Title: Lehr roll cleaning apparatus

Abstract: In situ lehr-roll cleaning apparatus includes a carriage supported within the space between first and second adjacent rolls, the carriage having a first set of elements contacting the surface of the first roll and a second set of elements contacting the surface of the second roll, whereby the carriage is movable back and forth along a path parallel to the rolls. A mechanism such as a rotating wire wheel disposed on the carriage is used to clean at least one of the first and second rolls as the carriage moves along the path and in between the adjacent rolls. The invention further including means for forcing the carriage away from an adjacent roll toward the one being cleaned so that the elements contacting the surface of the roll being cleaned are forced thereagainst to precisely position the cleaning mechanism relative to the surface. Means are preferably further provided for fine-adjusting the distance of the cleaning mechanism relative to the surface of the roll being cleaned. The preferred apparatus further includes a dust cover disposed over the carriage, and air-inlet and air-output ports formed through the cover to provide a recirculating air path to remove particulates and cool the apparatus.
