  • Method of manufacturing a shingle with reinforced nail zone
    Patent number: RE46177
    Abstract: A method of manufacturing a roofing shingle includes applying an asphalt coating to a substrate to define an asphalt coated sheet, the asphalt coated sheet including a headlap portion and a tab portion. Reinforcement material is applied from a spool to the asphalt coated sheet, wherein the reinforcement material is wound in a waywind pattern on the spool payed out from a roll. The reinforcement material is then secured to the headlap portion of the asphalt coated sheet. Prior to applying the reinforcement material to the asphalt coated sheet, the reinforcement material has a first width. The method further includes shrinking the reinforcement material to a second width narrower than the first width upon securing the reinforcement material to the headlap portion.
