Assembly for handling reel spools and a reel-up unwinding arrangement for a fiber web machine

A reel-up—unwinding arrangement for a fiber web machine, comprising a reel-up station at a first end of the arrangement, configured to produce parent rolls from a running web on a reel spool supported from bearing housing at reel spool ends, and an unwinding station at a second end of the arrangement, configured to controllably unwind web from the parent rolls produced in the reel-up station, and an assembly for handling reel spools configured to operate between the reel-up station and the unwinding station, the assembly comprising

• linear support rails, having a first end and a second end, arranged parallel to each other,
• a reel spool cart comprising a transverse bridge, arranged on the support rails,
• the support rails being arranged at a first distance from each other, the first distance being greater than axial length of the reel spool,
• the cart being provided with a hoisting device,
• wherein
• the hoisting device is configured to hoist the highest point of the reel spool vertically from beneath of at least one of the support rails to at least partly above the at least one of the support rails and in that
• the reel spool cart is provided with lay-down support for the reel spool at its both ends wherein the lay-down support is provided with a drive by means of which the lay-down support is configured to be moved under a bearing housing of the reel spool, after the reel spool has been lifted to a vertical position above the lay-down support.
