Abstract
A method of forming a long cogged power transmission belt including extending a continuous looped vulcanizable belt preform element about a pair of axially parallel spaced support members, press-forming a first preselected length portion of the element disposed between the support members to form a first longitudinally extending series of cogs therein, vulcanizing the press-formed portion, press-forming a second, similar length portion of the element extending from the first portion and disposed between the support members to form a second longitudinally extending series of cogs therein continuing from the first series, vulcanizing the second press-formed portion, repeating the press-forming and vulcanizing operations if necessary until a final unformed portion of the belt extending from the last formed series of cogs and disposed between the support members has a length less than the preselected length, longitudinally stretching the final unformed portion to cause it to have a length approximately equal to the preselected length, press-forming the stretched final unformed portion to form a final longitudinally extending series of cogs therein to define a continuous series of substantially uniformly spaced cogs along the entire length of the looped element, and vulcanizing the final series of cogs.
