ABSTRACT:
Apparatus for simultaneously winding several webs of developed photographic paper on the cores of reels whose flanges rest on pairs of supporting rollers one of which is driven by a discrete variable-speed motor has a loop former for each web. Each loop former adjusts a potentiometer in dependency on changes of tensional stress upon the corresponding web, and the potentiometers cause control circuits for the corresponding motors to reduce the speed of the driven supporting rollers as the diameters of convoluted portions of the webs increase. The webs are fed at a constant speed. The supporting rollers consist of rubber to reduce the noise as a result of contact with the flanges of the respective reels, and to reduce the likelihood of slippage of the reels.
