Concentrating method and means therefor

Treatment of wood chips

A tampon comprises a compacted tampon blank, which in turn is formed by winding a liquid-permeable strip and a string of absorbent material placed thereon to a roll and inserting strip-parts which project from the sides of the string, inwardly of the innermost turn or winding of the roll. In the process of manufacturing the tampon, the strip carrying the string can be wound around a first, tubular mandrel, and one strip-part can be inserted into the mandrel through one open mandrel-end located adjacent the inner edge of the strip-part. A second tubular mandrel is then inserted through the open end of the first mandrel and the first mandrel then withdrawn. With the second mandrel surrounded by the first, inserted strip-part and located with an open end adjacent the inner edge of the other strip-part, the other strip-part is inserted into the second mandrel, which is then withdrawn from the thus formed tampon blank, which is thereafter compacted or compressed.
