DEVICE FOR APPLICATION OF POROUS COATS ON TAPE Russian patent published in 2007 - IPC C23C14/56 C23C14/24 

FIELD: devices for application of porous coats on tapes; manufacture of electronic components, magnetic media for recorders; application of decorative coats.

SUBSTANCE: proposed device has vacuum chamber, evaporator, winding and unwinding shafts, upper, middle and lower guide rollers and deflecting rollers for carriage of tape. Rollers are made in form of cooled cylinders mounted above evaporator so that tape might embrace the rollers over broken line forming twin sections of tape between guide rollers. Twin sections of tape between guide rollers are located symmetrically relative to the vertical drawn from evaporator center. Additional guide rollers located between lower and middle rollers for forming twin sections of tape are located at acute angle relative to each other. All guide rollers are so mounted that sections of tape may pass between them forming angle of 68-78^o between straight line connecting the evaporator center with any point of these sections and normal to this point of section. Additional guide rollers may ensure adjustable force of tension on tape sections.

EFFECT: enhanced efficiency.
