Abstract

A combined device for bending and cutting ribbon-shaped elements is described, comprising first guiding and supporting means (1, 101) adapted to allow positioning a ribbon-shaped element (T, T1), second guiding and supporting means (3, 103) adapted to prevent the rotation of the ribbon-shaped element (T, T1) with respect to an axis belonging to a plane on which the ribbon-shaped element (T, T1) rests, first translating means (41, 1041) and rotation means (4, 104) adapted to move a tool (5, 105) with respect to the second guiding and supporting means (3, 103); the second guiding and supporting means (3, 103) comprise a portion of bending profile (8, 108) adapted to bend the ribbon-shaped element (T, T1) and a portion of cutting profile (9, 109) adapted to cut the ribbon-shaped element (T, T1). A method is further described for bending and cutting ribbon-shaped elements performed through such device.

Abstract

A combined device for bending and cutting ribbon-shaped elements is described, comprising first guiding and supporting means (1, 101) adapted to allow positioning a ribbon-shaped element (T, Tl), second guiding and supporting means (3, 103) adapted to prevent the rotation of the ribbon- shaped element (T, Tl) with respect to an axis belonging to a plane on which the ribbon-shaped element (T, Tl) rests, first translating means (41, 1041) and rotation means (4, 104) adapted to move a tool (5, 105) with respect to the second guiding and supporting means (3, 103); the second guiding and supporting means (3, 103) comprise a portion of bending profile (8, 108) adapted to bend theribbon-shaped element (T, Tl) and a portion of cutting profile (9, 109) adapted to cut the ribbon-shaped element (T, Tl). A method is further described for bending and cutting ribbon-shaped elements performed through such device.

Abstract

A machine (1) for working a ribbon-shaped element (T1, T2′, T2″) is described, comprising at least one cutting station (2) crossed by the ribbon-shaped element (T1, T2′, T2″), guiding means (3, 4) adapted to position and drag the ribbon-shaped element (T1, T2′, T2″) onto at least one fixed plane (PI) of the cutting station (2) keeping an edge of the ribbon-shaped element (T1, T2′, T2″) tangent to a fixed point (A1) of the fixed plane (Pi); at least one of the guiding means (3, 4) rests onto an arm (31) free of rotating with respect to a fixed axis (33); the fixed axis (33) is at the same distance with respect to the cutting station (2) and the at least one of the guiding means (3, 4).
