ABSTRACT:
A method of making a toothed belt. A toothed belt is made by guiding a strip of fabric to pass through a thermosetting resin to soak it with thermosetting resin, then the soaked fabric is guided to pass through a pair of toothed rollers to form a series of toothed grooves thereon, thereafter the fabric is guided to pass around a plane roller and simultaneously rubber material is fed into the space between the outer peripheral surface of the plane roller and said fabric. Then, the fabric is wound onto a cylindrical mold having corresponding toothed grooves thereon and its two ends are glued together to loop around the cylindrical mold, then reinforcing cords and rubber sheets are covered over the fabric. Finally, the rubber material is vulcanized to form a toothed belt. Fabrics treated by the method demonstrate considerately greater flexibility or extendibility to comply with bending when under operation. Furthermore, the tooth contour of the belt will be more accurate than conventional ones. Also, the two flat ends of each piece of the fabric are coated with a thin layer of rubber material which can also be used as an adhesive, this will facilitate the gluing of the two ends of each piece of fabric.
