Back to Basics

In addition to its release of new shaft technology, Convertech has introduced pneumatic step chucks. The new technology frees operators to run two different core diameters without any adapters or changing of the chucks. The pneumatic step chucks come in sizes that range from 70 mm to 12˝.

Double E. Co.'s DF-2000® torque-activated core chuck has new slide-on adapters, making changeover from one core size to another quick and easy. The DF-2000 uses rollers which travel up and down bi-directional ramps for expansion and retraction of its jaws. The rolling mechanism decreases friction and eliminates the need for lubrication. The DF-2000 also features smooth gripping jaws, and is available in sizes from 2.75˝ and up, as well as in single, quick-disconnect, step, and through-shaft models.
