Micro Edge Guide for Solvent NeedleMicro Edge Guide for Solvent 2

Fiber Optic Sensor works along with Stepper Motor to align the solvent needle to the edge of the film.

Excellent Needle Positioning– This innovative device allows for excellent needle positioning without the worry of micro movements caused by roll changes, splices or slitter stops.

Micro Edge Guide– At 300 M/MIN, the micro edge guide will make quick movement to keep solvent at film edge.

Device Origin– This device was originally created for converters that ran blown film with uneven thickness and edges.

NO Longer Need to Stop due to Adjust Needle– Operators are continually adjusting the placement of the needle to the edge of the film. Operators worry about micro movements that will place the solvent inside or outside the required placement. Your operator will no longer need to adjust needle during each roll change, splice or slitter stops as the device automatically adjusts to the required edge.
