5 Slitting Knives & cap-lock design

On the Forstner KA-KT-TFF slit and CTL, 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.

Sensitive Material Mode

Sensitive Material Mode

Not only is the coil-selector automatically controlled, but also the adjustment of the upper straightening rollers.

Whenever a new coil is selected, the upper straightening rollers adjust into a new position to ensure the straightening quality.

A special sensitive material operating mode prevents start-stop-lines by the upper straightening rollers and increases the quality of the coil-line enormously. Even a single sheet can be produced without coil-set or marking of the material by the automatically adjusted upper rollers.

6 Straightening Rollers

6 Straightening Rollers

With the 6-roller straightener you can create mark-free, flat sheets. The upper straightening rollers are automatically positioned in front of the sheet and open before standstill to avoid stopping marks.

The straightener has a motor and one pair of infeed rollers, 6 straightening shafts . 110 mm and one pair of out-feed rollers . 70 mm. The upper straightening shafts are also programmable.

The Forstner KA-KT-TFF 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 KA-KT-TFF. The six 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; even plastic film can be applied smoothly and evenly with the fully rubberized rolls. The KA-KT-TFF 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.
