Patent number: 10040583Abstract: The invention comprises a carpet wrapping apparatus. The apparatus comprises a pair of rotatable rollers for supporting a roll of sheet material and for rotating the roll of sheet material supported thereon and a vertically extending curtain disposed adjacent and spaced from the roll of sheet material so that there is a horizontal gap between the curtain and the roll of sheet material when supported on the rollers. The apparatus also comprises a source of pressurized air directed toward the curtain and a plastic film dispenser disposed above the rollers for dispensing a plastic film between the curtain and the source of pressurized air so that the pressurized air blows the plastic film toward the curtain and into the gap. A method of wrapping a roll of carpet with a plastic film is also disclosed.Type: GrantFiled: July 23, 2015Date of Patent: August 7, 2018Assignee: Perpetual Machine CompanyInventors: Adam Paul Smith, Ronald Edwin Headrick, Jr.
