The roll slitter machine type TRH is designed to cut rolls of abrasive paper and cloth and to rewind them with grain both inside and outside. TRH is a very high-performance machine which is suitable for the continuous process of heavy jumbos. It can moreover cut from full jumbo width rolls of 20-25 mm width for the production of flap-discs, flap-wheels and economy rolls.
