Claims
- 1. An apparatus for forming annular members, such as packing rings, of substantially any material and with substantially any dimensions with the number of parts in use remaining constant, said apparatus comprising:
- a base plate;
- a header plate;
- an axial pin member extending through and substantially normal to said plates;
- a plurality of concentic cylindrical members selectively arranged in three groups between said plates to define a core, a housing coaxial with said core and defining an annular cavity therebetween, and an annular ram of dimensions substantially equal to said cavity; and
- means to apply compressive forces to drive said plates towards each other and against said cylindrical members whereby fiberous packing material deposited in said cavity is compressed into annular form.
- 2. An apparatus according to claim 1 wherein:
- said means to apply compressive force is screw means applied to said axial pin member.
- 3. An apparatus according to claim 1 wherein:
- said means to apply compressive force is a press acting on said plates.
- 4. An apparatus according to claim 1 wherein:
- said axial pin is fixed to said base plate.
- 5. An apparatus according to claim 1 further comprising:
- a peripherial flange on said base plate coaxial with said pin member whereby said housing forming cylindrical members are positioned coaxially with said pin.
- 6. An apparatus according to claim 1 further comprising:
- scale means on at least one of said plates whereby the relative movement of said plates towards one another can be measured.
