ABSTRACT:
A regulating device for the upper wheel type workpiece transport mechanism in sewing machines. The transport wheel is rotatably driven and carried by a tubular support pivotably mounted on the machine. An eccentric roller having an indicating arm extending therefrom is in operative contact with the tubular support and with one end of the indicating arm disposed in operative association with a graduated scale defined by a plurality of stops for selectively locating the indicating arm. By moving the latter to any one of the stops, the eccentric roller is effective in changing the operating position of the transport wheel so that it can accommodate workpieces which vary in thickness and with generally the same amount of pressure being applied to each workpiece.
