For designers and operators of winding and spooling equipment, Uhing “rolling ring” traverse winding drives now feature a mechanical pitch adjustment lever. The lever is standard on all Uhing model RG traverse drives and enables a ten-to-one (10:1) pitch turndown makes it possible to spool materials of varying diameters/widths using a single traverse winder. Pitch is adjusted without changing gears or adjusting other controls. Users move the pitch selector lever which follows along a notched scale. Each notch on the scale is a discrete pitch setting. From notch to notch pitch changes by a factor of 0.01 on Uhing models RG15 through RG40, and by 0.02 on models RG50 through RG80.
If more precise pitch adjustment is required, a worm gear and threaded rod design bypasses the notched-scale settings. Users turn a control knob on the end of the threaded rod which permits fine tuning of linear pitch on-the-fly without stopping the drive system. Once pitch is set on a Uhing drive, it remains constant regardless of the drive motor speed or other control settings.
The Uhing pitch adjustment lever eliminates the need for gear reducing devices and minimizes electronic control requirements. Winding machine design, set-up and operation are thereby simplified. Both the notched scale and worm gear options for pitch adjustment are available on all sixteen sizes of Uhing model RG linear drives. Besides linear pitch, travel direction of the drive nut is also mechanically controlled independently of the motor and other controls.
