The fabric will be simply clamped or fed.
The software based on a PC is calculating the distancies from pleat to pleat.
Pleats from 10 to 100 mm.
The distances can also be entered manually on the touch screen TFT.
The pleat will be made automatically by a system moving from the back to the desired position to build a pleat in the desired depth
The pleat will be clamped - the system moves back - the sewing process starts from the right to the left.
Sizes of the pleats and distances from pleat to pleat are programmable.
The sewing head runs back from left to right and starts the next operation.
