ABSTRACT:
A sewing machine for securing annular rings to a curtain along a line is provided with feed chute means for receiving the annular rings and feeding them sequentially to a sewing position. The feed chute means comprises a chute body having a track defined therein, a retaining tab adjacent the open end of the track for at least partially blocking the track to prevent discharge of annular rings from the chute body, a spring biasing the retaining tab to a track block position and a slot defined in the chute body adjacent said open end.
In use, the retaining tab blocks the track, with an annular ring in position over the slot so that the sewing machine can secure the annular ring over the slot to the curtain. After the annular ring is sewn to the curtain, the curtain is pulled to cause the retaining tab to yield while the sewn annular ring is removed from the chute body and the next annular ring is advanced to the position over the slot for sewing to the curtain. The retaining tab is biased inwardly after the annular ring is removed from the chute to retain the next annular ring in desired position. The operation continues sequentially until the desired number of annular rings are sewn to the curtain.
