Abstract
ABSTRACT OF THE DISCLOSURE
Felt belts normally used in paper making are condition-ed after the newly formed paper is removed, by passing the belts over a narrow slot in a box under vacuum which extracts moisture and/or contaminants so that the belt is ready for reuse. Stain-less steel rods or the like are provided on each side of the slot and act as support guides for the belt, but these rapidly become worn and the sharp edges formed when the rods become worn, cut the belt which is a relatively expensive item in paper making machinery.
The present invention consists of holders detachably secured to the top of the box with the holders detachably supporting steel rods covered with a hard ceramic coating which resists wear. Fur-thermore, the rods are designed to be repositioned when the coating does wear, in order to provide the use of more than one working sur-face thus extending the life of the rods.

Description
BACKGROU~D O~ ~
In conventional paper making processes, the paper is form-ed upon high speed endless belts which absorb the moisture to the ............. extent where the sheet of partially formed paper can be separated from the belt and further processed, The felt belts are then nor-mally passed over conditioning boxes which extract the moisture and any contaminants which may be on the belts, thus preparing the belts for further use immediately, i'.' ., tending Felt conditioning boxes usually include an enclosure ex-. 20 /the full width of the belt, said enclosure being provided with a - ' .

; narrow transverse slot and a source of reduced air pressure. or vacuum is connected to the box thus drawing air downwardly through the belt passing over the slot and removing the moisture at the same time. -. ''' ".
The belt is supported and guided across the slot .
by stainless steel rods, but due to the high speed of the belt and the relative abrasive quality of the material used in the manufacture of the belts, the steel rods rapidly become worn and the sharp edges formed by this wear, initiates severe dama~
ge to the belts which are, of course, relatively expensive.

Proceeding therefore to describe the inventi on in de-tail, reference character 10 illustrates in oross section, a conventional conditioning box shown schematically and consisting 5 o~ an enclosure 11, being connected to a souree o~ reduced air pressure or vacuum, by means of connection 12.
.
~xtending across the upper side 13 o~ the box is a relatively narrow slot 14, it being understood that this slot extends ~rom one end to the other o~ the box which is the width o~ the ~elt belt 15 passing thereover and it should also be ap-preciated that the belt and box may be anywhere ~rom 12 to 30 feet in width, dPpending upon the design of the paper making machinery being used.
' ' .
The belt, which is an endless belt, travels at a fairly high speed in the direction of arrow 16 and passes over the slot so that air is drawn downwardly in the direction of arrow 17, ~.
said air passing through the belt immediately over slot 14 so that any moistura or the like is drawn from the belt which is then ready ~or ~urther use. :~
Stainless steel rods 18 (see Figure 6) are normally used to support the belt as it passas over slot 14, but due t-o the abrasive quality o~ the belt and the high speed, the belt engages the rod and wears same into a ~lattened configuration ~ .'''' ' .
; as indicated by reference character 19 and the sharp corners 20 formed by this flattened portion damage the underside of the belt.
