DSS - Dimension Stability System

Modular Measuring System for the Investigation of the Dimension Stability of Paper / Board / Foils in Contact with Temperature or Liquids

DSS with wet stretch module	DSS with heat shrinkage module

DSS with Heat Shrinkage Module: Prediction of the converting properties of paper/board/foils concerning the dimension stability at thermal load up to 230°C
DSS with Wet Stretch Module: Measurement of the dynamics of the change in dimension of paper by means of one-sided contact with water based liquids under adjustable tension
Main applications:
- Decor paper, gypsum board, flatness of corrugated board, coating base paper, newsprint paper, offset printing paper,
  label paper, ink jet paper, kraft liner etc in contact with:
  - water
  - fountain solution
  - ink jet ink
  - melamine resin
  - gravure ink
- Runnability at professional laser printing machines and copy machines
- Register
  - four color laser printing
  - offset printing
  - rotogravure printing
- Fluting tendency with LWC papers
- Staple problems at professional offset-, copy and laser printing paper
Special applications:
- plastic foils,
- pre-impregnates,
- wall papers,
- filter paper

Modular measuring unit with modules to measure the wet stretch/heat shrinkage
Temperature adjustment via PC software
Includes measurement of paper moistness, humidity and ambient temperature
Change in dimension in MD and CD can be measured separately
Measuring results:
- Dimension-Time-Diagram
- Change in dimension at a selectable time point
Measuring range:
- Stretching up to approx. 27%
- Shrinkage up to approx. 5%
High accuracy
Measuring temperature: from ambient temperature up to max. 230°C (heat shrinkage)
Testing liquids:
- low viscous,
- aqueous liquids (wet stretch)
Efficient and user-friendly software
Export of the measuring data into MS EXCEL by a single mouse click
Easy to handle
Compact and robust construction
