Zalkin bloc rotary roll-on + screw-on capping systems use Zalkin’s proven capping head technology to apply Torque-on Pilfer Proof (TOPP) aluminum closures to glass bottles at speeds up to 900 cpm (54,000 cph).
TOPP closures, also referred to as Torque-on Pilfer-Proof closures, were specifically designed for the wine and spirits industries. They feature a plastic, screw-on fitment inside an aluminum closure. This style of cap provides twist-off and twist-on reclose convenience for the consumer as well as the security provided by a roll-on tamper evident or pilfer proof band.
Dual function screw-on + roll-on heads apply TOPP aluminum wine bottle closures in a single operation. They are a high-performance solution that combines Zalkin’s constant torque screw-on capping technology with our roll-on capping technology for aluminum closures.
With rotary roll-on + screw-on technology, TOPP aluminum caps are transported single-file via a chute and fed individually into a transfer starwheel. The capping heads pick-up the closure and align it with the container. The caps are then sealed to the container by the rotating roll-on capping heads which seal the closures on the container using constant magnetic torque control or servo drives. Finally, the tamper evident band is formed by pilfer-proof rollers with precisely controlled side pressure.
