Martin Automatic refreshes it range of rewinders

Among its roll change automation equipment, Martin Automatic offers several lines of automatic transfer rewinders for continuous production in the label, flexible packaging and folding carton markets.

The newest model in the LRD line of rewinders for paper, film, labelstock and light paperboard has expanded diagnostics, and a new touch screen control that includes recipe functions, so that operators can store and recall the winding parameters of repeat jobs quickly and easily. The optional inline slitter package is now enhanced to offer lateral adjustment of the slitter and anvil roller assembly for quicker set-up, fine-tuning and changeover between jobs. The LRD offloads finished rolls automatically via one of several standard doffing ramp designs, without the need of a cart, or with an articulating arm that delivers through the side of the unit.

The STR is a compact two-spindle automatic transfer rewinder for film, paper and label stock, and is available with a servo drive option. The servo model delivers increased capabilities for specialised narrow-web applications requiring very low winding tensions and expanded taper tension control.

The LRH delivers non-stop rewinding and automatic roll discharge for mid-width presses running paper, film and paperboard. Markets include flexible packaging, folding carton, lottery printing and disposable cups. LRH versions include an 850mm (33in) wide multi-substrate model for paper, film and paperboard; and an 1170mm (46in) wide model for multi-ribbon paperboard winding.
Martin Automatic also produces non-stop rewinders for wider widths and speeds up to 914 M/min (3000 fpm), including the shafted RMAP and shaftless TR models, as well as an extensive line of automatic splicing unwinds, web transport and tension control.
