ABSTRACT:
A tensioner unit in a thread supply path for a domestic sewing machine which by its structural arrangement and location on an upper face of a machine provides a feed path across the frontal face of the machine for full visibility and accessibility of the thread without obstructing the view of the work area. The feed path through the tensioner unit is also arranged to provide a wrap of thread through the unit about a vertical axis in excess of 180 degrees to provide stable frictional engagement of the thread in the tensioner unit.
