Tactilus® Technology

Tactilus® is a unique air bladder based sensor system that provides an unprecedented combination of accuracy, repeatability and reliability in the surface sensing world. Essentially an "electronic skin" that records and interprets pressure distribution and magnitude between any two contacting or mating surfaces and assimilates that data collected into a powerful, yet user-friendly, Windows based tool kit. Each Tactilus sensor is carefully assembled to exacting tolerances and individually calibrated and serialized. The architectural philosophy of Tactilus is modular allowing for portability, easy expansion, and simultaneous data collection of up to 6 discrete sensor pads. Tactilus employs sophisticated mathematical algorithms that intelligently separate signal from noise. Our proprietary sensor design ensures the most robust sensor in the industry - an investment that will sustain thousands of uses.

The sensor is placed into the press

The sensor is positioned and ready to collect data regarding the planarity of the shoe

Benefits of the Double-Backer System

  • Immediate improvement in glue adhesion optimization
  • Extend shoe life
  • More uniform heat distribution
  • Extend belt life

Zoomed in view of sensing points

Ensuring planarity and proper pressure level of the shoes and rollers in a Double-Backer press is one of the key drivers in maintaining board quality. But the benefit of pressure measurement is not just in product quality but also bears out in the form of improved belt longevity. The Double-Backer has to maintain a delicate balance: It must apply heat through the shoes or rollers to the board, but it must not have to much pressure where it will cause drag.
