Process and apparatus for needling a non-woven strip to a revolving endless carrier web |
摘要 |
In a process in which a non-woven strip is needled to a revolving endless carrier web, adjacent convolutions of the non-woven strip should exactly adjoin each other. For that purpose each convolution of the non-woven strip is initially needled to the carrier web with the exception of a marginal portion, which constitutes a free longitudinal edge, and that marginal portion is needled after the position and direction of the free longitudinal edge have been detected.
