Safety chucks By providing a way to transmit torque to a sheet or film roll that is either winding or unwinding, these products make possible quick changes at the end of a production run. Available through Goldenrod, a partner of Svecom P.E., Montecchio Maggiore, Italy, they provide for concentricity to the centerline of the roll shaft, reducing vibration and wear.
What’s new? Goldenrod’s Model 928, which is designed to replace conventional safety chucks. Compared with conventional chucks, which feature metal journals riding upon metal sockets, the Model 928 safety chuck incorporates a cup that houses bearings that support the rotating shaft located on each of the support journals. Both machine makers and machine users can install the Model 928, either to new rewinders or as a retrofit.
Benefits Smooth operation, operator safety and the elimination of the potential for damage caused by metal-on-metal wear, which can lead to the need for constant maintenance. The Model 928’s bearings do not rotate, so, unlike conventional safety chucks, the operator is not exposed to any rotating parts. A radiused flat journal end delivers torque for movement and braking. Once the shaft is rotating, the chucks automatically close. An operator can open the chuck only when it is in the 12 o’clock position once he or she retracts the redundant safety lock and opens the chuck’s outer ring. Overall, safety chucks lower downtime, making operations more cost-efficient.
