Abstract

864,836. Winding coils; electric coils. ERICSSON TELEPHONES Ltd. Sept. 4, 1958 [Sept. 7, 1957], No. 28296/57. Class 35. A self - supporting coil, especially a very small discshaped coil 5, is formed by winding insulated wire into an annular groove 3 in a mandrel 1, treating the coil to bond the turns together, then breaking the neck 4 of the mandrel to remove the portion 2 and thus release the coil. The mandrel may be of ductile metal and the wire may be treated with a thermo-plastic bonding agent before or after winding and the turns subsequently bonded by heating. A driving and pick-off coil, for magnetostrictive delay line systems, made by this method, has an axial length of ten-thousandths of an inch and a central bore of fifteenthousandths of an inch, the mandrel being formed from “-inch diameter brass rod and 400 turns of 0.0016 inch diameter thermo-plastic resin coated wire being used.
