Abstract
A belt (10) has cylinders (12) formed integral with a body (11) to hold a row of self-drilling reaming screws (20) each having a head (25), a threaded shank (21), a drill tip (22) and reaming blades (23) disposed on the tip and near the shank. The belt further has slits (13) extending radially from each cylinder, and lateral cutouts (15) intermittently drive the belt at the same pitch as the cylinders. Each cylinder is prismoidal between its wider inlet and narrower outlet so that a distance A between the cylinder's walls gradually decreases towards the outlet, but at the inlet this distance is substantially equal to the diameter d.sub.1 of an envelope circle of the blades. Inner edges (13a) of the slits (13) facing one another and disposed in and from the regions' inlet sides are spaced also the same distance B as the diameter d.sub.1 so that each screw can take a correct position on and perpendicular to the belt, thus enabling it to be loaded with the screws smoothly and efficiently.
