Take making as example that above-mentioned Z-shaped shape is made, performed some controls that should stress of CPU 81 of control module 80 are described here.
[1] double sewing line formation control
The program of CPU 81 by putting rules into practice, on the width of the band B of band clamping plate 31 clampings, the stitching L2 that formation is made as the folding line of folding line (with reference to Fig. 7 (C)), utilize the Y-axis motor 36 of clamp mechanism 30, make band clamping plate 31 move (with reference to Fig. 8 (A)) to the direction of turning back from this stitching L2, on the stitching L2 that is in the state that the band B that turned back blocks, form the stitching L3 (with reference to Fig. 9 (A)) as double sewing line.
In above-mentioned control, because belt loop sewing machine 10 adopts the structure of only carrying forked parts 38, so end for band B, can utilize forked parts to be turned back in this end, and form from the upper side stitching, but to be difficult in order solving the problem of utilizing 38 pairs of other ends of forked parts to turn back, and for the other end, to utilize band clamping plate 31 to realize turning back.
Namely, pulling by band clamping plate 31, take stitching L2 as folding line, band B is turned back, thus band B is turned back, and further becoming owing to turning back on double-deck end of turning back, make stitching L3 from the top, thereby realize to utilize the turning back of the other end of the band B that forked parts 38 turn back.
[2] the double sewing line position correction is controlled
The double sewing line position correction is controlled, and is to accompany and the control of execution with the execution of above-mentioned double sewing line formation control.The program of CPU 81 by putting rules into practice, when the stitching L3 as double sewing line in the double sewing line formation control forms, carry out following control, namely, the second Y-axis motor 74 to cloth pressing mechanism 70 is controlled, with with as setting the corresponding apart from m2 of correcting value, stitching L3 is proofreaied and correct with respect to the formation position of stitching L2.
In the prior art, due to cylinder as drive source, carry out the switching of stitching position, make so can only switch by the position at assigned position place, but belt loop sewing machine 10 be owing to can utilize the second Y-axis motor 74 that cloth C is moved on Y direction via cloth pressing 71, overlaps the upper and sewing position of the double sewing line L3 that makes of folding line stitching L2 so can make, accordingly, be offset on Y direction with setpoint distance m2 (setting correcting value).
In addition, stitching L3 compares with stitching L2 and is formed on inboard (stitching L1 side), but is not limited to this, also can set corrected value, is formed on the outside so that stitching L3 compares with stitching L2.
[3] band returns to control
Band returns to control, is to accompany and the control of execution with the execution of above-mentioned double sewing line formation control.The program of CPU 81 by putting rules into practice, after folding line stitching L2 in the double sewing line formation control forms, Y-axis motor 36 to clamp mechanism 30 is controlled, so that band clamping plate 31 move to the direction that band B is turned back, when stopping, band clamping plate 31 are returned to opposite direction slightly, and to be in the band B of state of extension lax because of pulling thereby make.
Thus, eliminated via band B making cloth C by the state that band clamping plate 31 pull, eliminated cloth C is sewed up with band B under the state that is stretched, or each stitching position is due to pull former thereby produce the problem of distortion.
