Soft, absorbent paper webs and processes for making them. In the process, an aqueous dispersion of the papermaking fibers is formed into an embryonic web on a first foraminous member such as a Fourdinier wire. This embryonic web is associated with a second foraminous member known as a deflection member. The surface of the deflection member with which the embryonic web is associated has a macroscopic monoplanar, continuous, patterned network surface which defines within the deflection member a plurality of discrete, isolated deflection conduits. The papermaking fibers in the web are deflected into the deflection conduits and water is removed through the deflection conduits to form an intermediate web. Deflection begins no later than the time water removal through the deflection member begins. The intermediate web is dried and foreshortened as by creping. The paper web has a distinct continuous network region and a plurality of domes dispersed throughout the whole of the network region.

A process for making a strong, soft, absorbent, paper web comprising the steps of: (a) providing an aqueous dispersion of papermaking fibers; (b) forming an embryonic web of said papermaking fibers from said dispersion on a first foraminous member; (c) contacting said embryonic web with a second foraminous member having an embryonic web-contracting surface comprising a macroscopically monoplanar, patterned, continuous network surface defining within said second foraminous member a plurality of discrete, isolated, nonconnecting deflection conduits; said second foraminous member having a second surface; (d) deflecting at least a portion of said papermaking fibers in said embryonic web into said deflection conduits intermediate said embryonic web-contacting surface and said second surface and removing water from said embryonic web through said conduits and rearranging said papermaking fibers to form an intermediate web of said papermaking fibers under such conditions that said deflecting is initiated no later than the initiation of said water removal; (e) predrying said intermediate web in association with second foraminous member to a consistency of from about 25% to about 98% to form a predried web of papermaking fibers; (f) impressing said network surface into said predried web by interposing said predried web between said second foraminous member and an impression surface to form an imprinted web of papermaking fibers; and (g) drying said imprinted web.
