Abstract:
A device for bearing a bobbin and automatically and axially coupling a first bobbin bearing mandrel to a second bobbin bearing mandrel wherein said first bobbin bearing mandrel is cantilevered mounted on a support element, wherein both said first and second mandrels have at least a substantially cylindrical section able to cooperate with a corresponding central hole of a bobbin, wherein said substantially cylindrical sections have substantially the same external diameter, the device comprising a first coupling member provided on one of said mandrels, a second coupling member provided on the other of said mandrels, said second coupling member able to cooperate with said first coupling member for coupling together said first and second coupling members for allowing and helping the axial shifting of said bobbin from one of said mandrels to the other of said mandrels, wherein said first coupling member comprises an abutment element having a release position and an attachment position, said abutment element in the attachment position extending further outwardly from a longitudinal axis of said one of said mandrels than said abutment element in the release position, and an actuator for switching said abutment element between said attachment and release positions, and wherein said second coupling member comprises an inwardly facing shoulder against which said abutment element is pressed in the attachment position to attach said first and second mandrels together.
