ABSTRACT:
A button sewing apparatus comprising a button supply device, a X-Y mover, a stay button chucking device, a surface button chucking device, a surface button turning device, a presser foot device, a thread guiding device and a thread holding device. Button neck wrapping is performed in a manner closely simulating "hand" sewing. After sewing both a stay button and a surface button to a workpiece, a sewing table makes a circular motion while keeping a needle entry as the center, and a thread is slidably clamped and guided to pass through a guide hole tentatively formed underneath a needle such that the thread wraps firmly around the button neck.
