Abstract:
A bobbin winding machine comprising a plurality of aligned winding stations and a transport system for conveying spinning bobbins supported in upright disposition on transport elements to and from the winding stations, the bobbin transport system having a feed track extending along one side of the winding stations for conveying transport elements each carrying a spinning bobbin to be unwound, a removal track extending along the opposite side of the winding stations for conveying transport elements each carrying an unwound spinning bobbin, and a plurality of transverse transport tracks each extending from the feed track to the removal track through a respective winding station, each transverse transport track having a positioning element selectively movable into and out of the associated transverse transport track between a first position operative during unwinding operation of the associated winding station wherein the positioning element is disposed within the transverse transport track for engaging and positioning a transport element at an unwinding position at the associated winding station and a second position operative after completion of an unwinding operation of the associated winding station wherein the positioning element is disposed outside the transverse transport track for releasing the transport element from the unwinding position at the associated winding station, and each positioning element having a device movable therewith between the first and second positions into and out of the associated transverse transport track, the device being configured to occupy a sufficient extent of the associated transport track between the unwinding position and the removal track for limiting the capacity of the transverse transport track to be occupied fully by at least one transport element between the device and the removal track during the unwinding operation.
