The spacing of looper is adjusted, the distance between adjustable same group of 2 looper can also adjust the distance between 2 groups of loopers, full
The demand of foot difference waistband sews the stitching diversification come, meets the aesthetic requirement of different crowd.
(7) it is from the beginning to be sewn to tail when existing drawing waist machine sews, for beauty, needs to dismantle at both ends and, then inwardly
It gets involved in, then sutures the both ends to form more neat appearance.The work that both ends are dismantled all is to greatly reduce work by being accomplished manually
Make efficiency.It is equipped with using drawing waist machine of the invention and blows empty needle component, the needle number that the beginning hollow joint of waistband can be made to set, when sewing is fast
At the end of, the also certain needle number (can be set as needed) of corresponding hollow joint, thus after waistband is sewn on cloth, no
It needs manually to take out stitches again, greatly improves working efficiency.
(8) application drawing waist machine of the invention is equipped with shear, when starting sewing, can will start extra waistband and cut
Fall, keep the neat of initial position, waistband can be automatically cut off after terminating sewing, greatly improve working efficiency.Shearing dress
The upper cutter set is equipped with guide part, so as to make upper cutter and lower cutter separate it is biggish dehisce, adapt to the cloth of different-thickness
Material can reduce upper cutter and the lower cutter length upward in left and right closer to left side cloth when installation, material saving, simultaneously
Installation space is saved.
(9) application drawing waist machine of the invention, which is equipped with, compresses wheel assembly, and waistband corresponding site can be pressed on to lower tugboat component
It is lower after on tugboat, it is lower after tugboat be equipped with rear withdrawing roll, post-tensioning roller surface, which is equipped with, rolls tooth, waistband can be made to keep tensioning state,
Convenient for shearing, notch is more smooth, and is easy cutting.
(10) application drawing waist machine of the invention is equipped with cooling component, and cooling component is used to cool down to eedle, is conducive to continuous
Sewing operations prevent high temperature from be deformed cloth.
(11) application drawing waist machine of the invention is equipped with foot pedal, can liberate both hands, improves working efficiency, guarantees sewing matter
Amount.
