<p>A method of making a plurality of toothed belt constructions and a set of such belt constructions are provided, the method comprising the steps of disposing tubular sleeves (34) of stretchable fabric material (25-25B) respectively onto a plurality of toothed mold members (31-31B) having different diameters, forcing mold material (35-35B) against the outside surfaces (37) of the sleeves (34) to tend to stretch the fabric material (25-25B) into the grooves (33-33B) of the toothed mold members (31-31B) as the mold material enters the grooves of the mold members so that the resulting toothed belt constructions (20-20B) will have the fabric material (25-25B) thereof carried in certain positions relative to the respective teeth (23-23B) thereof, and forming the sleeves (34) from the same fabric material and with the same diameters in the nonstretched conditions thereof.</p> |
