Abstract
A belt conditioning method, apparatus and paper machine employing the method and apparatus are provided. The belt method and apparatus include multiple conditioning devices using chemicals to condition water impermeable surfaces of paper machine belts, such as transfer belts and prevent deposits from accumulating on the belts. In one embodiment, the belt supports a web at a first portion of the belt's loop and is separated from the web at a second portion. The conditioning apparatuses are placed in the second portion.

A paper machine belt conditioning method for a press section prior to a dryer section of a papermaking process for a continuous belt having a water impermeable surface and a face-side roll that contacts the water impermeable surface comprising the steps of:
- spraying a conditioning chemical onto a water impermeable surface of the continuous belt at a location where a fibrous web that travels with the belt has been pulled away from the belt so that deposits:
- (i) are removed from the impermeable surface of the continuous belt or (ii) are prevented from accumulating on the belt when the surface is remated with a portion of the fibrous web, which includes spraying the conditioning chemical onto a face-side of the continuous belt and the face-side roll.
