Abstract
A transition part is provided for a felt needle between the clamping part and the working part, which transition part is designed as elongated, narrow truncated cone. The length of this transition part is at least as long as twice the length of the working part. As a result, a very narrow transition region is formed, which has little tendency to pull out and accumulate fibers from the fibrous web. Should fiber deposits still form, these can be removed easily.
