Webtek UK stock a range of Tungsten Carbide razor slitting knives and Teflon cutting blocks for use on corrugating machine slitting units which do not utilise a liquid lubrication for the prevention of starch sticking to the knives. Razor knives and Teflon cutting blocks are normally available ex-stock for the popular Fosber Twin 400 machine and some types of MHI machines. If we do not hold stock for your specific machine send us a sample and we will be happy to quote.
