ABSTRACT:
A device comprising a casing which bears two distinct hinged (articulated) systems, of which one is activated by jacks and includes four arms of which two are hinged together at one of their ends while another is hinged on the casing and on the free end of the arm, and the arm is hinged on the casing and at the middle of the arm that bears a roller to disengage the cop from the drive shaft.
The other system comprises two parallel arms hinged on an intermediate plate, two parallel arms hinged on the plate and on a support of the re-attachment head connected to a system of suction by means of a conduit and including two motors to drive in rotation a roller controlling the cop and to make its front part rotate by 180.degree. in respect of its rear part.
In the re-attachment position the roller is employed to rotate a roller by friction located at the outlet of the turbine.
