Abstract
Abstract A method of making a supporting medium having a plurality of spaced holes comprising the steps of forming a sheet of material with a plurality of spaced elongated elements such as wires embedded therein and removing the elongated elements to form spaced holes in said sheet. In a preferred embodiment, a laminate is formed by positioning a plurality of elongated elements between two sheets of material, bonding the sheets together and removing the elongated elements to form spaced holes in the laminate. Where the supporting medium is to be used to support magnetically coated memory wires, the supporting medium should be of nonmagnetic material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
15 words
In the process of claim 1 wherein said sheets of insulating material are thermoplastic material.
Claim 2
Dependent Claim
16 words
In the process of claim 1 wherein each wirelike element is coated with a release agent.
Claim 3
Dependent Claim
45 words
In the process of claim 1 wherein said elongated wirelike elements extend substantially the length of said first and second sheets, and said holes formed in said cohesive strip by the removal of said elongated wirelike elements also extend the length of said cohesive strip.
Claim 4
Independent Claim
128 words
A method of making a supporting medium having a plurality of spaced holes and adapted to support within said holes a plurality of wires having a coating of magnetic material, said method comprising the steps of forming a sheet of nonmagnetic thermoplastic material with a plurality of spaced elongated metallic elements embedded therein, axially pulling each element from only one end thereof so as to reduce the diameter of said element prior to removal from said sheet of nonmagnetic thermoplastic material, and removing said metallic elements to form spaced holes in said sheet, each of said holes being substantially equal in cross section to the cross section of the respective metallic element prior to removal, and being adapted to receive a wire having a coating of magnetic material.
Claim 5
Independent Claim
136 words
A method of making a supporting medium having a plurality of spaced holes and adapted to support within said holes a plurality of wires having a coating of magnetic material, said method comprising the steps of positioning a plurality of metal wires between two sheets of nonmagnetic material, bonding said sheets together about said metal wires to form a laminate, axially pulling each metal wire from only one end thereof so as to reduce the diameter of said wire prior to removal from said laminate, and removing said metal wires from said laminate to form spaced holes in the laminate, each of said holes being substantially equal in cross section to the cross section of the respective metal wire prior to removal, and being adapted to receive and support wires having a coating of magnetic material.
Claim 6
Dependent Claim
31 words
A method of making a supporting medium as in claim 6 wherein each metal wire is coated with a release agent prior to being positioned between the sheets of nonmagnetic material.
