Wire, Strip, Wire Rope and Profile Straightening Rollers
The straightener of cables, strips and wires is performed in steps with successive stages until the final product is obtained. To rationalize the handling between the different steps the material is stocked on reels or on bobbins and takes forms which are not natural.
For every production step, it is therefore necessary to carry out the inverse process by taking the material off its support. At that moment, the straightening operation takes place.
The manufacturing precision of the roller has a major influence on the quality of the final product (wires) as well as on the service life of the rollers. It is therefore essential that the rectified "V" notch on the outer ring has the same geometric characteristics and precision as the rest of the bearing. For this reason, the notch on a C&H roller is precisely machined prior to bearing assembly. Grinding this notch on an assembled standard bearing is risky, as the bearing may be damaged. An acceptable uniformity and geometrical precision can thus not be guaranteed. The service life of the roller is much shorter and the quality of wire drawing suffers accordingly. Among numerous applications using thread guides and straightening rollers, C&H has managed to make a name for itself in the field of specialized wire drawing companies, producing steel cables for the tire industry.
The following machines use the same type of special rollers:
◇Machine tools for fiberglass cables (lawn mowers)
◇Machines for spring manufacturing
◇Machines for metal wires
◇Machines for spooling, un-spooling and rewinding
◇Fine and high precision wire drawing
