Stanford 438 Duplex Slitter Rewinder Machine

The Stanford 438 duplex slitter rewinder offers the control you expect from Stanford in a smaller footprint.

This high-quality cantilevered duplex differential centre winder offers converters an affordable, easy to operate, compact solution to their slitting needs.

This versatile slitter features constant tension rewind via load cells, or the constant torque rewind, which is a hallmark of Stanford slitters.

The Most Innovative Slitter in Its Class

No other compact slitter rewinder compares to the 438 by Stanford.

Ultrasonic unwind measurement, adaptive tension control, single or dual shaft winding, an onboard drive processor, and an intuitive 12” touchscreen make the 438 the most technologically advanced slitter in its class.

The 438 is very suitable for a wide range of films, foils, papers and more, including polyethylene, polypropylene, polyester, film laminates, self-adhesive label stock, paper and other flexible materials.
