Abstract
An undyed carpet web is pretreated by applying a liquid preparatory agent in a gap of an applicator. Subsequent to the application of the preparatory agent, the carpet web is detained in a dwell apparatus. The web is then suctioned off in a hydroextraction device and steamed in a steaming machine before the dyeing operation begins.
