Adjusting Needle Brushes
The needle brushes must be adjusted when errors occur during stitch formation, e.g. drop stitches.
The needle brushes open the needle latches for inserting the thread. They are swivel-mounted so, that they are always inclined in the direction of travel of the carriage assembly.
The needle brushes are correctly adjusted when
- the brushes project an equal distance over both sides of the holder The markings on the brush are visible on both sides.
- the canted surfaces (3) opposite each other
- the brushes do not touch the needle hooks of the fully raised needles (DJ). The distance (4) is to be 0.5 mm to 1 mm.
