Abstract
A tenter frame drive is illustrated wherein auxiliary power operated means are provided to drive the sprockets at the entrance end of the chain runs, opposite the main drive at the exit end. The auxiliary drives remove the slack in the chains which normally occurs at the exit end opposite the point of driving engagement of the sprockets in such a fashion as to avoid chattering of the chain and tenter clips while providing for a division of the forces so as to some extent reduce the maximum tension in the chain, and at the same time insure sufficient tension for proper gripping of the web at the entrance end of the tenter.
