Overview: The document discusses the DSA Shaftless Infeed system, emphasizing its role in maintaining precise tension control for commercial and 4-color newspaper printing. This system enhances productivity by ensuring stable web tension across a wide range of operations.

Specifications: The DSA Shaftless Infeed offers web tensions up to four times more stable than traditional designs, with a stability of ± 0.5 daN (1.1 lbs). It features high dynamic servo regulation, low inertia mechanical elements, a dancer roller, and a nipping roller. The system supports web tensions from 5 daN (11 lbs) to 130 daN (290 lbs) or 180 daN (400 lbs), depending on the model.

Features: Key features include a compact free-standing unit, closed-loop regulation with a DC drive motor, PLC control, digital display of web tension, and independent electric drive. It can be retrofitted to many presses and is fully assembled, pre-wired, and tested for easy installation. Additional features include a chain web-up assist with manual crank, twin web configuration, symmetric arrangement, motorized webbing up, web tension sensors, and integrated web guides.

Performance Benefits: The system minimizes paper waste during make-ready and production, offers exceptional stability (< ± 0.5 daN), and provides precise web tension control. It allows for fast and accurate corrections at speeds up to 915 m/min (3000 fpm) and features simple operation and maintenance.

Technical Specifications: The maximum speed is 15 m/s (3000 fpm), with web widths ranging from 1020 mm to 2040 mm (40" to 80"). The system ensures web tension stability of < ± 0.5 daN (< ± 1.1 lb) and a minimum tension of 5 daN (11 lbs). Models include the DSA 130 with a maximum tension of 130 daN (290 lbs) and the DSA 180 with a maximum tension of 180 daN (400 lbs). Integrated infeeds are available for web widths up to 1270 mm (50") on DLP 2-50 pasters.
