Abstract: The article disclosed, with method for its manufacture, is a pocketed-spring construction made by joining juxtaposed subassemblies or modules formed by the interconnection of two rows of pocketed springs at intervals of two springs or more according to the resistance to compression desired. Various module joinder techniques are shown and described.

Abstract: The subject matter is a cushion core construction in which individual elements of cushion material in plug-like form are connected together in a string by capturing them between two strips of flexible sheet material which are joined together between adjacent elements to hold the elements in place. The preferred structural unit is a two-row module formed by joining two such strings at intervals of at least two elements to enable them to stand alone, and to facilitate their handling in their assembly with like modules to form a more extensive core.

Abstract: This method and apparatus contemplate the making of pocketed springs for mattresses and cushions by inserting compressed springs at intervals along and between the plies of a folder two-ply strip of sheeting, maintaining the springs compressed therein while seaming the edges of the plies to form a sleeve about the compressed springs as the strip is drawn lengthwise toward a release point at which each spring is free to expand to spread the plies. This transposes the edge seaming to mid-height of the spring. A previously made cross seam incorporating the transposed edge seaming limits the forward movement of the spring and a further such cross seam made behind the spring encloses the spring within an individual pocket of the sleeve. The repetition of spring release and cross seaming behind each spring released produces a string or chain of pocketed springs with the closing seam of the sleeve at mid-height of the springs.

Abstract: Disclosed are pocketed upholstery springs in strip form characterized by placement of the closing seam midway between the ends of the springs of the strip, with the marginal flaps of the pocket strip fabric outwardly of the closing seam folded over as a two-ply belt and incorporated into the cross seams which define the pockets about the springs. Adjacent rows of such strips are joined together by tacking through their respective belts at the cross seams to form two-row modules for ease of mattress/cushion assembly, or to form full-size mattress/cushion constructions by joining row upon row.
