About JF Sequin Embroidery

1. Brief of Sequin Embroidery

Sequin embroidery is formed by many sequins and the specific stitch form. Because the sequins are made of the hard and shining material with smooth surface, the sequin embroidery, formed by the sequins with different colors, shapes and sizes, features the unique shining effect. The design with sequin code has its own pattern format.
JF Type multi-sequin embroidery is divided into two types on the designs: one is normal multi-sequin design, made by the traditional pattern-making method; the other is special multi-sequin design, made by the normal design software with the special pattern-making rules.

For normal multi-sequin design, user should set sequin mode when modifying the color-changing order. But the special multi-sequin design can be directly embroidered only after modification of color-changing order, which means user doesn’t need to set the sequin mode.

Meanwhile, the machine can automatically change normal design to special design during the process of design import. The new special design saves the entire sequins in the original normal design as sequin A. If you want further modification, you can use “Sequin Edition” to modify. The multi-sequin design after the modification is the special multi-sequin design.

5. Setting of Multi-Sequin Embroidery Parameters

In this section, we will introduce how to adjust sequin device and the parameters used in multi-sequin embroidery.

Select  in the main interface to enter parameter management interface, then select Sequin Parameters to have access to the interface for setting the sequin parameters.

  1. Limited Speed for Sequin R(L):
    The parameter is to set the max speed during normal embroidery.
    Note: the maximum speed of flat embroidery should be higher or equal to speed for sequin embroidery.

  2. L/R Sequin Feeding Angle Adjustment
    This parameter is to adjust the sequin-feeding angle.

  3. Auto Start for Sequin
    When the setting is “Yes”, system will start embroidering sequin automatically.
    When the setting is “No”, machine needs manually start at sequin embroidery.

  4. Time of Sequin Action
    This is to set the time from sequin device going down to starting embroidery (0-15, the default value is 2). If the sequin-feeding device is controlled by valve, use the default value; if that device is controlled by motor, please set it at 4~5.

  5. Sequin off after T.B.
    When the setting is “Yes”, sequin presser foot will be up automatically in case of thread-breakage.
    When the setting is “No”, the user needs to lift the presser foot manually at thread-breakage.

  6. Sequin Ind. Up/Down
    When the setting is “Yes”, the sequin devices will move independently. When the setting is “No”, they will move collectively

  7. Lift Valve at Jump without Trim (Y/N)

  8. Base of Shift Travel at L/R Motor

  9. Multiple of Shift Travel at L/R Motor

  10. Has Origin at Shifting L/R Motor
    The parameter No.8, No.9 and No.10 are for the special sequin device that uses the motor (Single Needle Double Sequin) to shift the travel between large sequins and small sequins. There are two kinds of device: one has the shift origin; the other has no shift origin.

  11. Beam-breakage Detection Sen.
    This parameter is used for the beam embroidery device. “0” is to turn off the sensitivity, the range of this parameter is 0~10. The smaller value means the higher sensitivity of the detection device.

  12. Motor Number of L/R Sequin
    The setting of this parameter should be based on actual device condition, if there is no sequin device, please set it at 0.

  13. Set 3/4/5/6.75/9mm of L/R Sequin
    This parameter group is to set the sequin delivery angle. If it is wheel type sequin-feeding device, please set it at single way; if it is lever type sequin-feeding device, please set it at double ways. The parameters of this type are set correctly when the machine is produced. This kind of parameters is closely related to “left/right sequin device A/B/C/D size and color”. For example, “A size&color of R sequin” is set to “4mm X color”, and then the angle value should be the one in “Set 4MM of R Sequin”.

  14. A/B/C/D Size &Color of R/L Sequin
    The setting of this parameter should depend on the mechanical structure. The corresponded order from A to D is front motor to back motor.
    Note: “Motor Number of L/R Sequin” is closely related to the number of A/B/C/D in “A/B/C/D Size&Color of R/L Sequin”. For example, if “Motor Number of L/R Sequin” is set to 2, then only the “A/B size&color of R/L sequin” will be displayed.

  15. Sequin Gap Num. of L/R Sequin
    This is to set gap number. If there is no gap, then it should be set to 0.

  16. L/R Sequin Valve Action Time
    This parameter is for setting the response time at adjusting the valve action. The larger value means the longer response time. Please set it according to the actual condition of device. Default value of it is 2.

  17. L/R Trimmer Action Angle Adj.
    This parameter is used at the special sequin device that uses motor to cut the sequin for adjusting the start time of the sequin-cutting motor. The default value of it is 15. The smaller value means the earlier action of motor, the range of this value is 0~31.

6. Change Color Order and Set Sequin Mode
