Winding frame

A winding frame swingably mounted on a machine frame and operable to support a rotatably driveable winding core for the winding of a filament thereon, the winding frame comprising:

• a linkage for mounting the winding frame to the machine frame for swinging movement of the winding frame relative to the machine frame in a first swinging direction and a second swinging direction opposite to the first swinging direction;
• and
• a damping apparatus for opposing unscheduled swing movements of the winding frame during regular winding of a filament onto the winding core, the damping apparatus having:
• a housing pivotally mounted on the machine frame for pivoting about a housing mounting axis;
• a guide rod having one end pivotally secured to the winding frame, the guide rod extending through the housing in a disposition permitting movement of the guide rod relative to the housing,
• a piston having a braking surface thereon, the piston being disposed in the housing;
• a cylinder disposed in the housing, the piston being movably mounted in the cylinder for adjustable movement of the piston in a direction perpendicular to the axis of the guide rod so as to selectively bring the braking surface into contact with the guide rod to thereby resist the movement of the guide rod relative to the housing and out of contact with the guide rod to thereby permit movement of the guide rod relative to the housing, and the guide rod, the housing, the winding frame, and the machine frame being arranged relative to one another such that, during the swinging movement of the winding frame relative to the machine frame, the spacing of the housing mounting axis and the machine frame from one another does not vary while the spacing of the one end of the guide rod pivotally secured to the winding frame and the housing mounting axis from one another varies and, during the swinging movement of the winding frame relative to the machine frame, the housing guides the guide rod therethrough.
