Eliminating overtightened caps means less maintainence and fewer frustrated customers. One of the last steps in any bottling process is putting on the cap, a task usually done by electromechanical devices called headsets. One problem with traditional headsets, however, is that they apply the torque that attaches the cap in one mighty surge. This often results in overtightened caps. And bottling companies trying to cut back on material costs by using smaller caps give customers little to hold on to when untwisting a cap. So if one of these smaller caps is overtightened, a large segment of the population will have difficulty getting the bottle open. The torque surge is also hard on equipment, with headsets needing to be rebuilt or replaced every three to four months. Other components suf fer as well. For example, retention knives — the mechanisms that hold bottles in place while being capped — wear out quickly. , a company based in South Beloit, Ill., under ) adapted the technology used in its magnetic clutches and brakes. It applies torque smoothly and consistently. This eliminates overtightening and reduces the variation in the amount of torque needed to unscrew a cap. The headsets have been in use at a Bottling Plant in Detroit for over a year. In that time, they haven't had to rebuild a headset or replace a retention knife. And removal torque has stayed within 1 lb of the target value. The steel headsets come with a quad seal and drain holes. At the Pepsi plant, this translates into corrosion-free headsets. "Our previous heads would rust after only 10 weeks," says Dwayne Johnson, a Pepsi production technician. The steel also lets the headsets resist ozone, a gas used in bottling water. The devices have a visual scale on the side for setting torque, making
Products & Services
Headsets are designed to hold earphones to a user’s head for radio or telephone communications. They include transducers and a transmitter, and are designed to receive audible signals from a source such as a portable media player or audio amplifier. Often, headsets are bundled with microphones for two-way communication. The main benefit of headsets is that they let users listen privately, and make it easier to hear in noisy environments.
Capping machines are used to secure caps onto bottles and drums.
Caps, Grips, and Closures
Caps, grips and closures are protective devices for the ends of a shaft, tube, pipe, fitting, connector, screw, bar, or other shape. They can also be used to provide a hand grip or hanger tip.
Audio headphones are small speakers worn over the ears to isolate sounds for the listener.
