ABSTRACT:
A method of forming a power transmission belt including the steps of: providing a first layer made from rubber and having first and second oppositely facing sides; providing a mold; pressing the first side of the first layer conformingly against a surface on the mold having alternating projections and recesses to thereby form alternating teeth and troughs on the first layer; locally pressing the second side of the first layer at locations coinciding lengthwise with the teeth to thereby eliminate or prevent the formation of discrete holes; and joining the first layer, having the alternating teeth and troughs thereon, to at least one other component to define the power transmission belt.
