  • Page 32: 5-12) Needle-Hook Timing Control

    5-12) NEEDLE-HOOK TIMING CONTROL 1) Needle ① It is very important to select the right needle for the type of thread and fabric used. ② Inappropriate needle may cause bad embroidery, thread breaks, skipped stitches, etc. ③ For normal embroidery, use a DB×K5 needle. [CAUTION] DB K5 needle has an eye twice larger than that of DB1 (used for normal sewing).
  • Page 33 ② When inserting the needle, make sure that the groove Needle insert hole of the needle is facing front. Shaft of the needle should be inserted completely into the needle bar. Front groove of the needle groove [Fig.5-19] [CAUTION 1] For special threads such as artificial silk, turn the needle slightly to the right to prevent thread breaks (see [Fig.5-20]).

  • Page 35 [CAUTION] Functions by Needle Shape ① Size of the hole and groove differs by needle. • Front groove: protects the thread from the heat of the Front groove sewing friction (which may cause thread breaks). • Back groove: helps regulate the hook timing and prevents looping.
  • Page 36 5) Relationship between the Take-up Lever and the Hook Hook point timing is directly related to thread tension and thread breaks. The following pictures show the location of hook when the take-up lever starts to move up from the lower dead stop (main shaft rotation angle: 292°). FAST HOOK TIMING Groove of the hook is in the (A) range.
