A method of treating a conventional vee-belt (having a polyester reinforcement) to stabilize the belt at a required nominal length includes the steps of pre-vulcanizing the otherwise completed belt on a heating drum around which the vee-belt is passed without tension being applied. The belt is prepared for vulcanization under tension so as to eliminate shrinkage caused by the pre-vulcanization step and bring the belt back to its original length. Subsequently the belt is stretched over two rollers under a standard load and when the required length is achieved, is given a permanent set by immediate cooling.
