Needle And Thread Matching; Thread Selection - Bernina L460 Instruction Manual

Needle and thread matching

Thread selection

Operating Instructions
The fabric used determines the thread weight and accordingly the needle size. When sew-
ing, the thread is fed through the long groove in the needle. If the needle is too fine, the
thread does not fit into the groove and stitches will be skipped. Needles No. 70 - 90 on the
overlocker.
Sewing and special overlock threads are manufactured in a wide variety of types, weights
and combination of fibres. It is worth investing in good quality threads for perfect sewing
results. Decorative threads specially made for overlockers (available on cones or on
spools) can be purchased almost everywhere. If special threads are used on the over-
locker, it is recommended to consider following guidelines:
⦁ Purchase threads on cones or spools which are produced exclusively for overlocker.
⦁
Always use normal spools in combination with the spool caps (in accessory box).
⦁
Only use decorative threads in the loopers. The thread has to run easily and smoothly
through the thread guide and the the looper eye .
̶ The thicker the thread, the longer the stitch length (3-4).
̶ The thicker the thread, the looser the tensions.
⦁ It is recommended to start sewing at minimum speed.
⦁ Sew slowly when using decorative threads.
⦁ Pull the thread chain gently to the back when starting to sew. Always test sew decora-
tive threads before starting to sew the project. BERNINA recommends using high-
quality threads such as Mettler Seracor®, Serafloc®, Seralene®,Poly Sheen® and
Isacord.
Keep in mind that the looper threads will use about 6-10 times the amount of
thread used in the needles.
