Slitting & Sheeting

CNC Autoslitter

To address the issues in folder productivity, safety and accuracy the automated slitter has been developed.

The operator programs the slit widths and lengths required and the autoslitter automatically positions and locks the slitting knives, and feeds out the order in a few minutes. Effectively the processing slits in the same time it would take to for a cut to length system to provide sheets for other equipment to slit.

The machine provides strip to stack of flashings on a marking out table. The machine takes slitting operations off the folder, improving operator safety and increasing productivity.

Material Handling

Decoiler System

The wedge uncoiler has many benefits to the modern rollformer, reductions in coil damage and the factory environment.

The industry standard linkage type uncoilers are afflicted by the mechanics of mechanical advantage, which turns out be no advantage at all. The force required to lift a 6 ton coil from closed, is multiplied as the link approaches 90 degrees, such that a force 10 times that can be applied to the inside of the coil as it is clamped.

The wedge expand uncoiler has a constant mechanical advantage, so the maximum desired clamping force can be set by a pressure relief valve. The spooling of the coil is by electric motor, providing smooth operation that is gentle on coils, keeping them tight and damage free. Hydraulic driven systems require high flow powerpacks that can be  noisy and have problems with heat buildup - leading to inconsistent operation and potential maintenance issues.
