Question

Which of the following allows the bobbin to be fitted in the oscillating hook?

• A. Face plate
• B. Throat plate
• C. Slide plate
• D. Spool pin

Hint:

The Throat Plate stays fixed during sewing; the Slide Plate is what you move to change the bobbin.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks to identify the part of a sewing machine that is moved or opened to access the bobbin area.

Step 2: Detailed Explanation:

• The Slide Plate (C) is a rectangular metal cover located just in front of the presser foot on the bed of the machine. It "slides" open to allow the operator to insert or remove the bobbin case.

• The Face Plate (A) is the cover on the left side of the machine head that hides the needle bar and take-up lever mechanisms.

• The Throat Plate (B) is the metal plate directly under the needle that has a hole for the needle to pass through and slots for the feed dogs.

• The Spool Pin (D) is the upright pin on top of the machine that holds the spool of upper thread.

• Thus, only the Slide Plate provides the "access" to the internal bobbin mechanism.

Step 3: Final Answer: The slide plate allows the bobbin to be fitted in.
