Attachment for feeding reinforcing back buttons to a sewing machine

Abstract

An attachment for feeding reinforcing back buttons to a sewing machine which has a feed for main buttons to a button clamp which is positioned over a work material which is moved through a sewing station to sew the main button together with the back button which is fed beneath the material comprises a plate member which is mountable on a support arm of the sewing machine over which the material is fed. The attachment includes a plate member over which the material is fed which has a button chute guide groove defined thereon terminating in a button recess having a button aligning stop edge. The back button feed chute is connected to the plate for feeding back buttons in succession into the recess against the aligning stop edge. The guide groove is advantageously machined in an exchangeable plate which may attach to the work support arm of a sewing machine. The construction advantageously includes a compressed air nozzle which opens into the guide channel and is oriented to blow air into a guide channel space directly adjacent to the receiving element. The back button is covered by resilient retaining strips which may be displaced upwardly to permit removal of the button as the receiving workpiece material is moved along through the sewing station.
