VDI 101-248 DOUBLE TIRE REEL SPOOL STARTER A reel bar drive for use with a web winding system, such as the dry end of a paper making machine has a pair of driving wheels adapted to make driving contact with a peripheral end portion of a reel bar. The driving wheels are mounted on a pivotal platform located to one side of the winder. The platform is pivotable in an arcuate path having a component direction relative to the axis of the reel bar so as to move the driving wheels into driving relation with a peripheral end portion of the reel bar. Owing to the pivotal mounting arrangement, the position of the driving wheels are adjustable to compensate for changes in the reel bar position as it commences its web reeling operation. The reel bar drive may utilize its self weight to enhance frictional contact between the drive wheels and the reel bar. Upon withdrawal of the supporting platform, the drive wheels are displaced completely clear of the winding system. Thus, the reel bar drive is suitable for use with a reel bar auto-loading system and facilitates safe maintenance of component parts of the reel bar drive.
