Abstract
Abstract 1. A method of making multi-ply rubber core-knit fabric sheath belts used in garment waistband construction, said method comprising the steps of folding and creasing a knit fabric strip to form a closed sheath, feeding a rubber core, consisting of at least one rubber strip, to said sheath, opening said sheath to receive said rubber core, applying a bonding agent between said rubber core and said open sheath, closing said sheath upon said rubber core, and applying heat and pressure to said closed sheath to set the bonding agent and thereby bond the sheath and rubber core together. 2. A machine for performing the above listed method steps, said machine comprising folding and creasing means for folding and creasing a knit fabric strip to form a closed sheath, feeding means for feeding a rubber core, consisting of at least one rubber strip, to said sheath, unfolding means for opening the closed sheath to receive said rubber core, applicator means for applying a bonding agent between said rubber core and said open sheath, refolding means to close the sheath upon the rubber core, and heating and pressure applying means for applying heat and pressure to the closed sheath to set the bonding agent and thereby bond the sheath and rubber core together.
