Anti-wrap device for rotating shaft.

摘要

A device that prevents wrapping of long strands of fibrous material around an exposed rotating shaft (5) has a stationary flange (10) fixed to the chassis (2) or bearing housing (6) for the shaft (5) and a rotating flange (11) fixed to the shaft (5). The flanges (10,11) are positioned to pass one another during each revolution of the shaft (5). When the flanges (10;11) are nearest to one another, a loop of vegetation forms tightly around the flanges (10,11). Continued rotation of the shaft (5) then stretches and tears the loop apart. This loop forming and tearing is repeated for each revolution of the shaft (5) to effectively prevent fibrous material from wrapping around the shaft (5).
