Winding Technology - QFP Systems
QFP Systems - "Quality, Functionality & Performance"
QFP winding and unwind systems are built for efficiency and profitability for rolls 50 inches in diameter and below. These pre-engineered systems are delivered wired, piped, and tested for more efficient start-ups and to minimize costs. Shafted or shaftless versions are available to accommodate a variety of applications including solution coating, extrusion coating, flat and embossed films, non wovens, CPP, and BOPP films. The QFP is available in three sizes: 30-inch and 42-inch (762mm and 1,066mm) diameter models for rolls up to 3,000 pounds or 1,360 kg (Model 20); and a 50-inch (1,270mm) diameter model for rolls up to 5,000 pounds or 2,268 kg (Model 30). Pre-engineered models are available in widths up to 120 inches (3,048mm). All models have a maximum speed of 2,000 fpm (610 mpm).
Highlights of fixed and adjustable arm QFP:
- Pre-engineered mechanical drives with drive motors mounted off the turret.
- Max tension of 200 pounds or 91 kg (Model 20) and 300 pounds or 136 kg (Model 30 and Heavy 20).
- Model 20 indexers of 1, 2 and 8 rpm; Model 30 indexers of 1 and 2 rpm.
- Model 20 available with pivot-out shaft system.
- Model 20 and 30 available with latching both sides of the machine to aid in easy roll removal.
- Integrated controls using Allen Bradley PanelView operator interface and Control Logix plc platform. Other systems available as options.
