Abstract: This invention concerns a segmenting device in particular for the manufacture (portioning) of sausages from a string of sausage filling in a flexible tubular casing, which consists of a plurality of tye elements (12) in the form of strips which can be rotated against each other. One of their ends is secured locally in a ring concentric to the axis of the casing at regular intervals, and whereas the other end region is collected to form a ring (11) concentric with the axis of the casing, which, relative to this, can undergo movement of a rotational nature as well as parallel movement in their major plane, at least tee tying elements are provided, whose contact surface segments, which face the opening, are bent or curved in the main plane. In this manner each strip impinges on the casing with several contact surface segments and promotes the radial tying of the casing, avoiding shearing movements between the casing and the strips.
