Abstract:
1. A process for making a tissue web comprising: forming a wet tissue web by depositing an aqueous suspension of papermaking fibers onto a forming fabric; partially dewatering the wet tissue web; conveying the tissue web from a transfer fabric to a throughdrying fabric, the tissue web being contacted by a fluid stream that pushes the web from the transfer fabric to the throughdrying fabric as the web is being conveyed in between the two fabrics around a transfer roll; drying the tissue web in a throughdryer as the web is conveyed on the throughdrying fabric, the throughdryer including a drying cylinder, the throughdrying fabric and the tissue web being wrapped around the drying cylinder at least 300°, the throughdrying fabric forming an endless loop; wherein the transfer roll is positioned outside the endless loop of the throughdrying fabric, the transfer fabric and the throughdrying fabric being wrapped around the transfer roll in an overlapping relationship, the transfer roll including a pressurized zone configured to emit a gaseous stream for facilitating transfer of a paper web from the transfer fabric to the throughdrying fabric, adjacent to the transfer roll, the pressurized zone located on the transfer roll being configured to emit the gaseous stream at a pressure of from about 4 inches Hg to about 60 inches Hg; and winding the dried web onto a parent roll, wherein the tissue web does not contact any paper machine rolls during the process prior to the step of winding the dried web onto a parent roll.
