The Roller Bundle is locked into parallel rotation within the curves of a balanced row of continuous belting. This interconnecting of the rollers creates a stable, self supporting, low friction scrolling assembly.

The unique relationship between the belts and rollers defines the movement principle, introducing a previously unknown geometry expressed in the method of the belt weave.

Before Scroller-Mechanics, at least one pulley in any system had LESS THAN 180 degree WRAP and therefore slipped.

Belts wrap scrollers more than halfway around their circumference (3 at a time), providing a high degree of surface to surface contact. Fig. 01

Rows of Belts weave around and between rollers, moving in the same direction and at the same surface speed as the rollers that they wrap. Link: Precision

C-Shaped belts are offset from belt-to-belt in an alternating pattern, locking the rollers snugly in parallel. This 'tensioning on a common shaft' creates balanced tug-points that pull orbit-rollers inward while holding them apart from each other.
