KRK Sym-size Press - OpTest

Fabrication of coated paper uses various types of coating. This size press is designed for use in the laboratory simulating the practical Sym-size press. It is composed of applicator roll; back-up roll and rod bar to make uniform color coats. The specimen, that is, sheet paper is applied on the back-up roll, and it is rotated at a high speed and made to contact the applicator roll to perform coating. Tests can be made in various conditions by changing the rod bar interval, contact pressure, rotation speed of the applicator roll, and press pressure of the back-up roll.
