To enable the landing of a raw material jet to be easily and properly carried out in a former for papermaking such as a long-net paper machine, an on-top former, and a multilayer papermaking former.
This former for papermaking such as the long-net paper machine, the on-top former, and the multilayer papermaking former has a single wire part for dehydrating the paper raw material by at least one wire while conveying the paper raw material. The former has a dehydrating blade 21 slidably contacting with the wire, and the wire-contacting surface 21b of the dehydrating blade 21 is formed into a convex shape bent in the traveling direction of the wire. The midstream and downstream parts except the upstream part of the wire-sliding surface 21b have water-discharging opening 21 for discharging the water content dehydrated from the wire side.
