ABSTRACT:
The sewing machine is used for looping or linking floor coverings and is transportable, so that, apart from being used in stationary manner, it can also be moved along the material edge to be looped. It produces a two-thread overcast seam and has a cutting device with a knife (108) for rounding the material corners prior to looping and is automatically started up under the control of a photoelectric cell (117) on approaching a corner.
