Abstract

A device for coloring a thread body includes a thread-feeding unit adapted for feeding the thread body at a predetermined speed such that the thread body is transported along a feeding path. A coloring unit is disposed fixedly adjacent to the feeding path, and is operable so as to spray a coloring material onto the thread body. A control unit is connected electrically to the coloring unit, and is operable so as to control the coloring unit to spray the coloring material, which has a desired one of a plurality of different colors.

Claims

1. A device for coloring a thread body, comprising:

a thread-feeding unit adapted for feeding the thread body at a predetermined speed such that the thread body is transported along a feeding path;

a coloring unit disposed fixedly adjacent to the feeding path and operable so as to spray a coloring material onto the thread body; and

a control unit connected electrically to said coloring unit and operable so as to control said coloring unit to spray the coloring material, which has a desired one of a plurality of different colors.

2. The device as claimed in claim 1, further comprising:

a display unit connected electrically to said control unit for displaying color information corresponding to the different colors and status information indicating the desired one of the different colors; and

an operating unit connected electrically to said control unit and operable so as to output a control signal corresponding to the desired one of the different colors to said control unit so that said control unit controls said coloring unit to spray the coloring material having the desired one of the different colors based on the control signal from the operating unit.

3. The device as claimed in claim 1, further comprising a sensor connected electrically to said control unit and adapted to be disposed adjacent to the feeding path for sensing movement of the thread body, said sensor outputting a detecting signal to said control unit upon detecting that the thread body ceases to move so that said control unit deactivates said coloring unit based on the detecting signal from said sensor.

4. A sewing machine comprising:

a housing;

a thread-feeding unit mounted on said housing and adapted for feeding a thread body at a predetermined speed such that the thread body is transported along a feeding path;

a coloring unit mounted fixedly in said housing, disposed adjacent to the feeding path, and operable so as to spray a coloring material onto the thread body; and

a control unit mounted in said housing, connected electrically to said coloring unit, and operable so as to control said coloring unit to spray the coloring material, which has a desired one of a plurality of different colors.

5. The sewing machine as claimed in claim 4, further comprising:

a display unit mounted on said housing and connected electrically to said control unit for displaying color information corresponding to the different colors and status information indicating the desired one of the different colors; and

an operating unit mounted on said housing, connected electrically to said control unit, and operable so as to output a control signal corresponding to the desired one of the different colors to said control unit so that said control unit controls said coloring unit to spray the coloring material having the desired one of the different colors based on the control signal from the operating unit.

6. The device as claimed in claim 4, wherein said coloring device further includes a sensor mounted on said housing, connected electrically to said control unit and disposed adjacent to the feeding path for sensing movement of the thread body, said sensor outputting a detecting signal to said control unit upon detecting that the thread body ceases to move so that said control unit deactivates said coloring unit based on the detecting signal from said sensor.
