Method of making mattresses
View Patent ↗A pillow top mattress is made by first folding a mattress core border strip lengthwise to form at least one integral pillow top border, cutting diamond-shaped notches out of the folded edge, and sewing the free edges of the notches together to form mitered corners. The strip is cut to length, and after its ends are joined together to form a band, it is pulled over the mattress core. The border strip is then secured to the core material, and pillow top insulation is added before a pillow top panel is sewn to the free edge of the border strip.
1. A method of making a pillow-top mattress, said method comprising steps of
folding a strip of border material lengthwise to form a border strip having folded edges defining a central mattress border portion and lateral pillow top border portions,
cutting miter notches along the folded edges of the border strip at intervals determined according to the size of the mattress being produced,
drawing adjacent pairs of edges of the notches together and connecting them by sewing, to produce mitered corners in both the mattress border portion and the pillow top border portions,
cutting the border strip to length and joining its ends together,
pulling the border strip over a mattress core,
placing pillow top padding on at least one side of the core,
placing a pillow top panel over the padding, and
sewing the pillow top panel at its periphery to a free edge of the border strip.
2. A method of making a one-sided pillow-top mattress, said method comprising steps of
folding a strip of border material lengthwise to form a mattress border strip having a folded edge, a free edge and a pillow top border portion,
cutting miter notches along the folded edge of the border strip, and the free edge of the mattress border portion, at intervals determined according to the size of the mattress being produced,
drawing adjacent pairs of edges of the notches together and connecting them by sewing, to produce mitered corners in both the mattress border portion and the pillow top border portions,
cutting the border strip to length and joining its ends together,
pulling the border strip over a mattress core,
placing pillow top padding on one side of the core
placing a pillow top panel over the padding, and
sewing the pillow top panel at its periphery to the free edge of the pillow top border.
