Abstract
In an automatic winder wherein a winding package rotates while having surface contact with a transverse drum which is positively rotated, a method and apparatus for stopping the package concurrently with stopping of the drum. The method includes a braking of the drum when brakage of yarn being wound on the package takes place and simultaneous braking of the winding package if the brakage of the yarn takes place after the winding package has reached a predetermined diameter. The structure includes drum brake structure for braking the drum, lever actuated cam structure for sensing the diameter of the winding package, and package brake structure responsive to the diameter sensing structure for stopping the winding package on sensing of yarn brakage and package diameter over a predetermined diameter.
Claims9
A method for stopping a winding package driven under contact with the surface of a driven drum in an automatic winder comprising the steps of stopping the drum, sensing whether the diameter of the winding package is at or above a predetermined diameter and separately stopping the winding package when it is sensed that the diameter of the winding package is at or greater than the predetermined diameter.
An apparatus for stopping a winding package driven under contact with the surface of a driven drum in an automatic winder comprising a brake device operably associated with the drum for stopping the drum, a sensing device operably associated with the winding package for detecting a winding package diameter equal to or greater than a predetermined diameter and a brake device operably associated with the winding package and sensing device for separately stopping the winding package only when the diameter of the winding package is at or greater than a predetermined diameter in response to the sensing device.
