STR Automatic Turret Rewind

Compact non-stop turret rewinder for label converting and narrow web applications, featuring integrated web guide and lay-on roller for high quality rolls.

• The Martin STR Automatic Turret Rewind is ideal for non-stop roll changing in narrow web printing and converting processes.
• The STR is a compact unit for continuous production of rolls. When the specified footage has been rewound, the completed roll is stopped, and a festoon accumulates the printed web at full press speed. The turret indexes, presenting the finished roll for removal, and the web is automatically transferred to an empty core.
• The transfer mechanism is designed to begin new rolls without web foldback at the core, eliminating a source of wrinkling and material waste. The STR also features a lay-on roller and integrated web guide for greater winding control and higher quality rolls.
• Simple transfer preparation and few operator controls are typical of Martin’s design philosophy. The standard DC drive package and PLC-based control system guarantee a high level of reliability with minimal maintenance.
• Standard STR models are available for widths to 13 inches (330 mm) and roll diameters to 24 inches (610 mm). For nonstop roll-to-roll processes, the STR is offered with the STS automatic Splicing Unwind. Speak with your Martin representative for more details.
