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
A method of manufacturing mattress borders, comprising the steps of severing border material in the form of a strip into first relatively shorter lengths of the border material for forming handles, and second relatively longer lengths of the border material for forming mattress borders, temporarily storing the relatively shorter lengths out of of the path of advance of the strip of border material, aligning the relatively shorter lengths on the longer lengths of material at desired handle positions, and attaching ends of handles, formed by the relatively shorter lengths, to the longer lengths of material to form mattress borders with handles.
Apparatus for forming mattress borders, comprising means for advancing mattress border material in the form of a strip through metered lengths, means for severing the advanced and metered material into first relatively shorter and second relatively longer lengths, means to store the shorter lengths out of a path for advance of the strip to form said longer lengths, means to align the shorter lengths from said storage means on the strip at predetermined intervals in the formation of said longer lengths, means to advance aligned handles, formed by the shorter lengths, with the strip, and means located downstream of said alignment means to secure ends of the aligned handles to the strip.
