ScrapStopper^TM is a High Precision Unwind Controller which is designed to provide the converting industry a solution to save money by reducing the amount of material remaining on an unwind core. This product has helped many customers reduce costs by consistantly and accurately timing a Splice or Line Stop closer to core then their current means. The ScrapStopper^TM calculates many Key Unwind Variables, like Diameter, Material Gauge, Footage Remaining, Line Speed, Roll Footage Totalizer, and more. With the benifits of a dedicated processor and high speed io, the ScrapStopper^TM has proven a reliable and inexpensive solution to reducing material waste.

Auto Splice

A standard application of ScrapStopper^TM is to serve as a trigger of an Automatic Unwind Splice. The ScrapStopper^TM accurately calculates the footage remaining in the unwind roll. Knowing the remainging footage the operator has control of the splice timing by dialing in a user entry setpoint for the footage amount to leave on the roll. Because of the consistancy and accuracty of the system customers are able to produce more sellable product and less scrap.

Auto Stop

Another standard application of the ScrapStopper^TM is to provide a means for and accurate Automatic Stop at Unwind Core. Many lines can only make sellable product while running at a consistant line speed. It is cost adventagous to stay at line speed as long as possible to before issueing a line stop. Key feature of using the ScrapStopper^TM is it accurately calculates the footage required to decel to a stop at the current line speed. The system can be configured for both lines with a Fixed Decel and S-Curve, Using the ScrapStopper^TM for an automatic stop, the system will trigger a stop based on Calculated Footage Remaining on the Roll, and the Footage Required to Decel to zero speed. A setpoint is exposed for the Operator to control the final footage remaining on the core when fully stopped.
