Method and apparatus for continuously preheating a mat for the manufacture of particle, fibre or like boards

摘要

A method and apparatus for continuously preheating a mat for the manufacture of particle, fibre or like boards are described, which make possible particularly inexpensive, rapid and easy-to-effect preheating by the fact that, after precompression of at least one of the broad sides of the mat into the preheating zone over the entire area a heated fluid is introduced into the mat and at least partially passed through. <IMAGE>
