ABSTRACT:
In a machine for winding yarn to form a package, a winding drum supported in engagement with the package for traversing yarn from end-to-end as it is wound, a drum wheel for effecting rotation of the drum, a traction roll and brake shoe supported for movement relative to the drum wheel, on the one hand to engage the traction roll with the drum wheel and simultaneously disengage the brake shoe therefrom and, on the other hand, to disengage the traction roll from the drum wheel and engage the brake shoe therewith, a drive shaft for driving the traction wheel constantly, and mechanism for intermittently oscillating the traction roll and brake shoe relative to the drum wheel while maintaining engagement of the traction roll in driving engagement with the means for driving the traction roll. A pivotally supported package arm supports the package in engagement with the winding drum, a roller is supported in engagement with the brake shoe by one arm of the bell crank and a spring stretched in tension with one end connected to the support arm and the other to the other arm of the bell crank applies pressure to the package which decreases with the increase in size of the package and pressure to the brake which increases with the size of the package.
