SINGER XL100 Quantum - Manual (Page 21)

Automatic Computer Controlled Thread Metering (tension) System
Insteadof a mechanical tension system, which controls thread by squeezing it between 2 discs, the XL-100 controls thread by
computer. An automatic computer controlled thread metering system delivers the precise amount of thread for each needle
penetration to create the optimal appearance of each stitch. This makes possible, perfectly balanced straight stitch, plus no
pucker blind hemming, two color patterns without changing thread, multicolored embroidery without changing bobbin thread, and
decorative top-stitching and cross stitching that simulate hand sewn. An override control allows individual modification for
specialized effects.
Examples of Automatic Thread Metering:
Upper thread
Straight stitch: Upper and
bobbin thread join in middle.
Upper thread Upper thread
Bobbin thread Fabric
(Wrong side)
Embroidery and decorative topstitch
patterns: Upper and bobbin thread
join on wrong side of fabric to
optimize top side appearance.

Bobbin thread
Two-color patterns: Upper and
bobbin thread join on right side
of fabric.
