Abstract
A process and an apparatus for the continuous and controlled application of liquor on an absorptive, compressible material web such as textile webs, warp yarn layers or vleeces. One or more liquors are applied in amounts being comprised between the values of water retention capacity and saturation. The liquor containing web is passed through an equalizing device wherein the web is drawn through an equalizing nip or slit whose thickness is adjustable and smaller than the thickness of the incoming, liquor containing material web. The equalizing may be effected in the nip of two rollers. The liquor concentration in the web before and after the equalizing is statistically the same.
Claims12
An apparatus for the continuous and controlled treatment of an absorptive and compressible material web, said apparatus comprising:
- means for advancing the web along a path;
- an applicator device for applying liquor to the web while the web is advancing along said path;
- two solid surfaces on said path and downstream from said applicator device, said solid surfaces forming a nip for equalizing the distribution of liquor applied to the web by redistributing liquor from regions of the web which contain relatively high amounts of liquor to regions of the web which contain relatively low amounts of liquor, without squeezing liquor out of the web;
- and
- thickness adjusting means for adjusting and controlling the thickness of said nip by moving one of said solid surfaces with respect to the other.
