Innovative Cutting System from Roth Composite Machinery

Roth Composite Machinery will present an innovative, swiveling length cutting system for its knife pleating machines for the production of filters at FILTECH 2023.

The new length cutting system enables an increase in production output, as the maximum width of the filter material is fed into the machine and the filters are cut in individual widths lengthwise to the material web.

“If our customer wants to produce tencentimeter-high filters, he will get ten times the amount of filters in one production run with a filter material of one meter width compared to production with only one filter height. Therefore, length cutting systems have established themselves in the market. For better and riskfree handling in the production process, we have further developed the positioning of the cutter in the machine. This brings a number of advantages for our customers,” said Senior Sales Manager at Roth Composite Machinery, Winfried Schäfer.

The machine design developed by Roth

Composite Machinery features the length cutter directly in front of the folding knives. “For safety and ergonomic reasons, we have designed the complete infeed table, including the cutter, to swivel. The operator can swivel the table by 90 degrees in a position provided for this purpose, so that the cutter practically swings out of the machine. The swivel position is deliberately chosen at the center of gravity of the infeed table so that the swiveling process can be carried out easily,” Schäfer said.

The operator can make the necessary adjustments on the length cutter directly and without physical exertion. Alternatively, the knife shafts could simply be removed by loosening two screws each and replaced with preset shafts. This saves adjustment and setup times, Schäfer continued.

Compared to standard cutting systems, the new process from Roth Composite Machinery increases the safety of the machine operator, as adjustment work is considerably simplified. The upper cutter in particular has sharp knives that pose a risk of injury to the operator during machine set-up. www.roth-composite-machinery.com

The cutting system is based on the principle of scissor cutting and works with round lower and upper knives.

Founders of this Award-Winning Start-up Stayed True to Mission and Proved Critics Wrong

When Dr. Serene Almomen, CEO of sensor-based monitoring systems leader Attune (formerly Senseware), and co-founder Dr. Julien Stamatakis first founded their company, they certainly had a vision for what their company would hopefully become, but today, Attune has made a name for itself by developing a unique air quality monitoring solution platform with 45 patents, that is causing industry experts to take notice. International Filtration News connected with Almomen to learn more about her ever-expanding company and the impact it is having on challenges within the air filtration space.
