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.

A system (10) for in-line treatment of thread (20) for use with a thread consuming device (15) is provided. The system comprises a treatment unit (100) comprising at least one discharge device (150) being configured to dispense one or more coating substances onto the at least one thread (20) when activated; and a drive unit (32) being configured to move said at least one discharge device (150) between an idle position (42) and an operational position (41) being arranged along an axis of movement (A).

A system for in-line treatment of at least one thread is provided. The system is configured to be used with a thread consuming device and comprises a treatment unit having a plurality of nozzles arranged at different positions relative the at least one thread, said at least one thread being in motion in use, each nozzle being configured to dispense one or more coating substances onto the at least one thread when activated; and at least one thread engagement device configured to rotate the at least one thread along its longitudinal axis as the at least one thread moves through said treatment unit.

A thread printing system includes a source spool containing thread. The system also includes various print heads, each of which is fluidly connected to an ink tank. The print heads are positioned to direct and apply ink to a segment of the thread as the thread travels along a transport path along from the source spool. The system also includes a fuser having one or more print rollers that are connected to a heating element. The fuser receives the dyed thread and fuses the ink to the thread. The system may include a controller that is configured to apply ink of different colors to different segments of the thread.

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 set of nozzles formed on the conduit and positioned on a perimeter of the cavity around a first target location within the cavity, wherein at least one of the nozzles is a fluid nozzle configured to dispense a fluid, and at least one of the nozzles is a vacuum nozzle configured to apply a vacuum force on the cavity.

This weaving machine (2) is for simultaneously weaving top and bottom pile fabrics (F2, F4) presenting some pile patterns (P2, P2′, P4) and including tufts, made from warp yarns (24), binding warp yarns (14, 16) and inwoven weft yarns. This machine includes a pile warp yarns feeding unit (20), a binding warp yarns feeding unit (18), a shedding unit (6) and a weft insertion unit (8) for inserting the weft yarns in the shed. The machine also includes a beating-up mechanism (32), a take up system (70), a drawing-in unit (26), and a control unit (80). A treatment unit (90) is located, along a path of the pile warp yarns (24), between the pile warp yarns feeding unit (20) and the shedding unit (6), for applying different segments of treatment on at least some of the pile warp yarns (24).

A system for treatment of thread includes a weft thread printer having an intake positioned to receive a weft thread from a source, as well as an encoder that is configured to detect a length of the weft thread as the weft thread moves through the weft thread printer along a travel path. The system also includes a printhead positioned to apply coatings of a plurality of colors to the weft thread and yield a treated weft thread, as well as an outlet positioned to pass the treated weft thread to a loom.
