Cutting, power-coating equipment highlighted

Rolf Schlicht GmbH will showcase a variety of pipe, tube, and profile cutting technologies at K, including rotational, orbital, and scissor-type designs. The RS Multicut rotation cutter MC-50 cutting unit and RB-600/100 caterpillar units allow precise cutting of soft and semi-rigid extrudates up to about 50-mm in diameter at highest line speed, with cutting cycles up to about 400/minute in stop/start operation and up to 4000/minute with a continuously rotating knife. Rolf Schlicht says diverse feeding and discharging systems are available and can be built according to customer demands.

Cutting, power-coating equipment highlighted

The RS Multicut orbital cutter is described as a cutting system for precise and fast cutting of semi-rigid and rigid pipes made of plastic, rubber, and plastic composites with rigid or soft aluminum or copper pipe inside, as well as rubber with Kevlar or steel braiding.

Instead of saws or guillotines, the new, patented RS Multicut DC-40 represents a scissor-type cutting system for rigid profiles. Rolf Schlicht says the unit is suited for clean cutting of price strips or scanner profiles in supermarkets, as well as building or furniture profiles made of rigid PVC or similar materials. Short lengths are reportedly cut cleanly and without swarf at maximum line speeds and maximum possible tolerances, with 250 cuts/minute possible.

In addition to cutting equipment, Rolf Schlicht (Stand 3A35) will display its RSC powder-coating machine. The RSC is designed to powder hoses, profiles, strips, and cables evenly, with finely dosed and dust-free powders such as talc or stearate. The company supplies machines from the smallest product diameters up to 200 mm. The RSC electrostatically charges the powder, creating a powerful adhesion to the surface and a very even layer. The company says the electrostatic charge also ensures that no powder falls from the product to outside the dusting chamber. Machines are delivered with 2 or 4 powder nozzles, depending on the application.

Within the machine there is a fluidized powder hopper from which powder is drawn out by pneumatic Venturi pumps and blown through the guns onto the product. For optimal adjustment of the powder quantity, users can adjust the power of the electrostatic charging from 0-100 kV, as well as the powder quantity and the speed of the dust cloud. Depending on the product, the powder gun can also be equipped with different nozzles.

In the machine, there is a fully automatic and maintenance-free filter system that's cleaned by a special process. The filter system ensures that a strong and constant vacuum is generated in the machine, preventing powder from escaping into the ambient atmosphere.

If there isn't enough floorspace to install the machine the company can deliver a free-standing dusting chamber that connects to the machine by hoses. For an extremely fine powdering of slowly running products, an optional fine-dosing device is available to ensure only "a breath of powder" adheres on the strand, according to Rolf Schlicht.

Additional accessories can include an automatic 90-liter powder-refilling hopper; a powder-flow indicator that sounds an alarm if no powder flows through the guns; an automatic electrostatic and pneumatic adjustment to make sure the system's in synch with the extrusion speed; and an interface to connect the machine to the line.
