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 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 has an attachment position in which said first coupling member is connected to said second coupling member, and has a release position in which said first and second coupling members are disconnected, and at least one lever provided in a longitudinal slit in said one mandrel for switching said first coupling member between said attachment and release positions, said at least one lever having a first position protruding from said one mandrel for switching said first coupling member to the release position, and a second position within the slit for switching said first coupling member to said attachment position, wherein said at least one lever is forced into said second position within said slit when said bobbin is provided on said one mandrel.
