The twin Martin machines at the family-owned converter, based in Bornem, Belgium, between Antwerp and Brussels, include several customized options. In a typical Martin butt-splicer configuration, the festoon (accumulator) that supplies web to the press during the splice cycle, is mounted at the end of the unwind section.
Seeking to minimize the use of production floorspace, Desmedt asked Martin’s designers to come up with a solution that offered a smaller footprint. The ingenious result was to stack the festoon on top of the unwind, with the rollers at waist-level. “Not only did Martin shorten our line length, but it is easier for the operator to access the web, and the equipment is at a convenient height for cleaning. Keeping the operator happy is an important element in our Lean Manufacturing program, of which the two Martin units are key elements,” he adds.
The two MBSF (‘F’ for film) splicers are also fitted with Martin’s latest development, a reverse-side-tape laser assist device, which accurately aligns the tape with the web edge and eliminates any hand/eye coordination errors. According to Desmedt, it is particularly effective if the edges of the matrix are reduced to save waste, and to date has worked well with no missed splices in commercial production since the training period at installation. “The Martins are proof that the basic laws of physics work well, without the need for complex technology. Our operators tell us they would not want to be without them, and as proof of the equipment’s intrinsic reliability, the splicers are two machines that are never discussed in production meetings,” he says.
Desmedt is proud of its Lean Manufacturing program, which in addition to the Martin Automatic equipment includes a waste-removal system and turret rewinders, all designed to allow non-stop production. In addition, the company has encouraged its workforce to become involved in the program, and created an atmosphere in which everyone is invited to suggest ways and means of improving efficiency, however minor. Köhler explains, "If we can each find a way of saving a few minutes or a few Euros, then the cumulative effect can transform our productivity. It’s finding the perfect balance between human and machine capability that enriches a business, so we all must play our part.”
Originally established in Brussels in 1889, Desmedt Labels was one of the first in continental Europe to achieve HD-Flexo status, and is proud of its reputation for quality labels and printed packaging that includes: promotional labels, coupons, dry peel labels, tags, duo and trio labels, and on the security side, tamper-evident and RFID labels. The company has both flexo and digital print capability, is accredited with EN ISO 9001-2008, and is fully FSC compliant.
Concluding, Henri Köhler says, “Although our experience of working with Martin Automatic has been relatively short, it has proved invaluable to our operation here. They listen closely to what is asked of them, are happy to make even the smallest of changes, and have thus become one of our preferred suppliers.”
