Abstract
An innerspring construction including adhered strings of pocketed coil springs is provided together with a method of manufacture. Each string is defined by a series of coil springs connected and encased by a fabric cover. The strings are connected to each other by an adhesive applied between the lines of tangency of adjacent coil springs. A method is provided for assembling such a construction. A hot melt adhesive applicator traverses a string of pocketed coil springs depositing a precise amount of adhesive on each coil jacket. A second string is positioned on the first and pressure applied thereto. The applicator then traverses the second string in the same manner as the first. For purposes of efficiency, it may traverse the second string in the opposite direction from which it originally moved with respect to the first. The sequence is repeated until an innerspring construction of desired size is created.
