Stress Analysis and Energy Estimation in Cold-Roll Forming Process

In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...

Fibre flocculation during twin- wire roll forming

At the division of Paper Technology a forming unit consisting of headbox, forming roll unit and reservoir system for suspension recirculation has been constructed, with the main purpose to experimentally study the paper forming event by visually following the fibre flow phenomena in the forming zone. The effect of various running parameters upon the pressure distribution, which is in correlatio...

Design Parameter Analysis of a Roll-to-Roll Printing Machine

The stability of multi-input and multi-output web-tension systems is an important factor that is required for the roll-to-roll printing machines. This paper analyzes stability for design parameters of a web-tension system of a high-speed gravure printing machine. Analyzed parameters include moment of inertia of the passive dancer, viscous friction coefficient of the dancer system, distances fro...
