Abstract

Abstract A rotatable assembly is rotatably mounted on a stationary assembly. The stationary assembly guides a conductor wire, or the like, to a wrapping station, the rotatable assembly applying glue or other adhesive to a portion of a wrapping tape which is wrapped around the conductor wire at the wrapping station. The glue is applied to the wrapping tape by supplying it to a receptacle in the rotatable assembly, from which it is forced out through a hole by centrifugal force. The receptacle is of conical shape so that the centrifugal force acting on the glue will have a component thereof forcing the glue up toward the hole, and out therefrom.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 116 words
An apparatus for gluing a wrapping tape on an elongate article comprising: means for continuously feeding an elongate article through tubular means; a stationary assembly coaxial with said tubular means; a rotatable assembly rotatable about said stationary assembly; means for rotatably mounting said rotatable assembly on said stationary assembly; and means for supplying glue or other adhesive to said stationary assembly, said stationary assembly having means for feeding the adhesive to said rotatable assembly, said rotatable assembly having means for receiving the adhesive from said stationary means and having means for coating a strip of the adhesive onto a portion of a wrapping tape and rotatable means for wrapping the coated tape onto said elongate article.
Claim 2
Independent Claim 116 words
An apparatus for gluing a wrapping tape on an elongate article comprising: means for continuously feeding an elongate article through tubular means; a stationary assembly coaxial with said tubular means; a rotatable assembly rotatable about said stationary assembly; means for rotatably mounting said rotatable assembly on said stationary assembly; and means for supplying glue or other adhesive to said stationary assembly, said stationary assembly having means for feeding the adhesive to said rotatable assembly, said rotatable assembly having means for receiving the adhesive from said stationary means and having means for coating a strip of the adhesive onto a portion of a wrapping tape and rotatable means for wrapping the coated tape onto said elongate article.
Claim 3
Dependent Claim 67 words
The apparatus according to claim 1 wherein said rotatable assembly comprises a first part having a first and second end mounted concentrically about said stationary assembly, and a second part having a first end fixedly connected to said second end of said first part and mounted concentrically about said stationary assembly, said second part extending along said stationary portion from said second end of said first part.
Claim 4
Dependent Claim 34 words
The apparatus according to claim 2 wherein said means for rotatably mounting said rotatable assembly about said stationary assembly comprises bearings mounted about said stationary assembly near said first end of said first part.
Claim 5
Dependent Claim 50 words
The apparatus according to claim 1 wherein said stationary assembly comprises a first tube extending longitudinally through said rotatable assembly, and a second tube mounted coaxial within said first tube for guiding the article there along, said first and second tubes forming an annular channel therebetween along the length thereof.
Claim 6
Dependent Claim 63 words
The apparatus according to claim 4 wherein said means for feeding the adhesive comprises an inlet tube connecting said means for supplying the adhesive with said annular channel, and a disc fixedly mounted to said first tube, said disc having at least one formed therein communicating with said annular channel and leading to said means for receiving the adhesive of said rotatable assembly.
Claim 7
Dependent Claim 68 words
The apparatus according to claim 5 wherein said rotatable assembly comprises a first part having a first and a second end mounted concentrically about said stationary assembly, and a second part having a first end fixedly connected to said second end of said first part and mounted concentrically about said stationary assembly, said second part extending along said stationary portion from said second end of said first part.
Claim 8
Dependent Claim 71 words
The apparatus according to claim 6 wherein said means for receiving the adhesive from said means for feeding comprises a receptacle formed in said second part near said first end, said disc being mounted on said first tube at a position near said first end, said disc being mounted directly above said receptacle so that as the adhesive exits from said at least one opening, it will fall into said receptacle.
Claim 9
Dependent Claim 12 words
The apparatus according to claim 7 wherein said receptacle is conically shaped.
Claim 10
Dependent Claim 90 words
The apparatus according to claim 8 wherein said means for applying a strip of adhesive onto a portion of a wrapping tape comprises a ring mounted between said first end of said second part and said second end of said first part, said ring having an opening formed on the circumference thereof, said second part of said rotatable assembly having an opening for the communication of said opening in said ring with the outside of said apparatus for applying the adhesive to a wrapping tape in contact with said opening.
Claim 11
Dependent Claim 70 words
The apparatus according to claim 2 wherein said first part is of stepped cylindrical shape, said second end of said first part having threads formed on the circumference thereof, and said second part is of part cylindrical and part conical shape, said first end of said second part having threads formed in the inner circumference thereof for mating engagement with the threads of said second end of said first part.
Claim 12
Dependent Claim 64 words
The apparatus according to claim 10 wherein said means for rotatably mounting said rotatable assembly on said stationary assembly comprises a shaft concentrically mounted about said stationary assembly for rotation relative thereto, said shaft having a first end connected to a cylindrical portion of said second part, and a second end extending from said second part in a direction away from said second part.
Claim 13
Dependent Claim 87 words
The apparatus according to claim 1 wherein said means for supplying glue or other adhesive to said rotatable assembly comprises drop-equipment positioned near said stationary assembly and above said means for receiving the adhesive, a liquid column of said adhesive having a first end connected to said drop-equipment, and a valve having a first and a second end, said liquid column having a second end connected to said first end of said valve, said second end of said valve connected to said means for feeding the adhesive.
Claim 14
Dependent Claim 47 words
The apparatus according to claim 1 further comprising means for rotatably mounting a roll of wrapping tape about said stationary assembly, said means for rotatably mounting the wrapping tape mounting said wrapping tape to rotate about an axis coextensive with the longitudinal axis of said stationary assembly.
Claim 15
Dependent Claim 41 words
The apparatus according to claim 13 wherein said rotatable assembly comprises means for guiding the wrapping tape from the roll, said means for guiding the wrapping tape guiding the wrapping tape past said means for applying a strip of the adhesive.
Claim 16
Dependent Claim 34 words
The apparatus according to claim 13 further comprising means mounted above said rotatable assembly for wrapping the wrapping tape onto the article and for sensing whether adhesive has been applied to the wrapping tape.
