Abstract
Abstract An apparatus and method is disclosed for wrapping a bundle of spliced wires to create a waterproof insulating cover for the splice, in which a segment of autogenous tape is fed over a cradle fixture prior to positioning the wire bundle thereover. Oppositely positioned hinged portions of wrapping members are each sequentially advanced to successively engage and fold each end of the tape segment over the wire bundle, each member cammed as it is advanced plunging down to press the tape end over the wire bundle. A pressure platen is advanced down onto the wrapped bundle to band the lapped tape portions together, with a relief cavity preventing undue thinning of the tape in the region of the uninsulated wire splice.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
Apparatus for wrapping a bundle of wires comprising: tape supply means for feeding segments of wrapping tape; a cradle fixture adapted to receive a segment of tape from said tape supply means, said cradle fixture including guide means for positioning said bundle of wires across said tape segment; a pair of oppositely directed wrapping members mounted for in and out movement on either side of said cradle fixture, in a direction transverse to said wire bundle in said cradle fixture and generally aligned with said tape segment; actuator means for powered sequential movement of each of said wrapping members inwardly toward said wire handle; each of said wrapping members having an engagement portion located to engage a respective end of said tape segment as a respective wrapping member is advanced inwardly; each of said wrapping member engagement portion being hinged to be able to be moved downwardly; and cam means causing said downward movement as said wrapping member is advanced inwardly to cause plunging motion thereof to compress said tape as each of said tape ends is wrapped over said wire bundle.
Claim 2
Dependent Claim
182 words
Apparatus for wrapping a bundle of wires comprising: tape supply means for feeding segments of wrapping tape; a cradle fixture adapted to receive a segment of tape from said tape supply means, said cradle fixture including guide means for positioning said bundle of wires across said tape segment; a pair of oppositely directed wrapping members mounted for in and out movement on either side of said cradle fixture, in a direction transverse to said wire bundle in said cradle fixture and generally aligned with said tape segment; actuator means for powered sequential movement of each of said wrapping members inwardly toward said wire handle; each of said wrapping members having an engagement portion located to engage a respective end of said tape segment as a respective wrapping member is advanced inwardly; each of said wrapping member engagement portion being hinged to be able to be moved downwardly; and cam means causing said downward movement as said wrapping member is advanced inwardly to cause plunging motion thereof to compress said tape as each of said tape ends is wrapped over said wire bundle.
Claim 3
Dependent Claim
51 words
The apparatus according to claim 1 further including a pressure platen positioned over said cradle fixture and movable up and down in alignment with the center of said wire bundle and said tape segment, said pressure platen including a portion moved to compress a wrapped wire bundle in said cradle fixture.
Claim 4
Dependent Claim
28 words
The apparatus according to claim 2 wherein said pressure platen is formed with a relief cavity limiting compression of said wrapped wire bundle in the central region thereof.
Claim 5
Dependent Claim
29 words
The apparatus according to claim 1 wherein said tape supply means supplies autogenous tape having one surface welding to itself when brought into mutual contact with another tape surface.
Claim 6
Dependent Claim
34 words
The apparatus according to claim 1 wherein each of said wrapping members is urged to the up position by torsion spring means overcome by said cam means upon advance inward of said wrapping member.
Claim 7
Dependent Claim
54 words
The apparatus according to claim 1 wherein said tape supply means advances said tape segment over the downwardly inclined top surface of one of said wrapping members in the in and down position to thereby be ramped up by contact with said wrapping member as said tape segment is advanced across said cradle fixture.
Claim 8
Dependent Claim
45 words
The apparatus according to claim 4 wherein said tape supply means includes a reel of said autogenous tape and means mounting said reel in a horizontal position and guiding said tape from said horizontal reel to be twisted to lie horizontal in said cradle fixture.
Claim 9
Independent Claim
176 words
A method of wrapping a bundle of insulated wires having an uninsulated splice located at an intermediate location along the length of said bundle, comprising the steps of: feeding a segment of wrapping tape to lie flat and lengthwise across a wrapping cradle fixture; positioning said wire bundle across said tape segment with said splice centrally disposed; advancing a first wrapping member from one end of said tape segment so as to engage said end with a portion thereof and fold the same across said wire bundle; moving said portion downwardly as advancing to plunge to press said tape end against said wire splice after folding the same; advancing a second wrapping member from the other end of said tape segment so as to engage said other end with a portion thereof so as to fold said other end back across said wire bundle, moving said portion downwardly as advanced so as to plunge to press said other tape segment end over said wire bundle and previously wrapped tape segment end, thereby wrapping said wire bundle.
Claim 10
Independent Claim
176 words
A method of wrapping a bundle of insulated wires having an uninsulated splice located at an intermediate location along the length of said bundle, comprising the steps of: feeding a segment of wrapping tape to lie flat and lengthwise across a wrapping cradle fixture; positioning said wire bundle across said tape segment with said splice centrally disposed; advancing a first wrapping member from one end of said tape segment so as to engage said end with a portion thereof and fold the same across said wire bundle; moving said portion downwardly as advancing to plunge to press said tape end against said wire splice after folding the same; advancing a second wrapping member from the other end of said tape segment so as to engage said other end with a portion thereof so as to fold said other end back across said wire bundle, moving said portion downwardly as advanced so as to plunge to press said other tape segment end over said wire bundle and previously wrapped tape segment end, thereby wrapping said wire bundle.
Claim 11
Dependent Claim
35 words
The method according to claim 8 wherein autogenous tape is used to wrap said wire bundle, and further including the step of compressing said wrapped wire bundle to bond said wrapped tape segment to itself.
Claim 12
Dependent Claim
31 words
The method according to claim 9 wherein in said compressing step, a localized central region around said splice is not compressed to prevent thinning of said tape segment over said splice.
