Definitions

  • My invention relates to a method for manufacturin cores for cables for communica- 5 tion circuits.
  • Fig. 3 may also be increased gradually to a certain limit and then decreased again gradually, as shown in Fig. 3. It is also possible, as shown in Fig. 5, to wind on one core, two cords running parallel at, for instance, a distance of 7 mm., for example with a total pitch of 14 mm., and on another core only one cord with a pitch of 7 mm. In this case the cores with 'two cords have about more paper, but as shown by experience this greater quantity of paper is of no great consequence for the value of the capacitance.
  • the capacitance can be equalized by making the diameter of the cores with ,two cords larger than that of the cores with one cord, for example, by pasing the cores with two cords through a somewhat wider shaping die than thecores with one cord.
  • it is advantageous to-arrange these cores so that the cores with one cord form one pair and those with twocords the-other pair of thequad.
  • a telephone cable having a plurality of insulated strands, each strand consisting of a core conductor, paper cord wound upon said conductor and paper tape spirally wound over the cord winding, adjacently located cord winding turns of adjacent cable strands having the same winding direction but difierent total itch.
  • a telephone cable having a plurality of insulated strands, each strand consisting of a core conductor, paper cord wound upon said conductor and paper tape spirally wound over the cord winding, adjacently located cord winding turns of adjacent cable strands having the same winding direction but different pitch, at least one of two adjacent strands having its cord winding laid with successive turns of unequal pitch.
  • a telephone cable having a plurality of insulated strands, each strand consisting of a core conductor, paper cord wound uponsaid conductor and paper tape spirally wound over the cord winding, ad acently located cord winding turns of adjacent cable strands having the same winding direction but different pitch, at least one of two adjacent strands having its cord winding laid with entirely irregular pitch.
  • a telephone cable having a plurality I of insulated strands, each strand consisting of a core conductor, paper cord. wound upon said conductor and paper tape spirally wound over the cord winding, adjacently located cord winding turns of adjacent cable strands having the same winding direction but different pitch, at least one of two adjacent strands having its cord winding laid with periodically varying pitch.
  • telephone cable having a plurality of insulated strands, each strand consisting of a core conductor, paper cord wound upon said conductor and paper tape spirally wound over the cord winding, adjacently located cord winding turns of adjacent cable strands having the same winding direction but different pitch, at least one of two adjacent strands having its cord winding laid with varyin itch between adjacent turns, which gradua ly varies over the length of the strand from a minimum pitch at least once to a maximum and back to a minimum.
  • a telephone cable having a plurality of insulated strands, each strand consisting of a core conductor, paper'cord wound upon said conductor and paper tape spirally wound over the cord winding, adjacently located cord winding turns of adjacent cable strands having the same winding direction
