Abstract
A method of making a face mask including the steps of providing a plurality of lengths of Grade 2, commercially pure titanium wire, having a diameter of from about 0.21 to about 0.24 inches; forming each length at room temperature to a desired bend angle by bending the member at room temperature using rotary bending apparatus to a first bend angle that is from about 1.25 to about 1.35 times greater than the desired bend angle; and welding each of the thus formed lengths to at least one other of the lengths in an ambient, oxygen containing environment.
Claims6
A method of making a face mask, comprising the steps of:
- providing a plurality of lengths of Grade 2, commercially pure titanium wire, having a diameter of from about 0.21 to about 0.24 inches;
- forming each length at room temperature to a desired bend angle by bending the length at room temperature using rotary bending apparatus to a first bend angle that is from about 1.25 to about 1.35 times greater than the desired bend angle;
- welding each of the thus formed lengths to at least one other of the lengths in an ambient, oxygen containing environment, wherein the face mask complies with the Standard Method of impact and Performance Requirements of the National Operating Committee on Standards for Athletic Equipment (Jul. 14, 1987, revised Jul. 10, 1990).
A method of making a face mask, comprising the steps of:
- providing a plurality of titanium wire members;
- positioning the wire members in a desired configuration;
- and
- interconnecting the wire members to one another by welding using resistance spot welds formed in an ambient, oxygen containing environment, wherein the face mask complies with the Standard Method of impact and Performance Requirements of the National Operating Committee on Standards for Athletic Equipment (Jul. 14, 1987, revised Jul. 10, 1990).
