Should the needle be up or down when you start sewing?
Should the needle be up or down when you start sewing?
Your sewing machine works by continuously moving the needle in an up and down motion, piercing the fabric. The top thread is locked in with the bobbin thread to create the stitches. Before you start any new line of stitching, make sure the needle is in the UP, or the highest, position.
Is my sewing machine needle too long?
If the needle length is too long, the point of the needle may still be in the fabric when the feed dogs begin moving the fabric. This can cause missed stitches, puckering and needle damage. A longer needle may also hit a part of the machine on its downward stroke.
How do you know what size needle to use?
Most needle companies show both sizes on the package. A good rule of thumb to keep in mind: the lighter the fabric the smaller the needle size and the heavier the fabric the larger the needle size. Many times the thread you will be using for your sewing project will also determine the type of needle you choose.
When you are finished sewing a seam where should the take up lever be?
Answer: Every sewing machine has a thread take-up lever. It is the arm carrying the thread at the top of the machine that moves up and down in a narrow, shaftlike opening. It’s very important that this arm always be left in its highest position when you have finished sewing a seam.
What does a needle positioner do?
Our Synchronizer Needle Position Control allows you to stop the needle in various set positions. This synchronizer is ideal for turning corner stitching or any other applications that require up or down needle positioning.
Do servo motors have encoders?
Mechanism. A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. More sophisticated servomotors use optical rotary encoders to measure the speed of the output shaft and a variable-speed drive to control the motor speed.
