A system for in-line treatment of one or more threads for use with a thread consuming device is provided. The system includes a treatment unit having a plurality of nozzles being distributed in at least a first and a second dispensing zone, the dispensing zones being separated in a direction being perpendicular to the longitudinal direction of the at least one thread, said thread being in motion in use, each nozzle being configured to dispense one or more coating substances at least onto the at least one thread when activated, and a control unit being configured to control activation of each dispensing zone of nozzles independently. A method is further provided.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system includes a treatment unit including at least a first and a second print head each being configured to dispense one or more coating substances onto the at least one thread when activated; and a control unit configured to determine if a maintenance sequence is to be performed on at least the first print head, and if so schedule said maintenance sequence on at least the first print head. A method is further provided.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system comprises at least one treatment unit being configured to dispense one or more coating substances onto the at least one thread when activated and a thread speed sensor being driven by the motion of the at least one thread. A method is further provided.

A method for providing visual effects to a decorative thread pattern, is provided. The method includes determining an object to be produced as such decorative thread pattern, determining a thread arrangement comprising a plurality of consecutive thread portions, each thread portion having a thread portion direction, wherein the entire thread arrangement corresponds to said object to be produced, determining at least one visual effect of said object to be produced, said visual effect being associated with a set of thread portions of said thread arrangement and having a direction being different from at least one thread portion direction of the set of thread portions, and determining a colouring scheme for a specific thread such that the visual effect is obtained when production of the decorative thread pattern, using said thread according to said thread arrangement, is performed. A control unit is also provided.

A liquid discharge apparatus is to be coupled to a post-processing apparatus to perform post-processing using a linear medium such that the post-processing apparatus is disposed downstream from the liquid discharge apparatus in a conveyance direction of the linear medium. The liquid discharge apparatus includes a discharge head, a conveyance mechanism, a head driver, and control circuitry. The discharge head includes a nozzle to discharge droplets onto the linear medium to dye the linear medium. The conveyance mechanism conveys the linear medium in conjunction with the post-processing apparatus. The head driver drives the discharge head in conjunction with conveyance of the linear medium. The control circuitry controls the head driver and determines whether to execute maintenance of the discharge head based on a time required for the post-processing for each dyeing job.

A system and method of printing on a strand element with a printer head. The printer head includes a conduit and a cavity formed within the conduit, wherein the cavity is configured to receive the strand element and pass the strand element from a first end of the cavity to a second end of the cavity. The printer head also includes a first set of fluid nozzles formed on the conduit and positioned on a perimeter of the cavity around a first target location within the cavity, wherein each of the fluid nozzles in the first set is positioned to aim at the first target location, and the first target location corresponds to a location of a first segment of the strand element when the strand element is positioned within the cavity.
