Description
The number of stitches and size of bar tacking
The number of stitches to sew a belt-loop can be switched between; 28-, 36-, and 42-stitches, and the bartacking size can be easily changed through the operating panel. What’s more, the user can create his/her original sewing patterns in addition to the standard ones using JUKI’s PGM-20 programming software developed for computer-controlled sewing machines.
The changeover of cutting method between cross-cutting and straight-cutting
The applicable loop width for the cross-cutting device is increased. In this model, both the cross-cutting device and the straight-cutting device can now cut loop up to 20mm width.
The machine time is 1.2 seconds per belt-loop (with 28 stitches)
The new machine head specifically developed for belt-loop attaching machines runs at a maximum sewing speed of 2,500rpm and is equipped with a direct-drive system that improves start-up performance and shortens sewing time. The belt-loop feeding device is now provided with a halfway standby capability for subsequent belt loops, and its faster belt-loop supply action shortens the time required for supplying belt loops and helps speed up the machine time to 1.2 seconds per belt loop (with 28 stitches).
With the improved consistency in belt-loop supply action and re-try capability, the machine down time is substantially reduced
Belt-loops are fed out by the conventional gear-roller feeding mechanism and also drawn out by the new drawing mechanism on the clamp device. Supported by these two mechanisms, the folding fork catches “curled” or “creased” belt-loops every time and supplies them to the head. In addition, the sensor of the clamp device detects the presence/absence of belt-loops. If it detects a faulty belt-loop feed, the clamp device automatically repeats the clamping action. Since the operator doesn’t have to operate the set-back switch, less time is lost.
