ABSTRACT:
This invention presents both a method and device capable of accurately measuring fixed lengths of moving strand or yarn as it is pulled from an essentially continuous source of supply and wound onto a take-up reel by an appropriately powered winding mechanism. In its preferred embodiment, the invention is used to measure lengths of fiberglass strand unwound from forming packages and onto rotating bobbins carried on a twist frame. As its principal component, the invention utilizes a lightweight, low inertia measuring rim supported on a layer of pressurized gas, such as air, so that frictionless rotation of the rim about a stationary hub is thereby made possible. Moving strand is maintained in continuous contact with the rim thereby causing it to rotate. The number of rotations is counted by electrical means and multiplied by the circumference of the rim whereby the length of strand advanced over the rim and onto the rotating bobbin is calculated.
