Abstract
A method for manufacturing a cured, toothed belt is carried out upon a on a belt-making machine. The method includes incrementally molding sections of the belt with tooth spacing based on an estimated pitch circumference derived from a measured inside circumference, defining and measuring a length of a remaining uncured portion of the belt, the length of the remaining uncured portion of the belt being compared to a design length, a difference between the length of the remaining uncured portion of the belt and the design length being an error; and, adjusting a distance between a centerline of the first drum and the second drum, so that a compensating error is evenly distributed over the remaining uncured portion of the belt. One advantage of this invention is that the cumulative error generated by measuring and curing each section of the belt in an 'end to end' manner can be compensated by small adjustments made over a large section of the belt, preventing a large error in the last section of the belt.
