Clamping device for machines used for transversally cutting convolutely wound logs of web materials

A log saw clamp for temporarily restraining a convolutely wound log of web material for a log saw, said log saw clamp comprising:

• a) a support structure, said support structure having a first and second cam disposed therein;
• b) a pair of opposed first and second paddles, said convolutely wound log of web material being disposable therebetween, each paddle of said pair of opposed paddles being capable of contacting engagement with a surface of said convolutely wound log of web material;
• c) a first and second linkage, each of said first and second linkages having a cam follower disposed thereon, each cam follower of said first and second linkages being connectively and operatively engageable with said first and second cam, respectively, each of said first and second linkages being operatively and fixably connected to said first and second paddles, respectively, at a distal end thereof;
• d) wherein, a force applied to both of said first and second linkages causes each of said cam followers attached thereon to translate within said respective first and second cams disposed within said support structure, each of said cam followers causing said respective first and second linkage to cause said respective first and second paddles operably and fixably attached to said distal end thereof to translate relative to said convolutely wound log of web material.
