Abstract: There is described a papermaking machine of the type wherein a web of lignocellulosic fibers is formed, and wherein the formed web is transferred to a dewatering and imprinting felt, said felt and web then passing through a nip formed by a pressure roll and a drying cylinder so as to deposit the web on the drying cylinder, said web having a dryness level between 7 percent and 35 percent as it enters said nip, characterized by the felt having imprinting yarn strands forming knuckles adjacent to the web contacting surface of the felt, the imprinting yarn strands having a spacing of about 6 to about 25 per 0.0254 meters but not significantly exceeding the average fiber length, the felt having a web facing greater than about 153 grams per square meter, and the felt having a ratio of face web in grams per square meter to the diameter in meters of the imprinting yarn strands adjacent to the web contacting side of the felt of from about 60,000 to about 600,000 wereby the web is differentially pressed onto the dryer surface. The machine of this invention is especially useful in manufacturing sanitary paper tissue and towel products.

Abstract translation: 描述了一种其中形成木质纤维素纤维网的类型的造纸机，并且其中所形成的幅材被转移到脱水和压印毡上，然后所述毡和纸幅经过由压力辊和干燥筒形成的辊隙 以便将纤维网沉积在干燥筒上，所述纤维网在进入所述辊隙时具有7％至35％之间的干燥度，其特征在于，毡具有形成与毡的纸幅接触表面相邻的转向节的压印纱线， 每0.0254米具有约6至约25个间隔但不显着超过平均纤维长度的印花纱线，所述毡具有面向大于约153克/平方米的幅材，并且所述毛毯具有的面纤维的比例 平方米以约60,000至约600,000的纤维网接触侧邻近的压印纱线的直径（以米为单位）通过网而差异地按压 在干燥器表面上。 本发明的机器在制造卫生纸巾和毛巾产品中特别有用。
