摘要: A partially foam encased pocketed spring assembly is made in a fully automated assembly machine. A first foam rail is introduced into the assembly machine and glued to upper and lower substrate webs. A first string of pocketed springs is then glued to a side surface of the first foam rail between upper and lower substrate webs and glued to the upper and lower substrate webs. Additional strings are joined together to create a pocketed spring interior. A second foam rail is then introduced into the assembly machine and glued to an outer string and to the upper and lower substrate webs to create a core. Third and fourth foam rails are glued to the core.

摘要: A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.
