Abstract

Process for the production of longitudinally extending pressed absorption bodies from an endless nonwoven web which is transported continuously in the direction of advance by pressing elements drivable in the direction of rotation and belonging to a pressing station and which is provided simultaneously with at least three longitudinal grooves arranged at equal angular spacings, whereupon the nonwoven web forming a pressed strand is subdivided into portions of specific length, characterized in that the nonwoven web (140) is driven in the conveying direction (x), by means of the pressing elements drivable in the direction of rotation, in a plane extending transversely relative to its longitudinal direction and simultaneously is pressed radially at least to the final cross section of a pressed strand (240) and, at the same time, is provided with longitudinal grooves (131).
