<p>The method comprises the steps of providing a grooved drum (41), disposing the first polymeric material (16) in a non-cured form thereof about the drum (41), then subjecting the drum (41) to heat and pressure to cause the first material (16) to be forced toward the drum (41) and to exude into the grooves (42) to at least partially form the teeth (14), then substantially immediately cooling the first material (16) and the drum (41) to stop the curing of the first material (16) so that the first material is generally in a non-cured condition, then disposing the second material (21) in a non-cured form thereof about the first material (16) on the drum (41), and then again subjecting the drum to heat and pressure to cause the first and second material to be forced toward the drum (41) to complete any remaining unfinished portion of the teeth (14) and to be cured together.</p> |
