摘要: In this process a plasticated acrylic glass strip is pressed by means of highly polished endless steel belt against form cylinder roller and brought, running in the common direction rotation, from plastication temperature to solidification temperature, thus achieving an accurate reproduction engraving on band continuously passing through.
