Abstract: A widening device for increasing the width of a moving web of material comprises a rotatable profiled roller, the outer surface of which defines a plurality of radial projections and recesses distributed along the length of the roller and first and second co-operating rollers rotatable at the same speed as the profiled roller. The first and second co-operating rollers define projections and recesses complementary to those of profiled roller and define first and second treatment nips which serve to increase the width of a web of material passed therethrough. The projections on the co-operating roller defining the second treatment nip extend more deeply into the recesses of the profiled roller than do the projections on the co-operating roller which defines the first treatment nip so that the web of material is stretched gradually over two stages with the stretching effect being uniform across the entire width of the web.

Abstract: A device for applying a treatment liquid to a moving web of material such as a textile web includes a drum that is rotatable around a horizontal axis. At least one guide roller is provided for guiding the fabric web such that the web wraps at least partially around the drum beginning at a side of the drum at which the web is disposed tangentially thereto and continuing around a bottom portion of the drum. A trailing, continuous band is also provided which is closed in a liquid-tight manner and circulates in a plane that is perpendicular to the axis of the drum. The band has an outer circumferential surface that fits closely on the fabric web at a location in which the web contacts the drum. The circumferential surface of the band and drum define a nip therebetween. The band seals off the nip at its bottom. The band has web segments forming lateral sealing elements which extend from the edges of the band to project outwardly. The segments have a side abutting a contact surface formed at the rim of the drum.
