Abstract
PURPOSE: To produce the formings of intricate irregular shapes with good accuracy and decrease the restrictions in the design of rolls by subjecting the strips run out from a pair of uncoilers to cold roll forming, and superposing and joining the same.
CONSTITUTION: From a pair of uncoilers 1, 1, respectively each one sheet of metal strips 2, 2 are run out simultaneously, are passed through relaying devices 3, 3 and are further passed through a looper 4. The looper 4 is for stocking the strip for the time when the strips 2 are relayed and connected by the devices 3, in order to avoid stopping of cold roll forming machines 6 during said time. Next, the strips are passed through the cold roll forming machines 6. A pair of the strips 2, 2 are formed to an irregular shape by the roll stand 5 in the front part and a pair of these formed strips 2, 2 are superposed above and below, are caulked and connected by the roll stand 7 in the rear part, whereby the formed products of intricate irregular shaped sections are obtained.
