Treating carpets in wet bath without permanent creasing - by passing them in the bath over folders inducing transverse random folds over part of carpet width

摘要

Carpets joined into endless webs are repeatedly passed through a wet treatment bath in transversely folded state such that the transverse folds extend only partially across the width of the treated carpets. Permanent creasing is prevented. Pref. the carpet is fed over a former which induces relative movement to the carpets such that the folds extend obliquely in the plane of the carpets in one or the other direction, the folds which extend only partially across the width of the carpets intersect one another in random manner and the folds have a reduced height at their pts. of intersection.
