Forming apparatus and method for forming a continuous tubular rod from a continuous tow material

A forming apparatus comprising:

• a transport path including a feed path for continuously feeding a continuous tow material along a transport direction of the transport path;
• a forming device connected to a downstream end of the feed path and adapted to form the continuous tow material into a continuous tubular rod, the forming device comprising:
• a tubular element adapted to allow the continuous tow material to pass through the tubular element to form the continuous tubular rod;
• a fluid compressor adapted to generate pressurized fluid, the fluid compressor being in fluid connection with the tubular element to provide pressurized fluid to the continuous tow material to heat or cool the continuous tow material;
• wherein the forming device further comprises several fluid conduits to provide pressurized fluid from the fluid compressor to several injection sites arranged along the transport path, wherein at least two fluid conduits of the several fluid conduits comprise a pressure control unit including a pressure sensor and a pressure influencer, and
• wherein the pressure control units are arranged in end sections of the at least two fluid conduits at the injection sites.
