Fixing type is independent of device type. The bead is always dropped in the same way. Fixing stitches control bead orientation. However, different machines and dispensers have their own production requirements and idiosyncrasies.
Bead production is more exacting than sequin production. While sequin devices used to have similar issues, they have matured to the point where they can manage all kinds of fixing types at high speed. Moreover, sequin materials are more forgiving. Needle penetrations do not generally cause serious problems. The minimum commercial operating speed for bead production is 800 rpm or higher. Typical problems which can occur at high speed:
3Beads are missed
3Beads are smashed
3Needles are broken.
You may need to modify or ‘tweak’ predefined fixing types provided by the software in order to run reliably at high speed. This will involve testing on the machine. While fixing stitches in EmbroideryStudio automatically adapt to bead size, each bead type will need to be tested separately. Generally speaking, bead production can be stabilized when running machines at low speed, say, 600 rpm. This is suitable for testing.
A typical scenario might be:
3Develop a bead embroidery design.
3Carry out a sampling test at low speed.
3Test at production speed in order to calculate costs.
3Assess whether bead fixing meets high speed requirements – e.g. beads are missed or smashed.
3Adjust bead fixings and test again.
Options available in EmbroideryStudio for bead designers are:
3Modify or ‘tweak’ fixing stitches by means of object properties. This may involve:
3Trying out different fixing stitch types
3Testing automatic as well as fixed spacings
3Modifying margin settings.
3Edit bead fixings with the Bead Edit tool.
3Digitize bead drops with the Manual Bead tool.
3Insert bead drops with the Insert Function capability.
3Create your own bead fixings and save them as custom motifs.
