Using the center line you developed in squaring both belt ends, measure in 5" from each belt end to determine the center point. With either a template, straight edge or preprinted finger tape, lay out the "fingers" which will be a minimum of 3" long or deep x 1" wide, starting from the center point of each belt. The lined "fingers" can then be cut with either a utility knife or a steel rule die.

The splice area may have become soiled with dirt, oil, or grease during installation. Make sure to clean this area with either MEK or Acetone and then wait one minute for the solvent to evaporate.
In setting up the water cooled vulcanizer, the bottom plate should be covered with Teflon coated fiberglass.
Having arranged the bottom platen, place the recommended number of plies of NOVITANE urethane foil on top of the Teflon coated fiberglass, position so that the foil extends beyond the finger area by a minimum of one half inch.
Position the belt with the splicing area on the foil and clamp into place making sure the center line is aligned straight on both ends. Double check the squareness of the belt ends using a square before clamping. Place metal edge irons along both edges of the splice area to serve as a side dam. Fill in the remaining open platen area with metal shims of the same thickness, do not use remnant pieces of the belt you are splicing. Finally, place the Teflon coated fiberglass and/or fiberglass epoxy board or steel cover plate over the foil and assemble the top platen to the bottom platen.
Pressurize the platen to the recommended temperature. After reaching the proper temperature, allow the splice to cure according to the recommended cure cycle. The cure cycle reflects time at temperature without consideration given to individual press situations. The press situation involves watt density of the press heaters versus various types of platen covers which can affect the heat-up rate of a belt. In order to attain the recommended belt temperature levels, the temperature of the platens may have to be increased approximately ten degrees higher.
