The Emba 245’s rigid construction allows for tighter print registration, fast changeovers to reduce downtime and has the room to add a fourth color. Additionally, the machine is equipped with a Valco Melton ClearVision high-resolution camera-assisted hot-melt glue application and inspection system, which monitors glue bead place- ment in real time, detects misses, skips, excess glue, or misalignment issues and triggers automated rejects.
and containerboard converting operations in California and perhaps, the Southwestern United States. Adapting size and scope of its geographic reach has its competitive advantages. For example, the efficient and profitable operation of five highly productive corrugator and sheet plants de- mands that machinery be constantly maintained, upgrad- ed, moved, replaced and purchased. Consider when Cal- Box I invested in a new J&L 190-inch Specialty Folder Gluer from Alliance four years ago; it moved the J&L 150-inch machine that was running there 40 miles east to CalBox II in Rancho Cucamonga to add capacity at that plant. The J&L 130-inch machine that was running at CalBox II was shipped to WTC in El Paso. Due to the J&L’s reliability and CalBox’s strict attention to PMs, all specialty folder gluers continue to perform at maximum efficiency and production speeds.
“The ClearVision system ensures that every box is made perfectly, the benefits of which are obvious,” says Chris Widera, adding that another “favorite” and critical part of the machine is the counter-ejector, which comes off the folding section and precisely stacks, counts, and squares bundles. No room for errors, just perfect boxes, delivered “On Time, With Quality: No Excuses,” which happens to be the title of a popular book John Widera published in 1992 that describes in great detail the importance of the phrase that nearly 35 years later still represents the foundational philosophy on the way CalBox Group operates a success- CalBox’s Emba boasts a Valco Melton ClearVision high-resolu- tion camera-assisted hot-melt glue application and inspection system, which monitors glue bead placement in real time, en- suring virtually perfect boxes.
The 190-inch J&L operating in CalBox I delivers on the flexibility, capacity and speed of the 150-inch machine but in a larger format; it converts single to double wall corru- gated, heavy weight board, litho laminated E/F flute and specialty flutes for customers representing the spectrum of segments in SoCal market. The machine’s servo drive was an important feature for the Wideras, as it was on their most recent investment: a shiny new EMBA 245 Quick Set Ultima Flexo Folder Gluer, a 3-color revenue-generating production tool that was introduced to the machine family at CalBox I. The decision to add the Emba was made large- ly because of the outstanding performance of the same machine running in CalBox II. The Trend To Servo “Our new Emba 245 is a servo-driven machine. The old- er machine it replaced was gear-driven,” says Chris Wide- ra. “The trend with our new flexo folder gluers is they’re all servo machines. Why? The gear-driven machines were a little ‘sloppier’ and required more maintenance. Servo ma- chines are easier to maintain and they’re also a lot quieter than a gear-driven machines, which both our operators and fellow employees appreciate.” 28 March 30, 2026 The 190-inch J&L operating in CalBox I delivers on the flexibil- ity, capacity and speed of the 150-inch machine but in a larger format.

His newest book, “Entre- preneurs Succeeding in an AI-Digital Crisis,” is expected soon). The decision to install an EMBA 245 Quick Set Ultima 3-Color Flexo Folder Gluer at CalBox I was made largely because of the outstanding performance of the same machine running in CalBox II.
