Profile: Knudson Mfg.,Inc is a manufacturer of roll forming machinery and roll formed product designs. Our 1770A 5″ K-Style gutter machine utilizes the finest technology available. Our end stop limit switch allows the operator to set a limit switch on the run-out tables to automatically stop at a specific length, allowing repeatable cut lengths without a digital batch controller. This accessory is available for all roofing machines. Our oiler unit feeds a thin film of lubricant onto the sheet edges at the entry guides, minimizing galvanization buildup on the rollers.
