Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key innovation?The lockstitch mechanism, enabling strong and secure seams
2. What is the primary function?Automated stitching of fabric using needle and bobbin threads
3. How does a lockstitch sewing machine work?The needle goes through the fabric, leaving a loop of thread. A hook grabs the loop and ties it to the lower thread on a bobbin, making a strong stitch.
4. Why did sewing machines help people?They made clothes faster and cheaper, so more people could buy and wear clothes.

Lockstitch: A type of stitch formed by interlocking two threads, one from the top and one from the bobbin, creating a durable seam.
Shuttle: A component in lockstitch sewing machines that carries the bobbin and interlocks with the needle thread.
Feed Mechanism: The system (often 'feed dogs') that moves the fabric incrementally under the needle to create continuous stitches.
Tension: The tightness of the upper and lower threads, crucial for creating a balanced and secure stitch.
