Abstract
A power transmission which includes two harmonic differential drive units which are operable to oppositely vary the rotational speed of the two outputs in direct proportion to each other. The transmission is particularly suitable for use in controlling the two drive chains of a tenter so as to correct skew distortions in the fabric, and wherein the output of the tenter chains is oppositely varied without altering the mean speed of the two chains.
