Drive system for a yarn eye or yarn winder

摘要

A machine wherein a yarn is fed at a constant delivery speed through a yarn eye to a yarn package rotated at a constant peripheral speed has a drive system connected to the yarn eye to reciprocate it at an irregular rate to wind the yarn irregularly on the package. This yarn eye is connected through a cam to a sun gear in mesh with a planet gear carried on a planet carrier and rotationally coupled to a starwheel. A control wheel and the planet carrier are continuously rotated at different speeds. This control wheel has formations which prevent the starwheel from rotating during part of each orbit of the starwheel about the machine axis and which rotate the starwheel at a fixed speed during another part of each orbit so that the displacement speeds of the cam and, hence, of the yarn eye alternate between two separate rates for most effective irregular winding.
