Systems and methods for feed control of rolled stock raw materials

Abstract

System and method for controlling the feed of a raw material disposed on a roll into a continuous or semi-continuous production process are provided. According to the disclosure, a user-defined amount of remnant material that is desirably left on the core of a roll of material when the roll is to be considered is depleted is provided as a process input, and a system according to the disclosure repeatedly evaluates and relates the stop length of material that passes through a process when a production line is stopped, the remnant material amount, and the amount of material currently present on a roll at various times during unwinding of the roll during process operation. Use of a system and/or method as provided enables operators of processes using rolled stock as a raw material to achieve heretofore un-attainably small amounts of scrap generation due to remnant material left on the roll's core.

Dependencies are inferred from the claim text.
