<p>Conveying device to be mounted on a sewing machine comprising a plate to be constrained to a base of the sewing machine, a conveyor belt mounted on two rollers constrained to a supporting structure so as to rotate, the supporting structure being coupled with the sewing machine, so that the conveyor belt is adjacent to the plate, and motor means connected with the conveyor belt and suited to put said belt in motion so that a cloth arranged between the plate and the conveyor belt translates when the conveyor belt is put in motion. The conveying device comprises at least a pressing element actuated by a piston of a cylinder which comprises elastic means and is constrained to the supporting structure of the conveyor belt, said cylinder being connected with a pressure control system. The pressure control system adjusts the pressure acting on the cloth to be conveyed since the elastic means are adjustable through the same system and the pressing element is in contact with the portion of the plate and/or belt.</p> |
