Abstract
A cutter for cutting material in tape form comprises a movable blade of circular segment shape in cross-section and a fixed blade. The movable blade is coupled to a rotating shaft so as to move it in front of the fixed blade. A first support carrying the fixed blade is U-shaped in cross-section, the inside of its bottom being semi-circular. A longitudinal first opening intersects the bottom of the first support and a groove opens laterally into this first opening in its inside surface, the groove accommodating the fixed blade. An auxiliary support is generally trough-shaped and has a bottom which is semi-circular on the inside. A second opening intersects the bottom of the auxiliary support, the edges of which are inserted between the sides of the U shape of the first support. A substantially cylindrical housing for the movable blade is defined between the first and auxiliary supports. Snap-fastener means maintain pressure on the first and auxiliary supports to permit rotation of the movable blade in this housing without axial play. The movable blade is operated to close off the first opening when the cutter is closed and to move to the same side as the first and second openings wi…
