Abstract
Mattress borders are manufactured by advancing and severing a strip of border maerial into first relatively short lengths of the border material for forming handles, and second relatively longer lengths of the border material for forming mattress borders, folding and hemming the relatively short lengths to form tubular handles, temporarily storing the formed handles out of the path of advance of the strip of border material, aligning formed handles so that their tubular axes extend laterally across the longer lengths of material at desired handle positions, and serging ends of the handles to edges of the longer lengths of material to form mattress borders with handles. The invention also extends to apparatus for performing this method. The disclosed method and apparatus enable mattress borders complete with handles to be formed from a single strip of material
