Abstract

Improvements in regulable differential transport devices for sewing machines, comprising a main grapple and a differential grapple, each of which is kinematically connected to its own eccentric, mounted on a rotating shaft, characterized by the fact of understanding, combined, an eccentric (2) of the differential hook (12) mounted idle on an eccentric part (25) of the said rotating shaft (3), friction means (22) and (23) to maintain the eccentric chirping on said eccentric part when turning the axle, said eccentric (2) being angularly locatable on said eccentric part to avoid the eccentricity resulting from the sum of the eccentricity of the eccentric part (25) with the eccentricity of the eccentric (2) of the differential hook (12).
