Abstract

The present invention relates to a semi-automatic device for sewing full felled inseams or outer seams on jeans. The fell seamer employs optical sensors and spline rolls to guide the material into and through the folder. Sensors are embedded in the folder of the device to indicate the amount of material to be introduced into the folder. A computer controlled interface indicates the adjustments to be made and automatically sends instructions to the machine to effect the adjustments. The full fell seamer device includes an upper cylinder assembly, an upper pivot assembly, an upper spline assembly, an upper flex shaft assembly, a lower cylinder assembly, a lower spline assembly, a folder assembly, an upper motor assembly, a lower flex shaft assembly, a control box assembly and a pneumatic assembly. The vision, logic and drive systems sense the material being fed and compute the information gathered and then effect the drive system functioning as required by the material to be sewn.
