Filter manufacturing line with rotary pleating machine


Roth offers you personal contacts and above-average availability of spare parts from stock

The RFM type offers:

Rotary folding machines with individual design, specially adapted to the customer's process. These machines are used in fast processes with a high degree of automation. 
The machines are designed depending on which medium is to be pleated or processed by them.

Quick and efficient

Our machine enables precise folding geometries and optimum performance, which is guaranteed by the consistent use of servo motor technology and maximum production precision. Speeds of up to 3,000 pleats/min can be achieved in the production process.
To optimize the production process, our machines can be optionally equipped with various technologies for pre- and post-heating. We also offer curing ovens with afterburner and heat recovery to increase energy efficiency.
