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. |
