Claim:
A forming member for controlling the volume of packages of pourable food products formed from a tube of packaging material and sealed at a number of sections of said tube crosswise to a first axis of the tube; said forming member comprising: a main wall adapted to cooperate cyclically with a first portion of said tube extending between two consecutive said sections; at least one flap extending alongside said wall; wherein said flap is movable, with respect to said wall, between a first position, in which it cooperates with a second portion of said tube, extending between the two consecutive said sections, to control the volume, between the two consecutive said sections, of said package being formed, and a second position, in which it is detached from the second portion, elastic means for loading said flap into one of said first position and said second position; an interaction surface connected operatively to said flap, and which engages a control member to move said flap into the other of said first position and said second position, in opposition to said elastic means; wherein said flap is hinged to said wall about a second axis; a body having said interaction surface and hinged to said wall about a third axis distinct from said second axis and which is offset with respect to said interaction surface; and a connecting member interposed between said body and said flap so that rotation of said body about said third axis rotates said flap about the second axis.
