On-Line Profilometer (OLP) Real-Time Measurement System

The On-Line Profilometer (OLP) is an on-line, real-time measurement system for continuously monitoring key profile dimensions in complex tread and sidewall extrusions. OLP employs CrossCheck™ line laser sensors manufactured by Bytewise. These multi-sensor systems acquire thousands of data points around the profile and match them to a CAD template, where key measurement thickness and width parameters are extracted. Measurement parameters are compared to allowable control limits and displayed on the operator’s terminal with a green/yellow/red (pass/caution/fail) status indicator. Profiles are acquired at a user-set rate up to 14 profiles per second and all measurements are recorded to a history file. OLP is available in several width sizes, from 150mm to 1200mm, in 150mm increments.
