Five-minute changeover for cartoner at wafer maker

Swiss wafer manufacturer Kägi Söhne swaps outdated equipment for a top-load car toner that offers significant flexibility and quick changeover for its range of packaging sizes and styles.

Since 1958, Kägi Söhne AG of Toggenburg, Switzerland, has been producing one of the best-known Swiss wafer specialties, Kägi fret. Founded 75 years ago by Otto Kägi, the company began as a manufacturer of a variety of biscuit products and in 1958 introduced the milk chocolate-coated wafer that has now become a Swiss institution. Today Kägi employs more than 80 associates and produces more than 3,000 tons of wafers and biscuits annually. Over the years, the company has expanded into new markets too, with exports now accounting for 40% of its overall production.

Recently the company found that its existing carton-packing equipment could no longer meet the growing productivity requirements of its Kägi fret product. Explains Hanspeter Scherrer, Production Manager at Kägi, “The previous line used outdated technology, and it is vital for our production that we have a line that is available at all times. This is why we decided to renew the top-loading process.

“Our main objectives for the new line were higher efficiency and plant availability, along with the fast and easy format changes required to maintain increasing output levels.”

Having a long and successful history with Bosch Packaging Systems AG, a company of Bosch Packaging Technology, Kagi selected the supplier’s Sigpack TTM top-load cartoner, which can pack products into virtually every common top-load carton style at speeds to 150 cartons/min.

“Ultimately it was the [equipment and service] package as a whole that decided it for us,” says Scherrer. “The physical proximity of Bosch in Beringin, Switzerland, and the company’s reliability and accessibility also contributed to our decision in favor of Bosch for this project. With the Sigpack TTM, we have acquired a powerful platform with state-of-the-art technology that also gives us the potential of being equipped for future challenges.

“The new line also brought us a number of technical advantages designed for a high and consistent output, including 100-percent carton control as well as high Overall Equipment Efficiency.”
