Multi-needle embroidery sewing machine

摘要

A multi-needle sewing machine provided with a plurality of needle bars (8) including a specific needle bar (8) allowing detachable attachment of a punch needle (10, 61 to 66) that punch engraves a surface of a punch workpiece (W) in dot-by-dot strokes; a transfer mechanism (18) that allows detachable attachment of a punch workpiece holder (21), a detector (40) that detects the attachment of the punch workpiece holder (21) on the transfer mechanism (18); and a controller (41) that, when the attachment of the punch workpiece holder (21) is detected by the detector (40), executes a punch engraving operation on the punch workpiece (W) with the punch needle (10, 61 to 66) by selecting the specific needle bar by controlling a needle-bar selector/driver mechanism (17) and the transfer mechanism (18) based on punch engraving pattern data which is pre-stored or given by external components.
