The aim of this method is to reduce the rejection rate in V-belt using weight stabilization method. Low Belt, Double Jacket, Topping Air, and Base Air are the major rejection in V-belt due to the dissimilar weight in V-belt as the weight plays a vital role in determining the quality of a product and processing parameter such as pressure and heat. The above problems can be rectified by taking weight during the final processing stage of V-belt subsequently it can be segregated depending upon the weight range before curing and then set the curing parameters. Another aspect of taking correct weight every time for the same length & cross section of belt is the regularity of dimension. I vehemently envisage that this method can be used to reduce the rejection rate based on dissimilar weight for any rubber based products not only the V-belt. The benefits of this method is extended below • Sophisticated device are not required to implement this method. • Products having uneven weight can be converted into defect free product. • Rejection rate can be firmly controlled.
