Abstract
A method and a system for preventing the accumulation of polarized foreign particles on a support surface of support elements positioned in contact with a moving fabric in a paper making machine. An electrically conductive fabric support surface of a support element is charged with an electrical charge of like polarity to the polarized foreign particles whereby the polarized foreign particles will be repelled from the support surface.

A method of preventing the accumulation of polarized foreign particles on a fabric support surface of support elements positioned in contact with a moving fabric in a papermaking machine on which there is supported a pulp stock having polarized foreign particles comprising connecting an electrical charge to a conductive portion of said support elements, said electrical charge being of like polarity to said polarized foreign particles whereby said polarized foreign particles will be repelled from at least a portion of said fabric support surface.
In a papermaking machine support element having a fabric support surface positioned in contact with a moving fabric supporting a pulp stock having polarized foreign particles, the improvement comprising said support element having at least a conductive portion thereof connected to a power supply to apply to the conductive portion an electrical charge of like polarity to said polarized foreign particles to repel said particles from at least a portion of said fabric support surface.
