Abstract
159,144. Casablancas, F. Feb. 21, 1920, [Convention date]. Rollers and roller heads.-In arrangements for drawing rovings comprising one or more endless belts, the rollers that drive the belts are provided with saw-teeth so as to produce a regular movement of the belts without excessive weighting. The belts are guided by rollers 6 and plates 7. The rollers may be formed by stringing a series of washers with saw-teeth on a spindle
