Abstract
Abstract Plastic covered coils which are compact and easily inserted in a circuit board are efficiently and economically produced by a continuous production method wherein a generally tubular core having a winding thereon is plugged onto a mounting rod portion of a transporting belt and has the coil ends connected to a upper portion of the belt, a coating of plastic is applied over the coil sub-assembly, the upper discontinuous portion of the band is separated from the lower continuous portion, and the contacts formed as required. An enlarged base formed by the plastic coating may contain coil control components.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
A method for the substantially continuous production in series of a generally elongated coil means having first and second ends, said first end including a base means having contact means thereon comprising the steps of winding onto a tubular core a plurality of turns of at least one wire, said wire having a first end and a second end, positioning one end of the wire winding so that it extends through the tubular core whereby said first and second ends of the wire winding are at said first end of said tubular core, mounting this tubular wire wound core on a projecting portion of a transporting belt means, said belt means having an outer portions which, when separated therefrom, serve as first and second contact means, connecting said first and second wire ends to separate ones of said contact means, applying a coating generally over the surface of said coil means except for portions of said contact means, and separating said outer portions of said transporting belt means from the remainder of said belt to form said coil means.
Claim 2
Independent Claim
179 words
A method for the substantially continuous production in series of a generally elongated coil means having first and second ends, said first end including a base means having contact means thereon comprising the steps of winding onto a tubular core a plurality of turns of at least one wire, said wire having a first end and a second end, positioning one end of the wire winding so that it extends through the tubular core whereby said first and second ends of the wire winding are at said first end of said tubular core, mounting this tubular wire wound core on a projecting portion of a transporting belt means, said belt means having an outer portions which, when separated therefrom, serve as first and second contact means, connecting said first and second wire ends to separate ones of said contact means, applying a coating generally over the surface of said coil means except for portions of said contact means, and separating said outer portions of said transporting belt means from the remainder of said belt to form said coil means.
Claim 3
Dependent Claim
41 words
A method according to claim 1 wherein said transporting belt means comprises two generally parallel and spaced first and second portions, said second portion of said belt having a mounting rod projection received in said second end of said tubular core.
Claim 4
Dependent Claim
72 words
A method according to claim 2 wherein said second portion of said transporting belt means additionally contains mounting supports spaced between adjacent mounting rod projections, said mounting supports having a circular portion receiving therein an unwound tubular core, said unwound tubular core lying between adjacent coil means in generally parallel relationship thereto, and said method includes the step of separating said mounting support from said second portion of said transporting belt means.
Claim 5
Dependent Claim
91 words
A method according to claim 3 wherein said belt second portion has a generally T-shaped member consisting of a leg and a cross member extending therefrom, said T-shape member being attached to said second portion by the leg of said T-shaped member, said method including the steps of bending said cross member of said T-shape member into a generally circular shaped portion, and bending said leg at right angles whereby said leg serves as a stop for said unwound core when said unwound core is inserted in said circular shaped portion.
Claim 6
Dependent Claim
59 words
A method according to claim 1 wherein said coil is generally cylindrically shaped, said first end of said coil including an enlarged base portion having first and second lateral projections, said projections being of a different width and being less than a diameter of said cylindrical portion, said first and second projections being adjacent each of said contact means.
Claim 7
Dependent Claim
45 words
A method according to claim 1 wherein said contact means when separated from said belt means, has a portion thereof bent at a right angle thereto whereby said bent portion may serve as a stop means when said coil is plugged in a circuit board.
Claim 8
Dependent Claim
42 words
A method according to claim 1 including providing saId projecting portion of said transporting belt means with and internal slit dividing said projecting portion into a first and a second part, and bending said first and second parts away from each other.
Claim 9
Dependent Claim
19 words
A method according to claim 5 including the step of embedding component coil control elements in said lateral projections.
