PRODUCTION LINE TO APPLY COATING ON LENGTHENED CYLINDRICAL PIECES Russian patent published in 1995 - IPC

FIELD: application of coatings on metal pieces. SUBSTANCE: production line of coatings application has mounted in series feeding roller conveyer, first pressing rollers support with lengthened cylindrical pieces pressing mechanism, clearing chamber, metal application chamber, second pressing rollers support, receiving rollers conveyer, located between rollers conveyers and pressing rollers supports rotation rates equalizing mechanisms. Rollers conveyers supporting rolls are located at similar angle to longitudinal axis of production line. Feeding and receiving rollers conveyers have rates exceeding rotation rates of pressing rollers supports and rates equalizing mechanism is made in the form of mounted between driving shaft of pressing rollers supports and driving shaft of rollers conveyers usually closed friction coupling of adjustable torque, that has pressing bearing and flexible member of adjustable rigidity in mechanism of its closing. This provides increase of productivity of the production line and quality of coating due to removal of gaps between pieces and uniformity of their movement and rotation with lower wearing of production line carrying members. EFFECT: increased productivity and quality. 9 cl, 8 dwg
