Before you choose
Questions about this machine.
Will one feeder handle every button from 8 to 32 mm?
The overall range covers different catalogue configurations and options. Send actual button samples, hole pattern, thickness and diameter so that the feeder, clamp and sewing pattern can be matched.
Is the listed power consumption 250 W?
The catalogue specifies 250 VA. The electrical supply and final configuration should be confirmed in the quotation; the VA value should not be replaced with a watt rating.
What should I confirm for a button-attaching machine with automatic feeder?
Send the actual button, diameter, thickness, hole arrangement and garment sample. Feeder compatibility and sewing pattern must both be checked. The supplied feeder and settings should be included in the confirmed quotation.
