  • Patent number: 11358397
    Abstract: A digital printing machine comprises a cylindrical drum assembly on the rigid printing framework. A cylindrical drum moves along and rotates about its central cylindrical axis and a stationary printing head with multiple nozzles placed proximately above the circumference of the cylindrical drum. The combined linear and rotational movements of the cylindrical drum enable the printing head to create a smooth helical printing trajectory on the flexible fabrics. The cylindrical drum of the digital printing machine also works as a working drum to hold a piece of flexible textile to be printed. A double-side printing mechanism allows the digital printing machine to automatically carry out the second side printing.
