The invention relates to an assembly consisting of base tracks inside which a drag chain moves and in the bottom part of which the tracks for the sheets, in the form of a "J", are attached along the entire length thereof, inside of which tracks the bearings of the guide shoes, which serve to guide the sheets as they move and fold, are housed. Drag tracks are provided on the upper part of the body of the base track, forming a °°C" inside which a drag piece, on which the drag shaft is threaded, is housed and moves, a tube soldered to the drag track being attached to the upper part of said drag shaft, providing the seat for angle as a drip stopper and some neoprene bands. The lateral part of the track serves as a wall for channeling water. |
