Martin Automatic has introduced the MDR (magnetic driven roller) system, an advanced solution for handling light webs at lower tension levels and higher operating speeds. The new MDR technology can be applied to both web transport systems and to Martin’s line of high-performance unwinds.

“The continued emphasis in converting and printing today is to increase throughput by increasing process speeds,” says Mike O’Hea, product manager for the MDR project. “At the same time, material basis weights and calipers continue to decrease. These lighter material structures can only run successfully at lower web tension levels, restricting the ability to reach higher speeds.”

“Martin manufactures zero-speed splicers for nonwovens and other extensible webs. For good reasons, zero-speed splicing of nonwovens (using a storage festoon or accumulator to pay out web while the splice is made) is the preferred and often necessary method of automatic roll changing. But these opposing trends of lower tensions and higher speeds present real challenges for splicing and web handling. MDR is an effective new tool to overcome these challenges.”
