Wire tension is one of the main tasks for best operation of the PM. Due to insufficient tension of the wire the drive roll starts to slip and, as a result, there is more wear on the wire and rolls. The wire stretcher has been designed for correct operation of the wire , which is become longer during operation time and it is necessary to compensate.
The wire stretchers are installed on the lower side of the wire, inside or outside of it, and fixed to the longitudinal beams of the wire frame or to the foundation beam of the machine. They provide a wire strength of up to 8 kN / m by moving the wire roll.
The design of the wire stretcher provides the installation of a doctor blade holder and a shower with brush for cleaning the surface of the stretching wire roll. The wire stretcher consists of levers, a connecting roll, brackets, and drive units (pneumatic cylinders-actuators).
Wire stretcher material: gray cast iron, corrosion-resistant steel.
