A method of coating threads using a printhead having rows of nozzles extending along a length of the printhead. The method includes the steps of: feeding the thread along a length of the printhead; and ejecting ink from the rows of nozzles towards the thread. Thread-coating modules and thread-coating systems make use of the method described.

An article of manufacture, comprising, an artifact formed from at least a portion of at least one continuous artifact fiber, the artifact fiber dyed by a first digitally controlled dyeing process to exhibit a visible first color section and a visible color gradient section transitioning from and visibly distinguishable from the first color section; and, a textile portion, comprising at least one dyed fiber that has been dyed by a second digitally controlled dyeing process; wherein said artifact fiber is dyed by the first dyeing process applying metadata, said metadata relating to at least said first color, and wherein said textile portion fiber is dyed at least said first color by the second dyeing process applying said metadata.

A liquid ejecting apparatus includes a plurality of ejection heads, each including a nozzle array in which a plurality of nozzles, each configured to eject a droplet, are arranged in an array; and an ejection receiver configured to receive the droplet from the plurality of ejection heads. A conveying direction in which an ejection target medium is conveyed and an arrangement direction in which the nozzle array is arranged are parallel to each other, and at a predetermined timing, at least one ejection head among the plurality of ejection heads moves to a position facing the ejection target medium and ejects the droplet toward the ejection target medium, and, simultaneously, a remaining ejection head among the plurality of ejection heads other than the at least one ejection head moves to be withdrawn from the position facing the ejection target medium and ejects the droplet toward the ejection receiver.

A thread-coating system includes: a thread-coating module having a droplet ejector assembly; a thread gatherer positioned upstream of the thread-coating module and configured for arranging a plurality of threads in a thread wall; a thread expander positioned downstream of the thread-coating module for receiving a coated thread wall and expanding the coated thread wall into individual threads. The thread gatherer is configured for adjusting a spacing of threads in the thread wall and an overall height of the thread wall via a pivoting motion.

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.

A system for in-line treatment of thread for use with a thread consuming unit is provided. The system includes a treatment unit including at least one discharge device being configured to dispense one or more coating substances onto the at least one thread when activated. The system further includes a control unit configured to evaluate the thread consumption of a thread consuming device based on operation data and at least one parameter being related to one or more thread consumption parameter, and control the dispensing from the discharge device based on said evaluated thread consumption and/or adjust the thread consumption of the thread consuming device.

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.

The present invention relates to a dyeing machine (1) having at least one each vertical guides (24) positioned at the two sides of at least one body (20) for realizing dyeing during wrapping of the yarn (223) from at least one first bobbin (21) to the second bobbin (22), at least one sprayer drive mechanism (17) which can move vertically on said vertical guide (24), at least one bobbin carrier (224), at least one drum (23) which contacts the surface of said second bobbin (22) positioned on said bobbin carrier (224), at least one first drive element (231) where said drum (23) is connected from one side for providing movement of said drum (23), at least one fourth drive element (171) for moving said sprayer drive mechanism (17), at least one sprayer (16) which realizes dyeing while the yarn (223), positioned on said sprayer drive mechanism (17), is wrapped onto the second bobbin (22), and at least one pump (14) connected to at least one dye kier (11) for obtaining the dye needed by said sprayer (16). The improvement of the present invention is that in order to provide realization of stamping dyeing, the subject matter dyeing machine (1) comprises at least one sensor (18) which detects the deviation between the position of the sprayer (16) and at least one predetermined stamping region (221) on said second bobbin (22), at least one second drive element (232) configured to rotate the second bobbin (22) in a direction which is opposite to the direction of the first drive element (231) in order to provide alignment of the sprayer (16) with said stamping region (221), and at least one control unit (30) associated to said sensor (18) in order to control the operation of said fourth drive element (171) by means of said second drive element (232).

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.
