DEVICE FOR MATERIAL APPLYING TO STRIP AT LEAST ONE PART OF REMOVABLE LAYER SURFACE OF TRANSFERABLE FOIL AND ASSOCIATED APPLICATION Russian patent published in 2009 - IPC B41F19/06 B29C59/04 

FIELD: mechanics.

SUBSTANCE: device contains at least one backup roller, one press roller and one adjusting device. The press roller presses material and transferable foil strips to backup roller. The press roller is installed by means of at least one spring system in terms of pneumatic and hydraulic elements and spring-loaded. The adjusting device changes elasticity coefficient of spring system to change press roller pressing force to backup roller. The spring system is formed by membrane spring. The membrane spring is comprised of a membrane cavity and membrane. The membrane splits the cavity into the primary and secondary parts. There is a piston in the secondary part, which is rigidly connected with the membrane. The piston transfers elastic effort to press roller. The device is used to produce protection elements on valuable documents or to produce structural and decorative elements in architecture and other engineering branches or packing materials or elements in electrical or electronic industry.

EFFECT: simple and fast adjustment of press roller pressing effort on backup roller.
