Abstract
A method for improving the rush transfer of a web, such as a tissue web, is disclosed. The method provides for greater angles of convergence and divergence of the carrier fabric and the transfer fabric at the point of transfer by deflecting the carrier fabric toward the transfer fabric using a deflection element, such as a roll, positioned opposite the vacuum transfer head. The greater angles of convergence and divergence minimize the potential for undesirable macrofolds being formed in the web during transfer.
Claims30
A method for transferring a cellulosic web supported by a carrier fabric to a slower-moving transfer fabric wherein the transfer fabric and the carrier fabric converge and diverge as the transfer fabric passes over a vacuum shoe having a vacuum slot and the carrier fabric passes over a deflection element, wherein the vacuum shoe deflects the transfer fabric towards the carrier fabric and the deflection element deflects the carrier fabric towards the vacuum shoe such that the web transfers to the transfer fabric as the web passes over the vacuum slot.
A method for transferring a cellulosic web supported by a carrier fabric to a slower-moving transfer fabric wherein the transfer fabric and the carrier fabric converge and diverge as the transfer fabric passes over a shoe having an opening therein and the carrier fabric passes over a deflection element having at least one orifice therein for discharging pressurized gas, said orifice communicating pneumatically with a pressurized gas source, wherein the shoe deflects the transfer fabric toward the carrier fabric and the deflection element deflects the carrier fabric toward the shoe, and gas discharging from said orifice acts to assist the transfer of the web to the transfer fabric.
