Abstract

841,779. Moulding drills. KLEIN, M. L. Oct. 1, 1957 [Oct. 4, 1956; Aug. 16, 1957; Sept. 25, 1957], No. 30645/57. Class 87(2). [Also in Group XXII] A drill comprises a socket of mouldable material 3 cast over a wire 2. The wire rests in grooves 6, 9, Fig. 5, in an injection mould-part 4. The force of the injection may bend the wires as shown in Fig. 3. The socket may have an external taper or an internal taper 3, Fig. 4. In a modified apparatus, the wire is gripped by jaws on a member 18, Fig. 7, which can be moved axially to eject the finished article. The mouldable material may be nylon, or a synthetic glue hardening at room temperature.
