A needle clamp on a sewing machine is the component that securely holds the sewing machine needle in place. In some designs, particularly in child's sewing machines, the needle clamp features a unique configuration.
Function and Design of a Needle Clamp
The needle clamp's primary function is to maintain the needle's position, ensuring proper alignment with the hook or bobbin case for stitch formation.
- Securely Holds the Needle: Prevents the needle from moving during sewing.
- Ensures Proper Alignment: Critical for accurate stitch creation.
- Easy Needle Replacement: Allows for quick changes when needed.
Unique Features (Specific to some Child's Sewing Machines, According to the Reference)
According to the provided reference, some needle clamps, especially those found on child's sewing machines, have a specific design to prevent loss of the clamp screw:
- Clamp Knob Location: The clamp knob is situated between the parallel needle and presser bars.
- Safety Mechanism: The clamp knob and screw extend from the needle bar in such a way that when retracted from the sewing needle, they strike the presser bar, thereby preventing the screw from being completely removed and potentially lost. This is a safety feature.
Importance of a Functional Needle Clamp
A properly functioning needle clamp is essential for:
- Consistent Stitch Quality: Prevents skipped stitches and uneven seams.
- Needle Stability: Reduces the risk of needle breakage.
- Safe Operation: Prevents the needle from becoming dislodged during use.
