Zalkin rotary screw-on cappers for bloc systems use Zalkin’s proven pick and place technology to apply plastic screw caps (including tethered) to containers at speeds up to 1,500 cpm (90,000 cph).
With pick and place technology, caps are transported single-file via a chute and fed individually into a transfer starwheel with pockets or pegs. The caps are then secured by capping head chucks which then apply the closures using precisely controlled top pressure and screw-on torque.
Virtually every filler manufacturer including Krones, KHS, Federal, Pacific, Serac, U.S. Bottlers, Elmar, Bertalosso, MBF, TechLong, BevCorp, Sacmi, Weightpack, Ocme, MRM Elgin, PackR, Fogg and Sidel all routinely incorporate Zalkin systems in their bloc fillers.
The high-performance heart of Zalkin screw-on cappers are the capping heads that deliver reliable, repeatable and accurate closure application.
Zalkin application engineers work closely with customers to select, design and configure the capping head technology that is ideally suited to each application and production environment.
