COMMON FAULTS AND REMEDIES Complete Tasks 2 on your worksheet.

COMMON FAULTS AND REMEDIES Loops on wrong side of stitching: The upper tension is too loose or machine is not correctly threaded. Check threading and tighten upper tension. Loops on right side of stitching: The upper tension is too tight or machine is not correctly threaded. Check threading and loosen upper tension. Missed stitches: Change the needle as it could be bent, blunt, incorrectly fixed or is not the correct size for fabric. Check threading.

COMMON FAULTS AND REMEDIES Thread breaking: The tension disk is set too tight so it needs to be loosened or the needle is bent or is too fine so it needs to be changed. Puckered seams: The tension is set too tight so it needs to be loosened. Stitches not interlocking: Needle may be inserted backwards. Insert needle properly, check that it is the right size and is not bent and check that the machine is correctly threaded.

COMMON FAULTS AND REMEDIES Broken needle: Needle could be damaged or inserted incorrectly. Insert properly, check that it is the right size and is not bent and check that the machine is threaded correctly. Material not moving under presser foot: The fabric may be too thick (or too many layers of fabric). Remove fabric and check there is no thread jammed at the bobbin compartment, throat plate or anywhere else in the machine.

SEWING MACHINE NEEDLES There are different types of sewing machine needles which are changed according to the type of fabric being used. Eg: • Regular point needles: for woven fabrics • Ball point needles: for knit fabrics • Chisel point needles: for leather (punch through fabric) • Denim needles: for thicker fabrics. • Twin/Triple needles: two/three needles joined in a row which stitch at the same time- very decorative. There also different needle sizes (according to thickness of fabric):

PREPARING THE SEWING MACHINE FOR SEWING

PREPARING THE SEWING MACHINE FOR SEWING 1. Prepare the basic parts needed to sew: • • Choose the right size and type of needle according to the fabric and insert it in the needle clamp with the flat side towards the back. Attach the appropriate sewing machine foot. Wind the bobbin (see Youtube video on next slide). Insert the bobbin in the bobbin case (see Youtube video on next slide).
