Claim Text:
1. A method of making open-ended, reinforced, layered belting comprising; providing from a profile supply apparatus a length of profile layer having a top side and having a belt profile other than smooth on the opposite side; engaging a wrap portion of said profile layer in direct contact with a wrap portion of a rotating cylindrical mandrel having a mandrel profile complementary to said belt profile by pressing said profile layer directly onto said mandrel with an engaging roller positioned adjacent said mandrel; providing from a cord feed apparatus multiple tensile cords; applying at a predetermined cord spacing said tensile cords to said profile layer with a cord applicator positioned adjacent said wrap portion of said mandrel so that said cords are firmly attached to said profile layer before disengagement of the carcass portion from the wrap portion of the mandrel thus fusing said cords to the top side of the profile layer in parallel, lengthwise arrangement, forming a reinforced carcass; providing from a top-layer supply apparatus a supply of top layer material; and attaching with a laminator said top layer material to said top side of said reinforced carcass, thereby embedding the tensile cords between said profile layer and said top layer and completing said belting.
