Abstract
A novel apparatus and operational system for the improved waterproofing impregnation of an already stranded core of communication cable and the like with a jelly-like waterproofing compound by the application of vibratory energy is disclosed. The vibrational forces imparted to the jelly-like waterproofing compound enables such to more completely and/or more quickly penetrate the interstices of such stranded core.
Claims7
A method of waterproofing a core of a communication cable, wherein the core is defined by a plurality of bundled individual material strands that are located in relatively close adjacent parallel relation, comprising the steps of continuously advancing said core through an enclosed filling chamber, directing a jelly-like waterproofing compound in at least a semi-fluid state under pressure into said chamber and in substantially complete enveloping contact with the outer surfaces of said continuously advancing core, and directly vibrating said compound by vibrating means located within said chamber in contact with said compound while maintaining said strands in the relatively close, adjacent parallel relation, wherein said compound is forced between said strands to fill the interstices therebetween, thereby completely waterproofing said strands.
Apparatus for waterproofing a core of a communication cable with a jelly-like waterproofing compound wherein the core is defined by a plurality of bundled individual material strands that are located in relatively close adjacent, parallel relation, comprising a substantially elongated, longitudinally oriented filling chamber having entrance and exit portions for the continuous movements of said cable through said chamber, a supply source for said compound located exteriorly of said chamber, a pump for directing said compound from said supply source into said chamber for complete enveloping contact with said cable passing through said chamber and for maintaining said compound under pressure in said chamber, and means for vibrating said compound in said chamber for causing said compound to penetrate into and fill the interstices between individual material strands of said core for the effective waterproofing thereof, said vibrating means including a plurality of transducers that are located interiorly of said chamber in direct contact with said compound and in spaced, substantially radial disposition with respect to said core.
