SPEEDWAY® SW7-3-32R2/223 – 3-Thread Rolled Hem Overlock Machine – Complete Setup, Table & Stand Included

Rolled Hem Specialist – “Baby Merrow” Finish

• Dedicated 3-thread rolled hem configuration engineered for extra-narrow, dense edges.
• Produces that classic “baby merrow” look: tiny, neat, rope-like edge ideal for high-end garments and décor.
• Perfect for sheer, lightweight and fine fabrics, as well as many knits where a narrow decorative hem is desired.
• Optimized stitch formation for rolled hems only, rather than being a generic overlock converted on the fly.

Smart Automatic Material Adjustment (SW7 Technology)

Like the rest of the SPEEDWAY SW7 family, the SW7-32R2/223 features Smart Automatic Material Adjustment:

• Assists in balancing stitch formation as you change fabric type and thickness.
• Helps maintain correct relationship between tension, stitch length and differential feed, reducing waviness or tunneling.
• Minimizes trial-and-error when going from one fabric to another (e.g. from a light woven scarf to a soft knit ruffle).

This means easier setup, less time lost tuning the machine, and more time actually sewing.

Materials & Applications

The SPEEDWAY SW7-32R2/223 is ideal for light and medium-light fabrics, such as:

1. Scarves & shawls – ultra-narrow rolled edge on chiffon, georgette, voile and other sheers.
2. Dresses & blouses – flounces, ruffles, hems and frills with a clean, tiny edge.
3. Children’s & babywear – delicate hems on knit or woven garments.
4. Lingerie & sleepwear – soft edges on lightweight fabrics and knits.
5. Home décor details – decorative edges on napkins, table runners and lightweight decorative pieces.

Whenever you want a fine, decorative rolled edge instead of a standard overlock seam, this is the right machine.
