Patent number: 9579832Abstract: A method of shortening cycle time required to compression mold shingle or tile is provided, wherein carrier plates are comprised of a surface material and a base, and receive a thermoplastic material, thereon. The roofing material is applied to the carrier plate and the carrier plate is subjected to induction heating, by which its surface material has its temperature raised, without substantially raising the temperature of the carrier plate base, such that the thermoplastic material applied thereto is kept heated in the compression mold. Cooling of the thermoplastic material is by heat transfer from the carrier plate surface material to the carrier plate base, and with both materials having good heat conduction capability. The carrier plate surface material has a high receptivity to being heated by induction heating relative the carrier plate base. The carrier plates are serially delivered through the process, to the compression mold.Type: GrantFiled: October 16, 2012Date of Patent: February 28, 2017Assignee: CertainTeed CorporationInventors: Thomas Kevin MacKinnon, David Nelson, Nolan Loy Son, Trevor Reeve

Patent number: 8574481Abstract: Shingle material, preferably comprising a core with a capstock applied thereto is extruded, preferably by means of a co-extrusion process, onto a series of individual carrier plates, with the shingle material then being severed such that each carrier plate carries its own layer of shingle material thereon and the carrier plates are then delivered to a compression mold, in which the shingle is molded. The carrier plate and shingle is then removed from the mold and carried through a series of hold-down stations, after which the shingle is delivered to a trimmer, where flashing is simultaneously trimmed from its edges. The shingle is then cooled, preferably by sandwiching it between upper and lower retention members, which are cooled via a cooling tower. The retention members impart a curvature to the shingle. The carrier plates are returned via a return conveyor, to be heated, for re-use.Type: GrantFiled: November 29, 2007Date of Patent: November 5, 2013Assignee: CertainTeed CorporationInventors: Thomas Kevin MacKinnon, Douglas Harold Wylie, David George Nelson, William Arno Koegler

Patent number: 8371072Abstract: A molded hip, ridge or rake shingle is provided that is shaped to fit over angled intersecting planar surface of a roof hip, ridge or rake, by making a shingle precursor and draping it in heated condition over a rack having surfaces that have an included angle therebetween to cool and take form, such that portions of the shingle precursor conform to the surfaces of the rack, at a desired predetermined included angle between the shingle precursor portions, to form a hip, ridge or rake shingle with shingle portions having the desired included angle between the shingle portions. The shingle is formed according to the process, and on an apparatus, to produce the shingles that can be applied to a roof, in an array of shingles.Type: GrantFiled: August 31, 2009Date of Patent: February 12, 2013Assignee: CertainTeed CorporationInventors: Larry Wayne Shanes, Thomas Kevin MacKinnon

Patent number: 8337188Abstract: An apparatus for making a shingle, together with the shingle made thereby, is provided, in which one or more thermoplastic materials are extruded or co-extruded to form an extrudate, with the extrudate being cut into a preliminary shingle shape, which is allowed to dissipate heat, and then is delivered to a compression mold, wherein the preliminary shingle shape is compression molded to substantially its final dimensions and is then discharged from the mold and allowed to cool.Type: GrantFiled: March 5, 2010Date of Patent: December 25, 2012Assignee: CertainTeed CorporationInventors: Thomas Kevin MacKinnon, Robert E. Dodd, Joong Youn Kim, Douglas H. Wylie

Patent number: 8257811Abstract: A simultaneously molded plurality of composite shingles or double walled shingles or other substantially planar exterior building products are provided, each being comprised of two or more layers of thermoplastic shingle material, such that a weatherable capstock material is provided outside a core material, in the form of a composite parison that is then blow molded in a hollow mold, to produce novel shingles. Ventilation and/or insulation can be provided to a hollow interior between spaced apart walls of a double walled shingle.Type: GrantFiled: March 28, 2006Date of Patent: September 4, 2012Assignee: CertainTeed CorporationInventors: Joong Youn Kim, Thomas Kevin MacKinnon, Richard Allan Snyder, Husnu M. Kalkanoglu, Gregory F. Jacobs

Patent number: 8206807Abstract: A synthetic roofing shingle or tile is provided, in which a core material is formed, of generally less expensive material, and with a skin material provided, disposed on a plurality of surfaces of the shingle or tile, with the skin material being generally of greater expense and having desirable weather-withstanding qualities.Type: GrantFiled: May 1, 2007Date of Patent: June 26, 2012Assignee: CertainTeed CorporationInventors: Michael L. Friedman, Husnu M. Kalkanoglu, Joong Youn Kim, Thomas Kevin MacKinnon

Patent number: 7934346Abstract: Synthetic shingles are made and treated, such that upper surfaces thereof that are to be weather-exposed in the installed condition, are scuffed, abraded, or scraped in such a manner that different visual appearances occur between abraded zones and unabraded (or lesser abraded) depressions, to enhance the natural-appearing materials that the synthetic shingles are designed to resemble. The shingles and the abrading medium have motion relative to each other. The abrading medium may take on various forms, such as a roller, a brush, a pad, etc. Some portions of the upper surface of the shingle remain unabraded, preferably being those portions that are depressed relative to higher portions of the shingle. The shingle may be of a single layer construction, or a multi-layer laminate.Type: GrantFiled: March 6, 2008Date of Patent: May 3, 2011Assignee: CertainTeed CorporationInventors: Thomas Kevin MacKinnon, Douglas Harold Wylie, John K.
