Happy Cap Frame Setup
Every Happy machine we sell sews finished caps with a wide-field cap frame: about 14 in across on single-heads and 14.2 in on HCR3 multi-heads, so the front and both sides can sew in one hooping.

- Remove the flat hoop arms and fit the cap driver until it seats fully.
- Hoop the cap on the cap hooping station: sweatband folded back, cap pulled tight, strap locked.
- Slide the cap frame onto the driver until it clicks.
- Select cap mode so the design rotates and the speed drops.
- Use firm cap backing and sew from the center out.

FAQ
How big is the cap sewing field?
About 14 x 2.8 in on HCD3e and 14.2 x 3.1 in on HCR3 multi-heads.
Why are my cap designs out of register?
Usually loose hooping or a cap driver that is not fully seated. Use firm backing and sew center-out.
Do you sell extra cap frames?
Yes. Call 480-229-7806 with your model and we will match the frame.
