Forstner MST


5 Slitting Knives & cap-lock design

On the Forstner MST slitters, 5 Sets of slitting knives come standard. The shafts are made of polished tool steel and the slitting blades hardened with a Rc45 hardness. The tolerance between the shaft and blades is less that .0005” (.01mm), creating a smooth and easy-to-move positioning of the slitting blades anywhere on the shaft.

The cap-lock design consists of a half moon mild steel that presses onto the shaft by an allen head screw. Because the cap-lock is softer than the shaft, there’s no need to worry about “scoring” the shaft like other designs tend to over time.

The knives have a two side cutting surface, so you can alternate sides and take tension out of narrow slits. The machines come standard with a red with sliver letting on the scale for ease of reading the position of the top blade.

Infeed guide

The infeed guide has four roller bearings (two on each side) to guide metal into the pinch rolls. The roller bearings allow the metal to easily forward and backwards without damaging the edges. This also keeps the material straight as the material is fed into the machine helping to ensure a square cut.

Fully rubberized pinch infeed rollers

The pinch rolls pull material evenly from a decoiler without slipping or twisting. Plastic film can be applied smoothly and evenly with the fully rubberized rolls. Having complete contact while feeding the material ensures full control during slitting. This superior design is much more reliable than segmented rubber rollers.

Raise/lower slitting shaft

As you are slitting and cutting to length a job, the control will stop right before the last piece is about to be cut to length and prompt you to raise the upper slitting shaft. The operator will move the handle up and then the coil will feed to the last position for cutting to length. This allows you to cut the last piece and not waste any material through the slitting knives. We call this the material savings mode. As an option, the raising and lowering of the shaft can be motorized.

The Forstner MST series are massive all-in-one slitting and cut-to-length systems. Forstner’s attention to detail and industry leading innovations have made them a worldwide slit and cut-to-length leader. This attention to detail is on display in the MST.

The four roller-bearing infeed guide rollers, angled to match the loop of the coil from a decoiler, help prevent creasing on soft material like copper, aluminum, and zinc as they to guide materials in the pinch rolls. The pinch rolls then pull the material evenly from a decoiler without slipping or twisting.

The MST series offers so many options and configurations that, regardless of your individual needs, your perfect slitting and cut-to-length system is just a click away.
