Freehand quilting with BSR

Stitch: Straight stitch No. 1
Needle: size and type suitable for the fabric selected
Thread: monofilament or cotton
Feed dog: down
Presser foot: BSR foot No. 42

BSR (BERNINA Stitch Regulator) function

This function using the BSR presser foot allows for free-motion quilting (sewing) using the straight stitch and a pre-selected stitch length (up to 4mm). The BSR presser foot reacts to the movement of the fabric under the foot and controls the speed of the sewing computer up to the maximum possible speed.
The following applies: the faster the fabric is moved the higher the speed of the sewing computer. A regulated set stitch length is maintained within a certain speed, independent of the movement of the fabric. If the fabric is moved too fast an acoustic signal is heard, provided the beeper function has been previously activated. (see page 46).

! By activating the BSR function the sewing computer sews either continuously at a reduced motor speed (mode 1, standard) or on moving the fabric (mode 2). As long as the BSR presser foot is illuminated red, adjustments like threading and changing the needle, for example must not be carried out. The sewing computer is still in BSR mode and the needle will engage while fabric is moved unintentionally!
Without fabric feed the BSR mode is turned off after approx. 7 seconds and the red light goes off.
Please refer to the Safety Instructions!

BSR function can be sewn in 2 separate modes of operation

BSR 1

• BSR mode 1 is the active standard
• on pressing the foot control or the Start-/Stop button, the needle starts to move continuously
• moving the fabric under the foot will engage the sewing computer to accelerate
• through the continuous needle movement securing in the same position is possible without pressing an additional button

BSR 2

• press external button No. 2 of the stitch selection (see page 29) to engage BSR mode 2
• the sewing computer only starts if the foot control or Start-/Stop button is pressed and the fabric moved simultaneously
• the movement of the fabric determines the sewing speed
• for securing, the «Securing function» button must be pressed
• press external button No. 1 of the stitch selection to engage BSR mode 1

For an even sewing start (one single stitch) the foot control must be pressed and the fabric moved simultaneously. This also applies for sewing points and straight stitching within a round form.
When resuming work with the BSR presser foot after exiting the function, the BSR mode that was active at the time of exiting the BSR function will be activated, even if the sewing computer was turned off in the meantime.

48 Buttonholes

Buttonholes - Important information

aurora 430 / 440 QE

Thread tension

• thread the bobbin thread through the finger of the bobbin case = the bobbin tension is a little tighter
• this gives the beads on the right side of the fabric a slightly rounded appearance
• the buttonhole looks more attractive
• gimp reinforces buttonholes and enhances their appearance
• sew both beads at the same speed

aurora 450

Thread tension

• set upper thread tension to 2.5 (Buttonhole symbol)
• the bobbin tension is a little tighter which gives the beads on the right side of the fabric a slightly rounded appearance
• the buttonhole looks more attractive
• gimp reinforces buttonholes and enhances their appearance
• sew both beads at the same speed

Marking buttonhole

Manual buttonhole

• mark the buttonhole length in the desired position
• use Buttonhole foot No. 3C, 3 (optional accessory)

Automatic buttonhole

• mark the length of just one buttonhole
• after sewing the first buttonhole, the length for all subsequent buttonholes is automatically programmed
• mark only the beginning of all subsequent buttonholes
• use Automatic buttonhole foot No. 3A

Using the compensation plate (in some countries only available as optional accessory) is recommended when sewing buttonholes in difficult fabrics. It can be used with the Automatic buttonhole foot No. 3A or the buttonhole foot No. 3B.

Keyhole buttonhole

• mark the bead length only
• the correct length eye will be added when the buttonhole is sewn

Bulky buttons

• with bulky buttons (roll crown, bulge-rimmed etc.) add approx. 3-5mm to the buttonhole length (depending on the size and bulk of the button)

Test sewing

• always sew a test sample on the fabric with stabilizer you intend to use
• select the buttonhole type you intend to use
• sew the buttonhole in the same direction on the fabric (with or against the grain)
• cut the buttonhole open
• push the button through
• adjust the buttonhole length if necessary

To adjust the bead width:

• alter the stitch width

Stitch length adjustments:

• Stitch length adjustments affect both buttonhole beads (spacing between the stitches)
• reprogram the buttonhole length after changing the stitch length

If a buttonhole is to be sewn at right angles to a seam, we recommend the use of the height compensating plates for buttonholes (available as optional accessory). Place the plates from the back between fabric and bottom of slide foot up to the thick part of the fabric and push to front.

Buttonholes 49
