  • a method for momentary compression of a continuous multi-segment rod by means of compressing rollers is known from the Polish patent application PL402777.
  • the problem to be solved by the present invention is to develop an improved apparatus and a method for compression of the filter material.
  • the substance of the invention is a method of pressing filter segments moving in a train of segments characterised in that the filter segments are pressed by means of a shoe, whereas between the undersurface of the shoe and the filter segments laid on a guiding wrapper, before gluing and covering a train of segments with the wrapper, compressed air is supplied by means of ducts.
  • the substance of the invention is a shoe for pressing segments of a continuous multi-segment rod characterised in that the undersurface for pressing the filter segments, laid on a guiding wrapper before gluing and covering a train of segments with the wrapper, is provided with a set of nozzles for blowing in compressed air supplied through ducts.
  • a shoe according to the invention is characterised in that the nozzles widen in the direction to the segments of a continuous multi-segment rod.

  • a shoe according to the invention is characterised in that the rows of nozzles are arranged symmetrically to the axis of symmetry of the undersurface.
  • a shoe according to the invention is characterised in that the rows of nozzles are arranged asymmetrically to the axis of symmetry of the undersurface.
  • a shoe according to the invention is characterised in that its undersurface is a cylindrical surface.
  • a shoe according to the invention is characterised in that the radius of the cylindrical surface is 1.5 to 10 times greater than the radius of the segments, preferably 2 to 5 times greater.
  • a shoe according to the invention is characterised in that the undersurface is a flat surface.
  • a shoe according to the invention is characterised in that the undersurface has grooves ( 18 ) distributing compressed air.
  • a shoe according to the invention is characterised by being attached at an angle to the axis of the segments, in particular at an angle between 0.7° and 2°.
  • a shoe according to the invention is characterised in that the ducts are situated in relation to the vertical direction at an angle in the range between 0° and 30°, preferably in the range between 10° and 20°.
  • a shoe according to the invention is characterised in that the undersurface is situated asymmetrically to the axis of the segments.

  • the dimension D can be similar to the dimension L or the nozzles 17 A can be joined with each other forming a duct used for pressing segments with compressed air.
  • the use of multiple nozzles allows maintaining the pressure caused by the action of compressed air at a principally constant level.
  • the surface 17 B of the nozzle, which enlarges the nozzle 17 A, can have a cylindrical or conical form.
  • FIG. 6 a shows a pressing undersurface 11 provided with nozzles 17 arranged in a single row along the axis of symmetry 11 X
