A papermaking machine for producing multi-ply paper includes a number of screening sections disposed one above another, each arranged to produce a ply, each section having a stock inlet, and adjacent sections having wires which run together over a zone for uniting plies, at least two adjacent sections being staggered lengthwise of the machines so as to overlap for only part of their length remote from the stock inlets, and wherein at least the top one of the overlapping sections is supported by its own floor, and this section overhangs beyond its floor. The sections may be of the Fourdrinier type, and have overhang of 1/6-1/2 of the total length. Support elements for the overhanging section(s) may be provided to support the overhanging part on the machine frame of the section below. These supports may be removable for wire-changing. Each section may be conventionally cantilevered to facilitate wire-changing. Suction means are provided in the zone of running together to entrain the formed web with the required wire.
