Product catalog summary

Overview of Measurement Systems for the Tire Industry
The document outlines various measurement systems used in the tire industry, focusing on the Profilometer and its variants, as well as other monitoring systems.

Profilometer Systems
The Profilometer is an automated, non-contact measurement system designed to replace manual checking with hand tools. It is used to verify the accuracy of newly-cut dies and monitor die wear during production. The system helps reduce the number of die trials, conserving time and raw materials.

Features & Specifications

Visual display overlays measurements onto the specified design.
Point and gage analysis measures thickness and width at breakpoints.
Conicity analysis compares right and left extrusion halves.
Regional analysis reports area and center of gravity for each region.
Statistical analysis allows data export for spreadsheet applications.
Experienced users report fewer die trials are needed.
Dies can be designed to tighter tolerances for difficult materials.

Profilometer Tread and sidewall extrusions can be no more precise than the dies used to make them. When a new die is cut it should be well-centered, so the Operator has the flexibility to optimize the extruder set-up. After some time in service, die wear can be uneven so that certain areas along the profile get excessive rubber flow. This is a very costly waste of raw materials. Unbalanced flow can also disrupt the symmetry of the tread - a factor that influences cured tire uniformity and balance. The Starrett-Bytewise Profilometer was developed as an automated, non-contact measurement system...
