Flexible head platform of canvas or draper with double swather and attaching device

A feeding device for a flexible canvas or draper harvester comprising:

• an upper beam (8) adapted to be placed on an open section of a chassis, the upper beam (8) is linked to a lower front beam (10) and joined by side covers (11) and forming a frame;
• a first and a second lateral stud supports (12), the first and the second lateral stud supports having an L-shape;
• a central lower beam (9) placed in parallel and under the upper beam (8);
• a first and second central stud supports (13) connected to the upper beam (8) and the lower front beam (10), the first and the second central stud supports (13) having an L-shape with a short side, a long side connecting to the short side on a connecting point, each one of central stud supports (13) is connected on the short side of the L-shape to the upper beam (8), on the long side of the L-shape to the lower front beam (10), on the connection point of the L-shape to the central lower beam (9), and middle section of the long side of the L-shape to a second side to flexible body supports (14);
• a first flexible canvas (3) supported by the first lateral stud supports (12);
• a second flexible canvas (6) supported by the second lateral stud supports (12);
• a third and a fourth flexible canvas (4,5) supported by the central stud supports (13);
• wherein the first flexible canvas forms a first lateral body on the frame, the second flexible canvas forms a second lateral body on the frame, and the third and the fourth flexible canvas forms a central body,
• wherein a first space is formed between the first lateral body and the central body creating a first row and a second space is formed between the second lateral body and the central body creating a second row;
• wherein the first flexible canvas and the second flexible canvas have a length shorter than a length of the third or the fourth flexible canvas;
• wherein the lower front beam is free of additional elements;
• wherein a first fake structure is placed on the second space transforming the head into a one right row head reversing the traction of a right central canvas (5);
• and
• wherein a second fake structure placed on the first space transforming the head into a one left row head reversing the traction of a left central canvas (4).
