You should be able to find several indispensable facts about Plastic Film Winders in the following paragraphs. If there’s at least one fact you didn’t know before, imagine the difference it might make.
Now that we’ve covered those aspects of Plastic Film Winders , let’s turn to some of the other factors that need to be considered.
Winders for both cast and blown film have changed greatly over the past three to five years. They now wind larger diameters and better-quality rolls out of thinner, stretch ier films at higher speed and lower tension. This is the result of not one development but many. Starting in the mid 1990s, load-cell tension controls, tapered-tension capability, and AC flux-vector drives began replacing dancer tension control and DC drives.
Macro Engineering supplied its first flux-vector drive in 1990 for an experimental extrusion coating line that wound coated paper at 3500 ft/min. (Paper can wind at 8000 ft/min and nonwovens at 4500 ft/min because they’re non-stretchy, porous, and don’t trap air.)
The first plastic film winder with an AC flux-vector drive controlled by a touchscreen PLC was Battenfeld Gloucester’s Model 1011 small turret center winder designed for three-layer blown film in 1991. Black Clawson and Reinhold both delivered their first AC vector drives and PLC controls on plastic film winders in 1996. By five years ago, most winder makers were building some models with AC drives and PLCs. By two years ago, virtually all makes and all models had switched to these technologies.
