PCT No. PCT/EP90/01430 Sec. 371 Date Dec. 4, 1992 Sec. 102(e) Date Dec. 4, 1992 PCT Filed Aug. 28, 1990 PCT Pub. No. WO91/18813 PCT Pub. Date Dec. 12, 1991.A drive arrangement for apparatus for reeling a traveling web into a reel includes a pair of spaced, parallel guides for supporting a tube on which the web is to be wound. The guides are mounted on pivotable arms and the tubes are rotatably supported in a carriage at either end, which carriages are adapted to traverse the guides as the diameter of the wound web reel grows. A looped, motor-driven belt is disposed over a drive wheel on the carriage to provide torque to the tube continuously from when the tube is initially nipped with a backing roll to when the wound web reel is finished. The carriages are moved along the guides by a motor driven traction mechanism, such as a looped chain which is attached to the carriages. |
