ABSTRACT:
A rotary vacuum wicketting device has a stationary hub and a rotary hub that has a number of vacuum arms to carry plastic bags or similar workpieces from a first work station to a second work station where they are placed on a wicket. The rotary and stationary hubs are both molded of a plastic synthetic resin which has been filled with a suitable lubricating agent. The radial arms are also formed of the plastic synthetic resin and are molded to have a square cross section from the radially outward end to and including the male portion that fits into a square cross section socket in the peripheral wall of the rotating hub. The tubular arms have a removable end cap to facilitate cleaning debris that may have collected inside the arms. A removable plastic wear plate is carried on the forward-facing surface of each of the arms to absorb wear and abrasion from action of the plastic film workpieces.
