A thread-coating module includes: a base plate having a printhead opening; an inkjet printhead received in the printhead opening; and a chamber unit having a mouth for engagement with the base plate and an ink-collection slot opposing the printhead. The chamber unit and the base plate are movable relative to each other for opening and closing a coating chamber comprising the base plate and the chamber unit, with the ink-collection slot being positioned opposite the printhead in the coating chamber.

A system and method for treatment of thread includes a thread printer that applies colored coatings to thread. A camera is positioned to capture images of the treated thread after it passes through an outlet of the thread printer. The system processes the images to determine whether the location of a selected segment of the treated thread corresponds to an expected location. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of one or more segment to automatically account for the misalignment.

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.

A method and device for controlling the fixation of a treatment material being applied to a thread during a thread treatment process are disclosed. The method comprises performing a thread treatment process, forming part of the thread consuming process, by: i) applying a treatment material to the thread; and ii) applying an amount of energy to the thread to at least partly fix the applied treatment material to the thread; wherein the method further comprises controlling the amount of energy being applied to the thread as a response to a detected operational status of the in-line thread consuming process.

This weaving machine (2) is for simultaneously weaving a top pile fabric (F2) and a bottom pile fabric (F4), each pile fabric 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 comprises a pile warp yarns feeding unit (20), a binding warp yarns feeding unit (18), a shedding unit (6) for creating a shed with the pile warp yarns and the binding warp yarns (14, 16). A weft insertion unit (8) is used for inserting the weft yarns in the shed in successive insertion cycles. A beating-up mechanism (32) is used for beating the weft yarns into the shed. A take up system (70) is used for taking-up the two pile fabrics. A drawing-in unit (26) draws the pile warp yarns from the pile warp yarn unit (20) and a control unit (80) controls operation of the weaving machine (2). This weaving machine also comprises a treatment unit (90) located, along a path of the pile warp yarns (24), between the pile warp yarns feeding unit (26) and the shedding unit (6), for applying different segments of treatment on at least some of the pile warp yarns (24).

A system and method for treatment of thread includes a thread printer that applies colored coatings to thread and that passes the treated thread to a fabric weaving system. A camera is positioned to capture images of the treated thread as it is woven into a fabric in the fabric weaving system. The system processes the images to determine whether the location of a selected segment of the treated thread in the fabric corresponds to an expected location in the fabric. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of a segments to automatically account for the misalignment.

A liquid discharge apparatus includes a liquid discharge head including a nozzle face in which a nozzle is formed and configured to discharge a liquid, a carriage on which the liquid discharge head is mounted, and a guide shaft configured to hold the carriage movably. The liquid discharge apparatus further includes a driver configured to move the carriage, and a coupling between the carriage and the driver. The coupling is disposed on an axis of the guide shaft in a direction orthogonal to the axis of the guide shaft.

A liquid discharge apparatus includes heads to discharge a liquid; caps to contact and move away from the plurality of heads, respectively; individual drain passages communicating with the plurality of caps, respectively; at least one common drain passage communicating with at least two of the individual drain passages; suction devices provided in the individual drain passages, respectively; and a controller. Each of the individual drain passages is to allow and shut off communication between the cap and the common drain passage. The controller causes the individual drain passage to allow the communication between the cap and the common drain passage when performing capping and decapping of the head. The controller caps the sucking target with the cap after shutting off each individual drain passage communicating with the cap corresponding to the head that is not a sucking target.

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).
