  • Wire mesh straightening method and apparatus
    Patent number: 5009545
    Abstract: An improved automated wire mesh straightening apparatus is described. Wheels, casters and a jack enable ease of mobility, jockeying and leveling respectively of the apparatus at a construction site. Hydraulic operation of moving parts provides general fail-safe operation of the apparatus which is also otherwise designed with operator safety in mind. Rolled wire mesh is automatically straightened by a unique application of drive, nip and reaction forces that can be rapidly adjusted to completely straighten wire mesh of varying gauge and under varied environmental conditions.
