Title:
DOCTOR BLADE
Document Type and Number:
Japanese Patent JP2004202726
Kind Code:
A
Abstract:
To provide a doctor blade which shows outstanding plate stiffness which is essential to doctor performance, follow-up properties to a mating roll and a high wear resistance of the contact part with the roll as an important factor of production efficiency at a paper machine and besides, minimizes damage to be inflicted to the surface of the mating roll.
In the doctor blade 2 made of a fiber-reinforced resin obtained by impregnating the reinforcing fiber 2a with a matrix resin 2b, the bending modulus of the vertical direction V to the scraper line of action L is three times or more higher than that of the parallel direction H. Further, the matrix resin of the contact part with at least the roll 1 is constituted of a thermosetting resin.
