Abstract:
1. A mandrel useful in the manufacture of coated belts, said mandrel comprising: a center tubular core having on each of its end portions; a first round metal plate attached to said tubular core, a second round plate secured to said tubular core, one of said first or said second round plates having a grooved channel concentrically machined adjacent the inside face of its inner perimeter, and the other of said first or said second round plates having a planar surface, the first round plate and the second round plate being separate from, and greater in diameter than, the center tubular core, a deformable O-ring nested into said grooved channel and sandwiched between said plate having said grooved channel and said planar surface of the other of said first and said second round plates, bolts positioned in said first round plate on its outer portion and adapted to be tightened evenly to squeeze said first and second round plates together thereby forcing a portion of said O-ring outwardly beyond outer perimeters of said first and second round plates, configured thereby to substantially equally space a belt to be positioned on and over said mandrel prior to precision coating said belt.
