Postbed machine with computerized independent double rollers feeding and intelligent control: it is the perfect choice for variety of high-end leather shoes, sports shoes, suitcases, bags, gloves, leather products such as clothes, hats, etc.
The JACK S7-91-T is the upgrade from the S5-91 and is currently the most-advanced post-bed lockstitch sewing machine and is best-suited to the sewing of heavy-weight materials sewing processes such as car-seats, sofas and sports goods.
The large 5-inch touch screen is easy to use and allows you to change the speed, stitch length, sewing modes and other parameters in Italian.
In addition to the main shaft motor, the machine has 3 other stepper motors: one on the needle bar for the needle feeding and the other two independent on the rollers to which the differential can be set. All this allows a more accurate, quick and silent sewing.
Quickly and precisely adjust the pressure of the roller using a screw located in the upper part of the machine.
A button has been inserted to quickly change the stitch length.
The bartack lever is made of a double layer, so that the second part can be extracted by extending it and making it easy to use with the arm while sewing.
Thanks to the step-by-step motors it is possible to create ornamental stitches by programming different stitch lengths and stitch repetition as desired.
The structure of the handwheel works as a fan capable of keeping the internal components at about 4 degrees less than other machines, extending the life of the machine.
Ensures the same distance from seams, also prevents the thread from loosening during the tight stitch, when the thickness of the fabric changes or in corner seams.
It can penetrate more than 110 layers of A4 paper, and the ultra-heavy fabrics of work shoes can be easily sewn.
In addition to the dimmable light with multiple shades and intensities, we have added ultraviolet light to increase the visibility of the drawn line of the seam.
Precise and clean thread trimmer, thanks to its new design the thread is cut to just 3mm so you don't have to trim it by hand, saving time and money.
Automatic detection of the thread less than 30cm remaining in the bobbin, automatic stop for bobbin replacement, it maintains the quality of the fabric without punching it empty.
Stitch length can be changed over among different lengths:
The sewing machine with a thread trimmer is provided as standard with a 2-pitch dial. One unit of this sewing machine can sew different sewing lengths since the sewing length can be instantaneously changed over.
Reduction of noise and vibration:
Reduce weight by using resin parts for the surface of vibration point. Noise and vibration decrease by changing the gear of a hook into a bevel gear.
High-torque direct-drive motor is installed:
The sewing machine provided with a thread trimmer has adopted a high-torque direct-drive motor which is suitable for heavy-weight materials. Asa a result, the sewing machine is excellent at its responsiveness and ensures increased penetration into the material even when sewing multi-layered parts.
Eccentricity of the feed driving cam is adjustable:
Adjustment of the eccentricity of the feed driving cam has been enabled. As a result, the sewing machine can perform sewing with feed that is best-suited to the material and thread used. It is no longer necessary to prepare other subclass model sewing machines.
The upper and lower feed ratio is adjustable:
The upper and lower feed ratio can be changed only by the adjustment of the lower feed amount without changing the upper feed amount, thereby preventing material slippage.
