(2) Explanation of control panel CP-160 1) Reverse stitching pattern When the sewing machine performs the free stitching operation, the machine performs the reverse stitching operation at the start and end of sewing. The reverse stitching operation can set the ON and OFF settings. Furthermore, single and double reverse stitching patterns can be selected. Setting of number of stitches or other settings can be performed by operating the control panel. A, B, C and D = 0 to 19 stitches 2) Overlapped stitching pattern The sewing machine repeats the normal stitching and reverse stitching by the predetermined time, and performs the line bartacking. Then, the machine makes the thread trimmer actuate and stop to complete the overlapped stitching procedure. Change of the number of stitches or the number of times of repetition can be performed by operating the control panel. A, B and C = 0 to 19 stitches D = 0 to 9 times 3) Constant-dimension stitching pattern The free stitching process in the reverse stitching pattern becomes the set value of the number of stitches. The sewing machine will automatically stop (automatically perform thread trimming if the automatic thread trimming is selected.) after the machine finishes the predetermined number of stitches in the process of CD. If the automatic thread trimming is not selected, operate the touch-back switch after the machine has automatically stopped. Then, the machine runs at a low speed (stitch compensation operation). Also, if the pedal is returned to its neutral position and depressed its front part again, the sewing can be continued regardless of the setting of number of stitches. Setting of number of stitches or selection of automatic thread trimming can be performed by operating the control panel. A and B = 0 to 19 stitches CD = 0 to 500 stitches 4) Rectangular stitching pattern There are 4 operation steps in the process of constant-dimension stitching pattern. At each operation step the sewing machine automatically stops after sewing the predetermined number of stitches. At this time, if the touch-back switch is operated, the sewing machine runs at a low speed (stitch compensation operation). Also, in case of the last operation step, if the pedal is returned to its neutral position and depressed its front part again, the sewing can be continued regardless of the setting of number of stitches. However, if the automatic thread trimming is set, the machine will perform thread trimming. Setting of number of stitches or selection of automatic thread trimming can be performed by operating the control panel. A and B = 0 to 19 stitches C and D = 0 to 99 stitches

(3) Example of application 1) When the CP-160 is used together with the material end sensor (ED : optional), it can be used as a small edge-controller. (Method) Adjust the position to mark 3 of the CP-160, turn ON material end sensor ON/OFF switch !2 of the CP-160, and turn ON mark !3 of the automatic one-shot stitching. (Caution) 1. Number of rotations of the automatic one-shot stitchig can be changed by the function setting (No. 38). 2. It is necessary to set the material end sensor input of the function code : 9 to the input port by using the function of the optional input/output function selection (Function setting No. 12). 3 !2 !3

2) Label attaching is performed by the automatic one-shot stitching with the CP-160 (Method) Select mark 5 on the CP-160, and turn ON mark !3 of the automatic one-shot stitching. (Explanation) Number of stitches at the section CD can be set up to 500 stitches. If the stitch length is 2 mm, it is possible to sew approximately 1,000 mm (1 m). This function can perform the automatic one-shot stitching without using the material end sensor (ED : optional). Therefore, the sewing machine performs the sewing to the last according to the sewing pattern even if the label is not located at the end of material when the pedal is depressed once.
