Wire coil for use in wire sawing device, has ring separated from other ring when parts of coil are separated for permitting removal of wire from coil, where parts which are removable from each other follow central axis

摘要

The wire has a set of wires between two wire-guide rolls, in which one of the wires is moved according to continuous or reciprocating movement in support against a part to be sawed for being rolled on a coil. Rings (25, 27) and a spindle (26) are aligned along a central axis (38). Parts (28, 29) of the coil, which are removable from each other follow the central axis, and the ring (25) is separated from the other ring (27) when the parts of the coil are separated to permit the removal of wire from the coil. The spindle has a conical portion (33) whose surface make an angle with the axis.
