In June 2011 Demax Graphic Arts Group, one of the largest printers in Bulgaria added a SOMA PLUTO II slitter rewinder to its production line.

Founded in 1992, the company now encompasses six facilities: Demax PLC, Rotopress PLC, Bulpap PLC, Demax DPI PLC, Trüb-Demax PLC and Demax-Holograms PLC. The group offers a complete printing services from design concept to delivery using various processes including sheet and web fed offset, heatset, digital, hologram and flexography. This wide range of technologies has established Demax as one of the largest label and security printers in the region.

“We serve a number of different markets including foods, pharmaceuticals, cosmetics, household and industrial,” says Peter Stoyanov of Demax. “We offer a large product portfolio and good quality price to commodity ratios and this is our competitive advantage. I see similar values in SOMA ́s products. Speed, quality, price, ease of operation and stability are the strong points of the PLUTO II. The only thing I would say to others considering the purchase of this slitter rewinder is to order servo driven motors with the machine. We are now regretting that we are limited to using only the friction rings while setting the tension on the upper and lower shafts, however, the performance is still great.”

The PLUTO II is a highly efficient slitter rewinder with integrated unwind unit. Its high mechanical speed up to 550 m/min and ability to process rolls up to 1100 mm wide with diameter of 635 mm make this machine a cost effective solution for slitting paper, film and laminate. Slit roll quality is obtained due to high technology solutions such as rewind tension control with tensometric roller and friction rings – Tensomat II or unwind tension control with pneumatic brake and dancer roller.

The PLUTO II has been installed for three months, clocking up 200 working hours at speeds up to 550 m/min. and has already processed more than 2280 km of material. Demax uses the machine to slit various substrates including paper, aluminium and plastic foils. The company ́s goal is to constantly develop new products and widen the range of materials converted.

“A colleague in the printing industry once told me if you want to work Flexo, you have to be Flexo! By this he meant flexible. I try to stick to this idea every day,” concludes Mr Stoyanov.
