SCREEN MATERIAL MANUFACTURING METHOD AND APPLICATIONS THEREOF

摘要

A metal screen material ( 32 ) having a flat side, in particular electroformed screen material, preferably seamless cylindrical screen material, comprises a network of dikes ( 34 ) which are connected to one another by intersections ( 36 ), which dikes ( 34 ) delimit openings ( 30 ). The height of the crossing points ( 36 ) is not equal to the height of the dikes ( 34 ). The metal screen material ( 32 ) or a combination thereof with a perforating screen ( 17 ) can he used as a perforating stencil for the perforation of film material ( 2 ), for example made from plastic material.
