Davis-Standard: New Industrial/Agricultural Film Winder Ensures Operator Safety

An innovative industrial/agricultural film winder from Davis-Standard incorporates an automatic cross-cut knife and transfer mechanism to ensure reliable transfers to a new core and improved operator safety. Developed in 2004, the winder addresses an industry safety issue by replacing manual cut and transfer with an automatic transfer when processing heavy films or gusseted, folded films.
Most turret winders used in industrial and agricultural film applications are not equipped to mechanically cut and transfer these thicker types of films. Typically, this requires an operator to perform the task manually, often resulting in a safety hazard because of the high injury rate to upper body limbs. Davis-Standard’s winder utilizes a traversing cross-cut rotary shear that is motor driven across the film. Processors can take advantage of shafted and shaftless auto-cut with this automatic core transfer. With this mechanism, all an operator has to do is push a button.

The winder is available in widths from 40 to 200 inches (1,000 to 5,000mm) wide and is capable of cutting through eight folds of film, each 6 to 8 mil thick. The capacity to cut folded films is essential as most automatic, snap-knife cutting devices do not permit this and pneumatic driven razor knives often stall, causing processing delays. In addition, the automatic core transfer improves processing efficiency because of a short tail start on the new core and better roll geometry. Initial feedback from customers using the winder has been very positive.
