In situ grinding apparatus for resurfacing rubber belts and rollers
The present invention provides an apparatus for resurfacing a rotating elastomer substrate. The apparatus utilizes a motorized grinding wheel, said motorized grinding wheel rotating in a direction counter to the rotating elastomer substrate and having an axis of rotation parallel to the axis of rotation of the rotating elastomer substrate, wherein the perpendicular distance between the motorized grinding wheel and the rotating elastomer substrate is adjustable so as to control the amount of elastomer substrate that is removed; and a mount for said motorized grinding wheel, wherein said mount is located proximal to the rotating elastomer substrate that comprises a part of a production line and wherein the mount is capable of traversing parallel to the rotating elastomer substrate.
Compacting machine, positioning device and positioning method
A compacting machine for compaction a fabric including a feed roller, a retarding roller and a blade element configured to introduce the fabric to be treated between the feed roller and the retarding roller. The compacting machine also comprises a positioning device provided with at least one drive member configured to move one of the rollers with respect to the other of the rollers.

Method of fabricating a composite material part with improved intra-yarn densification
A method of fabricating a composite material part comprises fiber reinforcement densified by a matrix. The method comprises the following steps: making a fiber fabric by weaving yarns having an initial mean fiber percentage; and densifying the fiber fabric with a matrix. The fiber fabric is subjected, prior to densification, to one or more jets of water under pressure so as to reduce the mean fiber percentage in the fabric to a value lying in the range 20% to 45%.

Device for allowing narrow collar material to be processed through a standard fabric compactor
A device that attaches to a standard fabric compactor and allows narrow collar material to be processed through the standard fabric compactor. The device includes a pair of air openers. Each air opener includes an air inlet assembly and an air outlet assembly. The air inlet assembly of each air opener pulls air therein to form pulled air and pressurizes the pulled air to form pressurized air. The air outlet assembly of each air opener fluidly communicates with the air inlet assembly of an associated air opener, receives the narrow collar material therethrough, receives the pressurized air from the air inlet assembly of the associated air opener, and directs the pressurized air onto the narrow collar material, simultaneously from above and below, and in doing so, suspends the narrow collar material allowing the narrow collar material to be processed through the standard fabric compactor.

APPARATUS AND METHOD FOR PRE-SHRINKING A WET FABRIC PRIOR TO DRYING
An apparatus and method for pre-shrinking a wet fabric prior to drying. The apparatus includes, among other components, a balloon extractor station and a hydro-sizer compression station. The balloon extractor station removes some water from the wet fabric. The hydro-sizer compression station is operatively connected to, and disposed downstream of, the balloon extractor station, and compresses the wet fabric in a lengthwise direction, and in so doing, pre-shrinks the wet fabric prior to drying. The method includes, among other steps, extracting some water from the wet fabric so as to faun a hydro-extracted and wet fabric, compressing lengthwise the hydro-extracted and wet fabric so as to form a compacted and wet fabric that is now pre-shrunk prior to drying, and drying the compacted and wet fabric so as to form a compacted and dry fabric.
