The invention relates to an electric machine for applying a spiral-shaped protection tube on some premounted wires and/or cables. According to the invention, the machine comprises an electric motor (1), a housing (17), a speed variator (2), a driving valve (22), a kinematic link comprising two bevel toothed gears (3 and 4), a pulley wheel (5), a toothed belt (6), two pulley wheels (7 and 8) and two driving drums ( 9 and 10), fastened on the housing (17), contacting a protection spiral (15), spirally located in a system comprising a claw (16) sliding on the housing (17), four drums (11, 12, 13 and 14) fixed on the claw (16) which, together with two springs (23 and 24), carry out the pressing of the protection spiral (15) on the driving drums ( 9 and 10), thereby winding said spiral on wires and/or cables (32) mounted in a sub-assembly comprising a claw (16), a spacer head (25), an ear (19), a preformed leaf-spring (20) which pushes the fastening ear (19) towards the claw (16) and another preformed leaf-spring (21) forcing the wires and/or cables (32) to reach a position which will facilitate the application of the protection spiral (15). |
