In addition, the present invention also has following advantage, namely the diameter by reducing compression roller 18 so that The nip pressure of being pointed out by the NPD1 line or the absolute value of wedge shape pressure be less than the value in the prior art, so that in technical process, makes coating 20 have enough viscosity in case contaminate and cause backing roll 12 dyeing. Distance between compression roller 18 and the backing roll 12 is with technical known control system adjustment. Above-mentioned distance can according to by be installed on the support 58, label is that 56 sensing device set-point is adjusted. The sensing device 56 of this and coating pan 24 teamworks can make coating pan 24 move both vertically under the effect of mattress 30, and mattress 30 is installed on the support 58 that is installed on the framework 22, as shown in Figure 4.
To shown in Figure 8, in the present invention's operation, coating 20 is taken up by coating roll 14, and coating 20 and paper web 16 are contacted at center line 60 places near backing roll 12 and coating roll 14 such as Fig. 4. Nip pressure begins to increase and keeps low absolute value in compression roller 18 zones at contact position 62. In addition, because the diameter of compression roller 18 is little, narrow than in the prior art of the nip width in NS1 zone. Therefore, for the coating of same model, the nip pressure absolute value is lower. This means to the invention provides a kind of effective means, coating can be dyeed to backing roll by the dip-dye of paper web 16. Coating 20 can apply to paper web 16 in the situation that keeps minimum dip-dye amount, therefore can make the coated paper with good printing quality. In addition, at branch P place, the irregular surface of the coating liquid film of roller warp-wise can be prevented from or can be alleviated at least, thereby so that striped or painted images can be reduced.
The invention provides a kind of coating equipment, as shown in Figure 3, this equipment has been avoided striped in the prior art and the problem of speckle. In addition, wedge shape pressure can be controlled by the compression roller 18 of optional position between backing roll 12 and coating roll 14. Like this, the quality that applies paper web can suitable nip condition be improved according to the type application of used coating and paper web.
