Abstract
A microcreping process is improved by using a razor sharp retarder blade positioned such that its razor edge is overlapped by either the primary blade or a back-up blade, whichever extends the furthest downstream. Preferably, pressure is applied to the primary blade through one or more back-up blades arranged in a stepwise configuration.
