摘要： Process and apparatus are disclosed for the printing of textile bands, such as sponge-cloths with contiguous ends connected to each other by transversal selvedges, on a flat-screen printing machine with an endless carrying belt and printing units, said process consisting:in arranging between two consecutive sponge-cloths a reference sign to be read by at least one sensor;in adjusting the advancing of the carrying belt to a repeat equal to the nominal length of the sponge-cloths, and by converting said advance to a number of electrical impulses to be sent to a programmer-computer;in arranging the printing units at a distance equal to two times said repeat, centering the sponge-cloth manually by conventional means;in positioning said sensor at a distance from the first printing unit, equal to at least one repeat; andin shifting said printing units proportionally to variations in lengths of each sponge-cloth, with respect to the nominal value, by interlocking said displacements with the programmer-computer, actuated by said sensor which read the actual lengths of each sponge-cloth, said displacements of the various printing units and their actuation to print being automatically controlled and actuated by the programmer-computer, which follows the advance of the sponge-cloth step-by-step so as to obtain, in the case of sponge-cloths longer or shorter than the nominal ones, a corresponding displacement of the printing unit along the machine, and the printing of a sponge-cloth in a centered position.

摘要： A rotary cylindrical-screen printing apparatus for specularly printing equal patterns and/or colors onto the opposite faces of a fabric is disclosed, comprising two rotary screen printing machines, each equipped with electromechanical means for synchronizing the speed of the belt with the speed of the printing rollers, in which said machines are coupled by arranging one machine over the other, the fabric entering the underlying machine and thereafter entering the second upper machine which prints the opposite face of the fabric, the second machine comprising a transmission roller associated with its belt having a diameter equal to at least twice the diameter of the contiguous roller of the first machine, the apparatus comprising means for synchronizing the speeds of the printing rollers of two machines, including a transducer linked to the speed of the belt of a machine, whose outgoing frequency signal is sent to pilot the electrohydraulic motors controlling the printing rollers of both machines and means for synchronizing the speeds and phase of the two belts by linking the speed of the belt of one machine with the speed of the other belt through digital-analogue converters effecting a comparison between frequency signals picked up proportionally to the speeds of the two belts so as to emit a signal for the correction of speed and phase, said signal being sent to a means for driving the belt of the controlled machine.
