Two Drum Surface Winders

About Our Two Drum Surface Winders:

Surface winders have been in use for over 100 years and were the orginal style of production machine.  We have continued that legacy with state-of-the-art Two Drum Surface winders.  They are ideal for wide width, heavy weight, high speed winding of paper, textiles, non-wovens and more.

TD4300

 

About The TD4300 Simplex: 

The TD4300 is a robust, compact, machine capable of slitting most papers, boards and laminates.  It bridges the gap for applications too large for center-surface machines and applications that don’t require heavier duty two drums.

FAQ’s

Frequently Asked Questions About Two-Drum Surface Slitter Rewinders

What is a two drum surface slitter rewinder and what makes it different from other types?

It’s a machine where rolls are wound against two driven drums, or bed rolls. This is one of the original methods of winding and provides fast winding for large diameter, wide width, heavy rewind roll.

What materials are best suited for surface winders?

Films, foils, paper, and laminates that need precise roll density are best for surface winding.

What are two-drum winders, and how do they enhance roll quality?

Two-drum winders support the roll from the outside while winding. Rolls can be wound tighter at larger diameters.

What is roll density control and why is it important in surface rewinding?

Roll density control means keeping the roll from being too loose or too tight. It’s important because uneven rolls can cause problems in later processes like printing or laminating. Too tight, the material can ‘star’ and crush the core. Too loose, and the roll can wrinkle.

What type of knife systems can be used in a surface slitter?

Razor blades, shear knives, or score knives can be used depending on the material and cut quality needed.

How does the dual bowed roll system improve slit separation?

The first bow separates the slit strips slightly. The second bow prevents the material from continuing to spread. This creates separation of the individual rolls on the rewind, avoiding interleaving, or overlapping of the layers of the wind, which causes rolls to stick together.

Can surface winders be configured for different roll diameters?

Yes, they can be adjusted for small or large finished rolls depending on the job.

What safety features are standard on modern surface rewinders?

Guards, safety scanners, emergency stops, and automated load handling are common safety features to protect operators. These are linked to the machines PLC, or computer.

How do surface slitters manage high-speed web control?

They use advanced drives and tension controls to keep the material steady and aligned, even at high speeds.
