Button sewing machine

摘要

A button sewing machine has a sewing needle reciprocatingly movable in response to rotation of a main shaft and a button gripping assembly having gripping portions for gripping and releasing a button and movable across the path of reciprocating travel of the sewing needle, the sewing needle and the button gripping assembly being operable together for sewing the button to a fabric. The button sewing machine includes a detector for detecting whether the button is gripped by the gripping portions. After it has been confirmed that the button is gripped by the gripping portions, the main shaft is driven by a control assembly for enabling the sewing needle to sew the button to the fabric.
