Abstract
A method of producing synchronous belts having two or more tracks of teeth extending obliquely from the belt. The method includes forming an internal drum mold from a series of concentric rings, building a belt sleeve around the drum mold, vulcanizing the belt assembly, cutting the belt sleeve into widths and removing drum rings from the belt sections.
Claims8
A method of producing a synchronous drive belt (10) having teeth extending from a belt surface, comprising the steps of:
- assembling an internal drum mold (24), said internal drum mold having a first set of concentric molding rings (28), said first set of molding rings comprising adjacent right hand and left hand rings (30, 32), said right and left hand rings having teeth-forming grooves (34A, 34B) therein, said grooves on each of said right and left hand rings being separated by a pre-determined pitch (P);
- building a multi-plied belt band (60) around an internal drum mold (24);
- curing said belt band;
- segmenting said cured belt band into belt widths while said belt band is positioned on said internal drum mold;
- and
- removing said belt widths from said mold after said step of segmenting said belt band into belt widths wherein said step of removing belt widths comprises sliding said right hand ring away from a belt width in a first direction and sliding said left hand ring away from said belt width in a second direction.
