| Contd:- -3- hsl/LG5.9.21. ----------- In U.S.A. I was shown a clutch on a Mack Truck (which has a similar reputation to the "Leyland" in England), they claim that they obtain very much better results by using the fabric as the driven member. The advantages are:- 1. Instead of the heat piling up into the light steel disc, it is transferred to the flywheel which can easily dissipate it. 2. The driven member still has very little inertia. 3. There would be no risk of it buckling. Mr. Frood was of the opinion that he could make a fabric which would stand up very successfully. He said they had a greater tensile strength in their material than any other similar material. "We will bring to W.W. samples of plates which we have removed from clutches.
