Take Our Quiz To Learn About Functions & Parts Of Sewing Machine

The stitch regulator is responsible for controlling the length of the stitch. It ensures that each stitch is of the desired length, resulting in a consistent and even seam. Without a stitch regulator, the length of the stitch may vary, leading to an uneven and messy stitch. Therefore, the stitch regulator plays a crucial role in achieving precise and professional sewing results.

The correct answer is "Thread tension regulator." The thread tension regulator is responsible for controlling the tightness or looseness of the thread while sewing. It ensures that the thread is properly balanced and prevents it from becoming too loose or too tight, which can affect the quality of the stitches. By adjusting the tension regulator, the user can achieve the desired tension for different types of fabrics and sewing techniques.

The correct answer is "Presser bar lifter." The presser bar lifter is a mechanism in a sewing machine that is responsible for lowering and raising the presser foot. The presser foot is an essential part of the sewing machine as it holds the fabric in place while stitching. By lowering the presser foot, it ensures that the fabric remains flat and stable during the sewing process. By raising the presser foot, it allows for easy insertion and removal of the fabric. Therefore, the presser bar lifter is the correct answer as it directly relates to the action of lowering and raising the presser foot.

The thread take up lever is responsible for moving the thread up and down with each stitch. It helps to regulate the tension and ensure smooth and even stitches. By moving the thread up and down, it allows for proper feeding of the thread through the machine and helps to create consistent and balanced stitches.

The correct answer is "Bobbin case or shuttle." The bobbin case or shuttle is a part of a sewing machine that holds the bobbin. It is responsible for feeding the thread from the bobbin to create stitches on the underside of the fabric. Without a bobbin case or shuttle, the sewing machine would not be able to properly form stitches. The other options listed, such as the bobbin and bobbin winder, are related to the bobbin but do not directly hold it. The bed is the flat surface of the sewing machine where the fabric is placed during sewing.

The correct answer is "Bobbin winder". The bobbin winder is the part of a sewing machine that winds the thread onto the bobbin. It is responsible for creating a neat and even thread tension on the bobbin, which is essential for smooth and accurate stitching. Without a functioning bobbin winder, it would be difficult to properly prepare the bobbin for sewing.

The spool pin is the correct answer because it is the part of a sewing machine that holds the spool of thread. The spool pin is usually located on the top of the machine and allows the thread to unwind smoothly as it is fed through the machine during sewing. Without the spool pin, the thread would not be able to be properly fed into the machine, causing issues with the stitching process.

The feed dog is a mechanism in a sewing machine that moves the fabric forward and backward while sewing. It consists of small metal teeth that grip the fabric and guide it through the machine, ensuring smooth and even stitching. The feed dog plays a crucial role in the sewing process by controlling the fabric's movement and preventing it from bunching or slipping. Without the feed dog, the fabric would not be properly fed through the machine, resulting in irregular stitches and an overall poor sewing experience.

The thread guide is responsible for keeping the thread in position while sewing. It helps to guide the thread from the spool to the needle, ensuring that it follows the correct path and doesn't get tangled or twisted. Without a thread guide, the thread may not be properly positioned, leading to stitching problems and uneven tension. Therefore, the thread guide is an essential component in maintaining the correct thread position during sewing.

To make the machine run, the hand wheel needs to be turned toward you. This action helps to engage the machine's mechanism and initiate the sewing process. By turning the hand wheel, you provide the initial power needed for the machine to start sewing. Therefore, the hand wheel is essential in operating the machine and getting it to run.

The needle bar is responsible for holding the needle and controlling its upward and downward motion. This motion allows the needle and thread to pass through the cloth, creating stitches. The needle bar plays a crucial role in the sewing process as it ensures that the needle is in the correct position to create accurate and consistent stitches.

The presser foot is a sewing machine attachment that holds the fabric in place while sewing. It applies pressure to the fabric, preventing it from shifting or bunching up during the sewing process. This ensures that the stitches are straight and even. The presser foot can be adjusted to accommodate different fabric thicknesses and sewing techniques. It is an essential part of the sewing machine that helps to create professional-looking and well-finished garments or projects.

The pitman rod connects the crank to the treadle. The crank is responsible for converting the rotary motion of the treadle into the reciprocating motion of the connecting rod. This reciprocating motion is then transferred to the presser foot, which is an essential component in a sewing machine. Therefore, the pitman rod plays a crucial role in transmitting the motion from the crank to the treadle and ultimately to the presser foot, allowing the sewing machine to function properly.

The belt shifter is the correct answer because it is responsible for guiding the belt to its place in the band wheel. It helps to position and secure the belt in the correct position, ensuring that it stays in place and functions properly. The other options listed (crank, slide plate) do not have this specific function of guiding the belt, making them incorrect choices.

The throat plate is the correct answer because it covers the feed dog and other parts underneath. The feed dog is a mechanism that moves the fabric forward during sewing, and it is located underneath the throat plate. The throat plate also helps to guide the fabric and keep it in place while sewing. Therefore, the throat plate plays an important role in the functioning of the sewing machine by covering and protecting the feed dog and other components beneath it.

The correct answer is "Bed" because the flat base of the head refers to the part of the sewing machine where the fabric rests while being sewn. The bed provides a stable and smooth surface for the fabric to move across, allowing for accurate and even stitching.

The correct answer is "Belt" because it is the only option that connects the upper and lower wheel. The belt is an essential component in many machines that require the transfer of power or motion between two wheels or pulleys. It is commonly used in sewing machines to connect the hand wheel (upper wheel) and the lower wheel, allowing the user to operate the machine by turning the hand wheel. The belt ensures the synchronized movement of the upper and lower parts of the machine, enabling the sewing process to take place smoothly.

The slide plate is the correct answer because it covers the part where the bobbin shuttle is placed. This plate is located on the sewing machine and can be moved to access the bobbin area. It provides a protective cover for the bobbin and shuttle mechanism, preventing dust and debris from entering and interfering with the sewing process.

The correct answer is "Bobbin". A bobbin is a small cylinder or spool that holds the lower thread in a sewing machine. It is placed on the spool pin and is essential for the proper functioning of the machine. The bobbin is responsible for creating the lower thread tension and is used in conjunction with the upper thread to form stitches. Without a bobbin, the sewing machine would not be able to stitch properly. Therefore, the bobbin is the correct answer in this context.

The band wheel is the correct answer because it is described as the "bigger wheel that moves with the hand wheel through their connecting belt." This suggests that the band wheel and hand wheel are connected by a belt, and the band wheel is larger in size. Therefore, the band wheel is the correct option.

The crank is a mechanical device that is used to convert rotary motion into reciprocating motion. In this context, it is likely that the crank is used to turn the band wheel. The band wheel is another mechanical component that is used in various machines, such as sawmills or industrial equipment. Therefore, it is reasonable to assume that the crank is responsible for turning the band wheel in order to initiate or control the machine's operation.
