Stanford 438 Slitter Rewinder

Same Stanford Control in a Smaller Footprint...

The 438 Slitter Rewinder is a cantilevered duplex differential center winder offering 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.

Ultrasonic unwind measurement, adaptive tension control, single or dual shaft winding, an on-board drive processor, and an intuitive 12” touchscreen renders the 438 the most technologically advanced slitter in it’s class.The 438 is well suited for a wide range of products including polyethylene, polypropylene, polyester, film laminates, self-adhesive label stock, paper and other flexible materials.

Accraply engineers a large selection of Stanford Doctor Machines®, a complete line of duplex differential slitter rewinders and shrink sleeve finishing equipment, as well as customized equipment.
