ABSTRACT:
A system for automatically stretching and stapling a foundation cover to a spring unit for a foundation, including a support table for supporting the foundation and cover, and a series of stretching/stapling assemblies or units positioned along the support table. The stretching/stapling assemblies include a series of tension applicators that engage and pull the cover taut against the sides of the spring unit of the foundation, while staplers are lowered into engagement with the cover and foundation frame, automatically stapling the cover to the sides of the foundation frame.
