You don't have to be an expert or a beginner to use your sewing machine. There are basic parts and uses you need to know. This includes the Needle plate, Thread take-up lever, and Bobbin winder. The presser foot lever should also be known.
Thread take-up lever
Basically, a Thread Take-Up Lever (TTL) for sewing machine is a device that prevents a thread from getting caught inside the sewing machine. It is usually located on the left-hand side of the machine. When you stop sewing, the take-up lever lifts the needle out of the fabric and releases the tension from the top and bottom threads. This is a good way to prevent a knotted or snags in the thread, and it can also help with rethreading.
The base portion, arm, and engaging piece are the three main components of a TTL. Each piece has a different function.
The base portion of the TTL is a semi-circular disc with three threaded holes. The arm is attached to the disc and extends from a chord of the semi-circle. It has an arcuate locking finger on its free end that extends forward and backward in opposite directions.
The thread take-up lever is not only a functional part of the machine, but also a good design idea. The spring prevents the upper thread from slipping in front of the needle. It also relieves strain when the thread is pulled by the hook. This is one of the most important functions of the TTL.
Other functions of the TTL include a mechanism to keep the loop in place while it rotates. The shuttle hook pulls the thread down and prevents it from coming off of the arm. To provide leverage, the clamp is a small metal screw that pushes the needle through the fabric.
The thread take-up lever is made of durable raw material, and it is designed to withstand external pressure. It can become stuck for many reasons so cleaning it is a good idea. If the screws become loose or jammed, it is a good idea also to change them. To remove knotted or entangled threads, clean the take-up lever between each use.
The TTL is a needle position gauge. This is the most important thing you need to remember. The lever is a good gauge of how high the needle needs to be in order to sew properly. The lever can be adjusted by turning a handlewheel.
Bobbin winder
Almost every sewing machine comes with a bobbin winder. It is an important part of stitching and a necessary tool. The bobbin is a storage device for the thread used in stitching. It is a circular spool which fits into the bobbin compartment on the sewing machine. The thread is then wound onto the spool.
Bobbins can be hand-wound or operator-wound. They can be made of nylon, monofilament, rayon or cotton. Because it evenly distributes the thread around the Bobbin, the bobbin winder plays an important role. It maintains the tension of the thread and prevents it from slipping and stretching.
Two to three bobbins are included with the sewing machine. The bobbins must be the same size and type. The thread can break or stretch if it is the wrong size or type.
The bobbin winder has a spool cap that holds the thread in place. This cap is usually situated on the right side of the machine. The thread is then wrapped around the empty bobbin. The thread is then looped around the thread guide to ensure that the thread is wound evenly.
The bobbin can be wound with a hand wheel or with a built-in bobbin winder. Instructions are included in the built-in winder that will show you how to use it. Some sewing machines are computerized. If the bobbin/bobbin winder does not work, you might need to change the needle.
To make sure that the thread is wound tightly, the bobbin should be four inches in length. Wrap the thread many times around bobbin's central column. It should be wound counterclockwise.
The lever should be raised so that the needle does not snag the fabric. This lever can protrude from front of machine or be hidden within the plastic casing. When the take-up lever is raised, the needle moves up and down in tandem with the lever. If the bobbin is full of thread, it should stop turning. If the bobbin is empty, it should not be tight.
Before you buy a bobbin winder, make sure it is the right size for your machine. The bobbin must not be too big or too small, as it could cause the bobbin winder to not work properly.
Needle plate
Special needle plates are available for several types of sewing machines. This feature allows you to sew straighter lines. Using the right plate can save you time and increase your machine's longevity.
One of the most important features of a needle plate is the size of the needle hole. If the hole is too small, your fabric could get sucked into the opening of the needle plate. A large opening, on the other hand, would allow your fabric to move back and forth and help you sew straighter seams.
A needle plate's support for your fabric is another important feature. Some sewing machines have vertical and horizontal stitch guides to help you align your fabric for the seam allowance. You can also control decorative stitches with a dial that adjusts the stitch length on some models.
Another feature of a needle plate is the insertion slit. This slit is formed in the lower section of the needle plate. This slit allows for the inserting of a thin 200-mm plate with high rigidity in the slit. This thin plate has been reinforced to avoid breakage due to the needle holes 110.
A conventional double-needle, post bed sewing machine has two needle holes. Each needle hole is in parallel and arranged in a cross shape. In later models, the spacing between the needle holes is narrow.
A special needle plate may also have grooves for markings to help you sew a straighter stitch. A vertical stitch guide is useful for lining up the fabric for the seam allowance and a horizontal stitch guide is the pivot point for the corners.
A thin plate made of heat-treated steel (SK-5) is inserted from the opposite end into the insertion slit on the needle plate. This makes it possible to separate the two needle holes without causing any damage to the needle or the machine. Preferably, the thin plate is of uniform thickness.
Another special needle plate is the throat plate. This component covers the bobbin and has slots that can accommodate the feed dog. The shield can be removed to clean the parts.
Presser foot lever
The typical presser foot levers have the handle at the distal end. They are used to lift the foot. They can move vertically, but they are not designed to interfere with the workpiece.
A presser foot lever can be a knob, a dial, a screw or a button. The computerized sewing machine system will recommend which presser foot is best for a particular stitch when selecting a stitch from a sewing machine. The presser foot can also be moved from the lowered to the active positions and from the retract position to active.
A typical presser foot lifting lever has a handle at its distal end, a shaft member near the base end, as well as a projection at its base end. The lever is attached to a laterally oriented arm. The shaft member supports the handle. A tapered pin holds the lever in place.
Presser foot lifting lever 8A has a handle position retainer to prevent interference with the workpiece. This retainer is located on handle and can be used to switch between active and retracted positions.
You can arrange the handle so that it projects into the recess. However, the lever should only be released if the handle is driven in enough. In this case, the presser foot can be replaced without causing damage to the machine.
Another feature of presser foot lifting lever 8A is a slide regulator 70 that allows the handle to be slid between the active and retracted positions. This feature can be provided with a hinge member that foldably attaches the handle to the lever body. You can also add a connecting portion 52 to connect the handle to your lever body.
The primary effects of this embodiment are similar to the first embodiment. However, the handle is retracted when the machine is not in use. Rotating the handle can allow you to retract the handle at a 90 degree angle. You can also rotate the handle to fit a shaft that points in the direction of the pin 30,
