Gralex Unwind Stands Allow One-Person Changes

Published: March 06, 2012

LEWIS CENTER, OH | Model SRS stationary unwind stands from Gralex allow one-person roll changes, require no tools for changeovers, provide automatic self-adjusting friction brakes, handle unwind speeds to 100 fpm, and include fork lift slots for easy moving.

Friction brake prevents roll runaway without any manual input, so stands work well for intermittent feed systems. As the roll becomes smaller, the reduced weight automatically decreases the frictional force which holds back the roll. Less braking force is required because the momentum of the roll is less.

Stands are designed with lightweight shaft and core chuck assembly and are adjustable to different widths of material by using no tools to pull out the locking ring and moving the core chucks on the shaft by hand. Then, simply push ring back in, to lock core chuck in place.

The model handles rolls of paper, paperboard, plastic film, foil, and other roll materials from 18–to 39 in. wide to 72 in. in dia and roll weights from 3,500 lbs (for 18-in.-wide rolls) and 7,600 lbs (for 39-in.-wide rolls).
