Abstract
PURPOSE:To obtain a spiral body of smaller diameter for its plate thickness by executing bending by pressing a strip plate blank to a mandrel by a forming roller consisting of an elastomer having larger elasticity and executing a 2nd bending by the similar forming roller. CONSTITUTION:Two forming rollers 12, 14 are sufficiently press-fitted to a mandrel 11 and driven at a certain rotary speed in the state of forming circular arcuated contact parts 21, 22. The tip part of a strip sheet blank 23 is fed between the mandrel 11 and forming roller 12. The strip plate 23 is thus sent out in a circular arcuate shape with a 1st bending being executed, guided with being wound on the mandrel 11 by being pressed to the guide face 16 of a guide body 18 and sent into the contact part 22 of the forming roller 14. Now it is sent out by being subjected to the 2nd bending and sent out along the mandrel 11 by being pressed to the guide face 17 of the guide body 19. The spiral body of smaller diameter considering the plate thickness can thus be obtd.
