyor means and said adhesive applying means and said means for controlling said gate means whereby said granules are automatically distributed only upon said bands of adhesive.
