Abstract
A system for forming and attaching pillowtop attachment gussets and borders to panels, with the gusset or border material being fed from a supply into a sewing station. The gusset or border material is passed through a folder assembly that directs the gusset or border material into a sewing zone where it is attached to the panel. A ruffler mechanism engages and forms a series of ruffles in the gusset or border material as it is sewn about the corners of the panel.
Claims32
A method for finishing an attachment gusset for a mattress, comprising:
- moving a panel, with tension applied thereto, through a sewing zone;
- feeding a length of gusset material from a supply;
- receiving and directing the gusset material through a folder assembly into the sewing zone in a substantially flat lying attitude into engagement with the panel;
- attaching the gusset material about a peripheral edge of the panel;
- as a corner of the panel approaches the sewing zone, halting the application of tension to the panel and forming a series of ruffles in the gusset material as the gusset material is attached about the corner of the panel;
- and
- as an initially sewn portion of the panel approaches the sewing zone, cutting and folding a trailing end of the gusset material and sewing the folded trailing end to the panel.

A system for attaching a length of material to a panel, comprising:
- a sewing station adapted to receive and sew the length of material to the panel, the sewing station including at least one needle defining a sewing zone;
- an adjustable folder assembly for guiding the length of material toward the sewing zone;
- and
- a ruffler mechanism positioned adjacent said sewing zone for engaging and forming a series of ruffles in the length of material at desired locations along the length of material as the length of material is sewn to the panel;
- wherein said folder assembly and ruffler mechanism are pivotally mounted adjacent said sewing station so as to be moveable toward and away from said sewing zone.

A method for forming and attaching a border or gusset to a work piece, comprising:
- feeding a length of border or gusset material from a supply;
- guiding the border or gusset material into a sewing zone including adjusting the feeding of the border or gusset material with respect to a sewing needle at the sewing zone to set a spacing of a first edge of the border or gusset material from an edge of the work piece to a location at which the border or gusset material is sewn to the work piece;
- attaching the border or gusset material to the edge of the work piece at a location spaced from a first edge of the border or gusset material;
- as a corner of the work piece approaches the sewing zone, forming a series of ruffles in the border or gusset material as the border or gusset material is sewn about the corner of the work piece;
- continuing to sew the border or gusset material to the work piece about each corner thereof until an initial sewing point approaches the sewing zone;
- and
- cutting the border or gusset material and attaching a cut edge of the border or gusset material adjacent the initial sewing point to complete a sewing operation.

A method for forming and attaching a border or gusset to a work piece, comprising:
- feeding a length of border or gusset material from a supply;
- guiding the border or gusset material into a sewing zone;
- attaching the border or gusset material to an edge of the work piece at a location spaced from a first edge of the border or gusset material;
- as a corner of the work piece approaches the sewing zone, forming a series of ruffles in the border or gusset material by forming a sufficient number of ruffles to enable cupping of corner portions of the border or gusset material as the border or gusset material is sewn about the corner of the work piece;
- continuing to sew the border or gusset material to the work piece about each corner thereof until an initial sewing point approaches the sewing zone;
- cutting the border or gusset material and attaching a cut edge of the border or gusset material adjacent the initial sewing point to complete a sewing operation;
- and
- inverting the work piece after the border or gusset has been sewn thereto and applying cupped corner portions of the border about each corner of a foundation frame, with the work piece and a first portion of the border overlying the foundation frame and with a second portion of the border extending downwardly therefrom along sides of the foundation frame.
5 more elements
A method for forming and attaching a border or gusset to a work piece, comprising:
- feeding a length of border or gusset material from a supply;
- guiding the border or gusset material into a sewing zone and into a position overlying a portion of the work piece and spaced from an edge of the work piece by passing the border or gusset material through an adjustable folder assembly;
- attaching the border or gusset material to the edge of the work piece at a location spaced from a first edge of the border or gusset material;
- as a corner of the work piece approaches the sewing zone, forming a series of ruffles in the border or gusset material as the border or gusset material is sewn about the corner of the work piece;
- continuing to sew the border or gusset material to the work piece about each corner thereof until an initial sewing point approaches the sewing zone;
- and
- cutting the border or gusset material and attaching a cut edge of the border or gusset material adjacent the initial sewing point to complete a sewing operation.
