Abstract:
A device to form spirals in a coiling machine for rolled stock located downstream of a rolling train provided with drawing rollers, wherein said coiling machine comprises:(i) a reel able to rotate around an axis of rotation, wherein said device comprises a guide element for guiding said rolled stock in a segment between said drawing rollers and said coiling machine;(ii) first translating means connected to said guide element to displace at least a first end of said guide element in a direction substantially parallel to said axis of rotation of said reel;(iii) second translating means connected to said guide element to positively displace at least said first end of said guide element on a plane substantially perpendicular to said axis of rotation of said reel; and(iv) wherein said first translating means are provided with guide means able to guide at least a section of said rolled stock for maintaining the latter constantly perpendicular to said axis of rotation of said reel immediately before its winding on said reel, irrespective to the longitudinal position of said first end of said guide element, with respect to said reel during the displacement of said first end along said direction substantially parallel to said axis of rotation of said reel.
