An improvement is provided in a method of making a toothed belt construction that has a toothed surface means and that comprises a belt sleeve from which individual endless belts are subsequently cut in a conventional manner, the belt sleeve having a preformed fabric means lining the toothed surface. The method includes the first step of forming the preformed fabric to have serially disposed tooth-shaped projections throughout its length so as to line the toothed surface thereof. The fabric is disposed onto an externally toothed cylindrical mould member used to form the belt sleeve. The belt sleeve is formed on the mould member with material so that the fabric forms part of the belt sleeve with the material. The preforming fabric is formed from an endless tubular sleeve that has the tooth-shaped projections formed therein while the fabric means is still in the endless tubular sleeve form thereof. The endless tubular sleeve in its pre-formed condition is disposed on the mould member by axially sliding the sleeve in a telescoping manner onto the mould member before the step of forming the belt sleeve. The fabric is disposed in the endless tubular sleeve form thereof between a pair of cooperating and telescoped cylindrical mould members respectively having teeth that index with each other to form the tooth-shaped projections of the fabric. One of the mould members is formed by deforming a first sleeve of polymeric material under heat and pressure against a cylindrical mould device that has teeth thereon. The first sleeve is removed from the mould device and is inverted. A second sleeve of polymeric material is deformed under heat and pressure against the inverted first sleeve to form teeth in the second sleeve. The sleeves are inverted while the second sleeve is against the first sleeve. The inverted sleeves are separated to comprise the cylindrical mould members to be utilized to form the fabric therebetween.
