The purpose of the invention is to improve the quality of products by ensuring the accuracy of adjusting their length. The multi-extrusion head comprises a housing in which the working and feed channels are made. The working channel is installed with the formation of two separate cavities and with the possibility of a flow divider along the axis. The head contains forming elements made in the form of plates, installed with the formation of slot channels and interconnected by means of drags. The plates are mounted with the possibility of their joint movement along the axis of the working channel to the alternate overlapping of its outlet openings. Stops coaxially with the flow divider are mounted with stops placed in the working channel with the possibility of axial movement along the axis of the working channel and interacting with the flow divider in its extreme positions. During operation, the polymer melt flows through the feed channel into the working channel. Some of the slotted channels are blocked, while others are open. Under the pressure of the melt, the divider moves until it touches one of the stops. At the same time, a sheet of strictly fixed length is squeezed out through open slotted channels. Thereafter, the overlap of the slotted channels is changed, and the cycle is repeated. 2 Il. S (l
