Method for applying coded labels to cable
View Patent ↗Flexible indicia bearing labels are placed on armored electrical cable at spaced apart intervals while the cable is being moving continuously from an armoring station to a takeup reel or accumulator. A label dispenser places labels in a U shaped recess of a body which is moveable toward engagement with the cable. Opposed rollers fold one edge of the label over into engagement with the surface of the cable and the other edge of the label over onto itself in overlapping relationship. The cable is passed through a heat tunnel to shrink the labels into tight engagement with the cable. A controller monitors movement of the cable and controls actuators for applying and folding labels onto the cable at spaced apart intervals.
1. A method for labeling armored electrical cable between an armoring station for said cable and a takeup reel for storage of said cable, the cable having an outermost sheath with convolutions defining alternating peaks and valleys, the method comprising the steps of:
applying, using a machine, a plurality of separate labels having a label substrate with an attaching side and an opposed indicia side, to the outermost sheath of the armored electrical cable such that the attaching side contacts the outermost sheath, each separate label being applied circumferentially to said cable at spaced apart points on said cable while said cable traverses between said armoring station and said takeup reel, the labels being applied to contact the outermost sheath for substantially the entirety of the label and to cover at least one peak of the convolutions of the outermost sheath.
2. The method set forth in claim 1 , including the step of:
providing indicia on said labels indicating one of a physical characteristic of said cable and an electrical characteristic of said cable.
3. The method set forth in claim 2 , wherein:
indicia is provided identifying a wire gauge size of said cable.
4. The method set forth in claim 3 , wherein:
indicia is provided indicating an electrical performance specification of said cable.
5. The method set forth in claim 1 , including the step of:
providing an adhesive surface on said labels opposite respective sides of said labels having indicia thereon;
placing said labels in contact with said cable; and
folding opposed edges of said labels over into engagement with a surface of said cable and a surface of said label, respectively.
6. The method set forth in claim 5 wherein:
said labels are placed in contact with said cable while said cable traverses substantially linearly and continuously between said armoring station and said takeup reel.
7. A method for labeling metal clad armored electrical cable comprising plural elongated electrical conductors having a metal armoring strip wrapped thereover in helical convolutions to form an outermost circumferential metal cladding having repeated peaks and valleys along the length of said cable, said method being carried out by placing labels, the labels having a substrate with an attaching side and an opposed indicia side, to an exterior surface of said outermost metal cladding at spaced apart intervals between an armoring station wherein said metal strip is applied over said conductors and a takeup reel for said cable, comprising the steps of:
placing said labels circumferentially around said metal cladding at spaced apart intervals of said cable while said cable is moving continuously between said armoring station and said takeup reel, the labels being applied such that the attaching side is oriented and attached to the outermost metal cladding for substantially the entirety of the label and adhering said labels tightly to said cable on an exterior surface of said metal cladding; and
wherein each of said labels is non-conductive and circumferentially covers at least one respective peak of the metal cladding.
8. The method set forth in claim 7 , including the step of:
placing indicia on said labels, respectively, indicating one of a physical characteristic of said cable and an electrical characteristic of said cable.
9. The method set forth in claim 7 , including the step of:
providing an adhesive surface on said labels respectively, for adhering said labels to said cable while said cable moves continuously.
10. The method set forth in claim 9 , including the step of:
folding opposed edges of said labels over onto said exterior surface and onto said labels, respectively, to apply said labels circumferentially to said cable.
11. The method set for in claim 10 , including the step of:
further treating said labels to adhere said labels tightly to said cable.
12. The method set forth in claim 11 , including the step of:
heating said labels to shrink said labels into tight engagement with said cable.
13. The method of claim 7 wherein placing said labels further comprises applying said labels using a machine.
14. The method of claim 7 wherein placing said labels further comprises slightly overlapping opposed edges of the label body.
15. The method of claim 1 wherein opposed edges of said label body slightly overlap one another.
16. The method of claim 7 further comprising at least partially conforming said labels to the peaks and valleys of said metal cladding.
