Abstract:
A reeling shaft transfer rail system has two parallel substantially horizontal or slightly sloped rails for supporting the ends (25) of a reeling shaft (20). Hoses are arranged on each of the transfer rails (15) and filled or drained to move and hold the reeling shaft (20). In a method of transferring reeling shafts on transfer rails, the reeling shafts (20) are transferred on two parallel, substantially horizontal or slightly downstream of a main transfer direction inclined transfer rails (15) for supporting each of the supporting ends (25) of a reeling shaft (20). The reeling shafts (20) are transferred or positioned in the reeling shaft transfer rail system (10) by pressurizing hoses (17) arranged on each of the transfer rails. The hoses are arranged so fluid added to or withdrawn from the hoses pushes or holds the reeling shaft (20) on the transfer rails (15).
