Machine for the production of coupled pleated fabrics, suitable to produce, a coupled fabric or, as an alternative, a reinforced coupled fabric, said coupled fabric consisting of a first fabric and a second fabric, both pleated, irreversibly engaged to each other at the fold points of said pleats; said reinforced coupled fabric consisting of said first fabric and said second fabric, both pleated, irreversibly engaged to each other at the fold points of said pleats and a plurality of stiffening slats, engaged in some pleats of said first fabric, said machine being characterised in that it comprises at least: - one first feed plane surface of said first pleated fabric towards a first roller; - one second feed plane surface of said second pleated fabric towards a second roller; - a feed loader of said stiffening slats, arranged in the vicinity of said second roller, at the output direction of the fabric from said roller; - said first roller provided with a central motor and with a toothed outer surface so that the pleats of said first fabric coincide with the teeth of said outer surface; - a glue dispenser arranged downstream of said second feed plane surface of said second fabric, and, therefore, immediately upstream of said second roller; said glue dispenser being suitable to release a predetermined amount of glue at the pleats of said second fabric that is intended to be irreversibly bound to the pleats of said first fabric; - said second roller provided with a central motor and a toothed outer surface so that the pleats of said second fabric coincide with the teeth of said outer surface; said second roller being positioned below said first roller at a distance such to determine the contact between the fold points of said first fabric and the fold points of said second fabric and the irreversible engagement of the pleats previously coated with glue by means of said dispenser; - a first processing plane surface on which the coupled fabric is conveyed, produced by the union of said first fabric and of said second fabric by means of the pressure exerted by the two rollers (110- 130); said first processing plane surface comprising at least one area with drying means, dedicated to the drying of the glue used for the bond between said two fabrics (10- 20); - a second processing plane surface on which the coupled fabric in output from said rollers (110- 130) is conveyed in the case where a reinforced coupled fabric is to be produced; said second processing plane surface comprising at least a drying area with drying means dedicated to the drying of the glue responsible for the bond between said two fabrics (10- 20); - a robotic arm, arranged upstream of said second processing plane surface and downstream of said feed loader of said stiffening slats; said robotic arm being suitable to position, one by one, said stiffening slats at a plurality of pleats, equally spaced from each other, of said coupled fabric, making it a reinforced coupled fabric. - one first feed plane surface of said first pleated fabric towards a first roller;
