An embroidery system includes a coloring device to color a thread. The embroidery system includes an embroidery device to perform embroidery of an embroidery design and underlay stitching. The embroidery device uses the thread colored by the coloring device for at least one of the embroidery of the embroidery design or the underlay stitching. The embroidery system includes circuitry to: create data of the embroidery design and the underlay stitching according to embroidery image data; create color data for coloring the thread to be used for coloring the at least one of the embroidery of the embroidery design or the underlay stitching; acquire roughness data representing roughness impression of the embroidery image data; and change an embroidery density of the embroidery design according to the roughness data.

An embroidery system includes a data reading device to read three-dimensional data of a design of an embroidery. The embroidery system includes processing circuitry to process the three-dimensional data read by the data reading device, to create embroidery data using height information included in the three-dimensional data. The embroidery system includes an embroidery forming section to form the embroidery on a target object according to the embroidery data created by the processing circuitry. The embroidery system includes a recording head to discharge a liquid droplet from a nozzle. The embroidery system includes control circuitry to control an operation of the recording head. The embroidery data includes data relating to an embroidery density that is a density of a thread in the embroidery and data relating to an application amount of the liquid droplet to be applied to the thread in the embroidery.

A liquid application unit includes a supply member, a liquid application device, and an application controller. The supply member includes a cylindrical or columnar winding core around which a linear medium is wound. The liquid application device applies liquid to the linear medium unwound and fed from the supply member. The application controller adjusts a liquid application length of the liquid applied by the liquid application unit to the linear medium in a feed direction of the linear medium. The application controller adjusts the liquid application length in the feed direction of the linear medium in accordance with a winding thickness of a remaining amount of the linear medium from an outer peripheral surface of the winding core.

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 dyeing apparatus is configured to be connected to an embroidery apparatus. The dyeing apparatus includes a dyer configured to dye a thread; a conveying path in which a path length of the thread from the dyer to the embroidery apparatus is changed according to an operation of the embroidery apparatus; and a conveyance control unit configured to adjust a conveyance speed of the thread in the conveying path, according to a change in the path length. The dyer dyes the thread at a dyeing speed that matches the adjusted conveyance speed.

A wax dispenser for conditioning sewing thread includes a disc-shaped housing (12) with upper and lower surfaces (14, 16), a sidewall (18), and a cavity (20). Peripheral slots (22) allow thread to engage a disc-shaped wax bar (28) within the cavity, applying wax to the thread. A dial assembly (26) in a dial opening (24) rotates the wax bar, presenting fresh wax to the slots as needed. The dial assembly includes a circular support member (32) with engagement fins (30) to secure and rotate the wax bar. The dispenser addresses wax depletion near thread feed slots, ensuring consistent thread waxing. The dispenser is primarily used for sewing thread conditioning, with polystyrene preferred for the housing and dial components.
