Before you choose
Questions about SF-373E
Does SF-373E include an automatic button feeder?
The selected SF-373E description confirms the stepper lifting system and electronic control. It does not establish an automatic feeder as part of the supplied package. Request one separately if it is needed.
Can it sew both two-hole and four-hole buttons?
These are the main applications described in the catalogue. Confirm the diameter, hole spacing, button thickness and clamp with a sample before ordering.
Can it sew shank buttons?
Do not assume that the standard two- and four-hole setup is suitable. Send the button and garment sample so any special clamp or attachment can be reviewed.
Is it a buttonhole machine?
No. It attaches the button itself. A buttonhole machine makes the opening that the button passes through; they are separate garment operations.
