In order to boost production performance, manufacturers have sought to

develop technologies that enable the lap contact pressure to be

distributed over a larger surface area. Rieter have consequently developed

and patented a belt lapping system. Instead of the earlier linear load,

this enables lap guidance and pressure on the circumference of the lap to

be distributed over 180° at the start of the lap and 270° at the end of

the lap. Wrapping with a full lap, at the end of the lapping process,

resembles the Greek letter Omega.
