Feeding flow in through one side of spring pipe,spray to the
surface of paper from spring stick,make smooth by blade,surplus
costing materical back flow from receive device.
(Figure 1)
To prevent streak caused by little pellet pile up at the edge
of blade,use blade vibrating device and eliminate blade streak
and Avoide wear and tear blade.So make coating film smooth
and improve paper quality.
(Figure 2)
Through coating flow adjust device,can accurate control
back up roll’s pressure comes from blade,So can machinical
control the trickness of coating film and suit for the demand of
and kind of paper.
