The invention relates to an arrangement for a belt drive device, which comprises two continuous drive belts, which arc arranged to be operated by means of drive rollers (), and which are arranged to travel around stretching rollers as continuous loops spaced apart, and which are arranged to be pressed by means of press rolls against the opposite surfaces of a cable or the like () to be drawn. In order to provide a simple structure, the drive rollers () are arranged to be rotated by a single power source by driving two planetary gears () connected in parallel and provided with angular front transmission. The rotary motion generated by the power source is arranged to be transmitted in the same direction to primary axles () of both planetary gears () provided with angular front transmission in order to rotate secondary axles () and the drive rollers () connected thereto in opposite directions.

Arrangement for belt drive device

An arrangement for handling cylindrical bodies provided with central holes, the apparatus comprising gripping arms provided with gripping pins, second means arranged to move the gripping arms to obtain a forward movement, third means arranged to wind the gripping arms clockwise and counterclockwise, and fourth means arranged to move the gripping arms towards each other such that the gripping pins are self-centeringly brought into alignment with the central holes of the cylindrical body and to make a reverse movement of release. To provide an arrangement operating with high speed, the second means by which the forward movement of the gripping arms is obtained and/or the third means by which the winding movement of the gripping arms is obtained are formed as an elastic structure in a predetermined area such that the gripping arms are capable of adapting, during the grip movement and movement of release, to the displacements of position within this area, the displacements being determined by the position of the body or the position of the stand carrying the body.
