Abstract

A separator-spacer device for flat objects, such as postal correspondence, in which the objects to be handled are fed into the V space formed by the opposing branches (25, 26) of two bands (27, 28), which are urged resiliently against each other, in order to define a first pinch point (38). One band (27) has a high coefficient of friction and moves in feed direction (16) of the objects, the other band (28) moves at a lower speed in opposite direction and has a lower coefficient of friction. Downstream of the bands (27, 28) there is provided a belt conveyor (41, 45) moving at a greater speed than the first band (27), and forming a second pinch point (51) spaced apart from the first by a distance less than the minimum length of the objects.
