The new Davi plate rolls boast a new yoke design that keeps the rolls more stable under load, enabling more efficient power transfer through the frame and to the workpiece. Also, the frame of the machines has been redesigned to better-integrate the base of the frame, and better transfer stresses during forming to minimize deflection.
coast town of Cesena. Here we visited Promau, which manufactures the Davi line of plate and angle rolls. Davi, Inc. president Alex Soffritti and North America area manager Matteo Rossi provided Andy and me with a lesson in geometry. Specifically, we learned how the firm’s recently improved plate-roll machine provides increased capacity at no increase in purchase price. The firm will introduce its newly minted plate- roll lineup at FABTECH.
“We’ve been selling around 300 machines per year, with 10-percent annual growth, since 2011,” says Sof- fritti. “About 20 percent of those sales are into the North American market. In order to sustain that growth, we invest- ed heavily in the last couple of years in research and development, focusing efforts on improving plate-roll per- formance at no additional cost to the customer. Hence the new machine geometry we brought to the industry late in 2014.”
The new machine lineup, dubbed
is more consistent than with a CO2 laser. Also in action was a panel bender, Model P4Xe-2116, installed in 2012, which we were told can form parts in 2 min. that used to take 25 min. to
form on a press brake.
