Davis-Standard‘s newest PAC 60 surface winder is capable of winding film in widths up from 80 inches (2,000 mm) to 140 inches (3,500 mm) with a single or dual winder configuration.
The winder, developed from the successful platform of the PAC 60 introduced a few years ago, uses a centre shaft support for three-inch (75 mm) cores to wind multiple slit rolls to a 30-inch (750 mm) outside diameter, while 40-inch rolls are wound on six-inch (150 mm) shafts.
This model is equipped with a motorized roll cart and shaft puller that are fully integrated into the winder’s PLC-based controller, reducing operator lifting of shafts and automating the winding process to a higher level. A hydraulic pressure control system for lay-on arms and centre assist winding motors facilitate good roll starts, which lead to high quality large rolls. For stretch film, a special lay-on roll is utilized on the surface drum in-feed to eliminate air, and improve film relaxation prior to winding.
The PAC 60 is well suited for stretch film winding or large roll mill operations where films are converted in lamination or made into bags or sacks off-line. The winder is designed with lay-on pressure control to prevent blocking at the core, and features a shaft accelerator to bring the new core to higher line speeds, and make transfers via an auto-cut traversing knife.
The PAC 60 is capable of speeds exceeding 200 meters per minute. While available in 40, 50, 60, 70, 80, and 90-inch models (1,000 to 2,300 mm), the new winder extends that range to 165 inches (4,200 mm).
