Abstract
Device to automatically attach a first bobbin-bearing mandrel (11) to a second mandrel (15) of a machine, wherein the first mandrel (11) and the second mandrel (15) have substantially the same outer diameter and are suitable to be inserted selectively into the central hole of the bobbin (13), coupling means (40, 50) being provided on the first mandrel (11) to selectively couple with the second mandrel (15), to allow the coaxial transfer of the bobbin (13) from one to the other of said mandrels (11 and 15).
Claims17
A device for bearing a bobbin (13) comprising a support element (16) wherein a mandrel (11) is cantilevered mounted, said mandrel (11) having at least a substantially cylindrical section able to cooperate with a corresponding central hole of said bobbin (13), characterised in that said mandrel (11) is provided with first coupling means (40, 50) able to cooperate with a corresponding support member (15) on which said bobbin (13) is able to be mounted, for allowing and helping the axial shifting of said bobbin (13) from said mandrel (11) to said support member (15).
