Unwinding and straightening systems for the three longitudinal wires and the two continuous diagonal wires Two roller type straightening devices for the two continuous diagonal wires
Installed power is only 250KVA which is the lowest in the industry, low cost.
Active wire payoffs reduces feeding resistance which is workable with different size wires.
Passive feeding device is high speed with little length accuracy, high stability.
Anti-twist device, anti – lateral bending device and groups of straightening devices working together ensures wire straightness is lower than 5mm/m.
Mechanical shearing system are being used which reduce cost of maintenance and replace of hydraulic oil, then there is no problem caused by pollution of hydraulic oil and noise.
Simple structure of collecting equipment, low cost maintenance.
Mainly used in housing industry, workable with no foot truss girder.
