Abstract (en)
A bobbin-changing device (4) for a winding machine comprising a first feed path (12) of bobbins (7) comprising a tube (6) on which a yarn (5) is wound, said first feed path (12) being shaped to feed a plurality of bobbins (7) to be unraveled, an input disc (20), arranged so as to intercept the first feed path (12), rotatable around a first axis of rotation (X1), and comprising a first side wall (22) shaped with first curvilinear sections (23) provided with at least a first recess or radial seat (24), facing said first axis of rotation (X1), configured to selectively retain and release said at least one bobbin-holder (7) plate (8), an output disc (30), rotatable about a second axis of rotation (X2), comprising a second side wall (32) shaped with second curvilinear sections (33) provided with at least one second recess or radial seat (34), with convexity facing said second axis of rotation (X2), configured to retain a bobbin (7) received from the input disc (20) and release the tube (6) of said bobbin (7) after it has been unraveled, a second release path (40) of bobbin (7) tubes (6) shaped and positioned so as to receive said tubes (6) released from the output disc (30),- a branch (50) connecting the first feed path (12) and the second release path (40) and intercepting the input disc (20) and the output disc (30) to allow the exchange of bobbins (7) between the input disc (20) and the output disc (30).
