How to Wind a Bobbin

简介

A bobbin is a small spool, usually made of plastic or metal, that holds the lower thread in a sewing machine. It works together with the top thread to form each stitch.

Make sure to use the proper kind of bobbin for your machine or tool.

The Patagonia® Expedition Sewing Awl uses a Class 15 bobbin to hold thread.

Follow this guide to add new thread to a bobbin using a sewing machine or a bobbin winder.

步骤 2 Set up the machine

Place the bobbin onto the bobbin winder pin.
Place the spool of thread onto the spool pin.
Secure the spool with a cap if your machine uses one.
Guide the thread through the thread path and tension discs, following your machine's manual.
This step is essential for maintaining proper tension during winding.

步骤 3 Prepare the bobbin

Attach the thread to the bobbin:
If the bobbin has a hole, thread the end through it from the inside out.
If the bobbin doesn't have a hole, wrap the thread around the bobbin manually a few times in the direction it will spin.
Turn on the machine if it's not already on.
Engage the bobbin winder by pushing the bobbin pin to the right or pressing a knob, depending on your machine.
Some bobbin winders will start automatically. Others will require you to engage the foot pedal.
Hold the thread tail for the first few seconds, then let go once it’s secure.

步骤 4 Wind the bobbin

The bobbin will spin and fill with thread.
Most machines stop automatically when the bobbin is full. If you want to stop the winder or if you run out of thread, disengage the bobbin pin.
Cut the thread and remove the bobbin.

步骤 5 The finished bobbin

The ideal bobbin has:
Uniform distribution: The thread should be wound in smooth, uniform layers across the entire bobbin. There are no peaks, dips, or bunching in the middle or at the edges.
Firm tension: The thread should be tight and compact. Each layer lies flat and smooth without loops or tangles.
Proper fill level: When full, the thread shouldn't extend past the rim of the bobbin.

Loosely wound: A messy bobbin leads to messy sewing. The bobbin must be wound tightly and with consistent tension to function properly—this applies whether you're using a sewing machine or an Expedition Sewing Awl. Unwind the bobbin, re-thread the machine, and try again. Make sure the thread passes through all tension guides.
Not winding: Make sure the machine is in bobbin mode. This may involve flipping a switch or pressing a knob. On some machines, the foot pedal must be pressed to activate the winder.
