Abstract

This research on compression rolling of timber boards concentrates on the following aspects:

  1. Analysing the compression rolling process.
  2. Developing the instrumentation and the computerized data acquisition to acquire the parameters of compression rolling.
  3. Studying the effects of compression rolling on timber boards A theoretical model approaches the results of the experiment on compression rolling of timber boards. The surface and properties of timber boards are not obviously changed if the compression level is less than 10%, but are changed to a small degree when the compression level is increased from 10% to 17%%. There are splits and resin expellation on the surface of timber board when the compression level is more than 17%. The hardness on the surface of the timber boards is increased 4% at 15% compression level and 6.6% at 17% compression level. This thesis includes eight chapters. Its main contents are Chapter 3 -- theoretical analysis, Chapter 5 -- application of instruments and the computer, Chapter 6, -- experiment procedure, Chapter 7 -- results and Chapter 8 -- discussions and conclusions.
