Abstract
Abstract This invention relates to a method of reeling tape and apparatus therefor, particularly to reeling tape apparatus characterized in that the reeling is done while the direction of the width of the tape at the time of travelling and reeling is maintained perpendicular to the floor surface or horizontal plane or base and the tape moves along the floor surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
226 words
Tape reeling apparatus to uniformly wind predetermined segments of very thin, thickness tape on a take-up reel in uniform alignment on the reel core without producing flaccids, wrinkling or crimping of the tape wound on the take-up reel, said apparatus including a first vertically disposed base, a rotatable support means having an axially aligned hub mounted to said first base, a reel of tape adaptable to be mounted on said support means tape payout means including back tensioning means to control the withdrawal of the tape from said tape reel, a second horizontally disposed base adjacent to said first base, guide means on said horizontally disposed base adapted to align the planar width of said tape perpendicular to the surface of said second base and in flush engagement with said second base surface as said tape is moved therealong, said guide means characterized by a plurality of vertically disposed guide rollers adjustably attached to said second base and generally arranged in an alternate fashion to receive the passage of said tape therearound, tape drive means positioned between said rollers to engage and withdraw said tape from said tape reel, and means to selectively adjust the angle of the axis of said rollers relative to said second base surface to provide a predetermined amount of constant downward force on said tape as it passes around said rollers.
Claim 2
Dependent Claim
226 words
Tape reeling apparatus to uniformly wind predetermined segments of very thin, thickness tape on a take-up reel in uniform alignment on the reel core without producing flaccids, wrinkling or crimping of the tape wound on the take-up reel, said apparatus including a first vertically disposed base, a rotatable support means having an axially aligned hub mounted to said first base, a reel of tape adaptable to be mounted on said support means tape payout means including back tensioning means to control the withdrawal of the tape from said tape reel, a second horizontally disposed base adjacent to said first base, guide means on said horizontally disposed base adapted to align the planar width of said tape perpendicular to the surface of said second base and in flush engagement with said second base surface as said tape is moved therealong, said guide means characterized by a plurality of vertically disposed guide rollers adjustably attached to said second base and generally arranged in an alternate fashion to receive the passage of said tape therearound, tape drive means positioned between said rollers to engage and withdraw said tape from said tape reel, and means to selectively adjust the angle of the axis of said rollers relative to said second base surface to provide a predetermined amount of constant downward force on said tape as it passes around said rollers.
Claim 3
Dependent Claim
51 words
The tape reeling apparatus of claim 1 characterized in that said back tensioning means includes a belt brake adapted to engage a portion of said support means hub, said payout means connected through linkage to adjustably apply said brake to maintain a tension on withdrawal of tape from said tape reel.
Claim 4
Dependent Claim
67 words
The tape reeling apparatus of claim 1 characterized by a tape reeling station having a coupling element adapted to receive and releasably engage and rotatably drive an empty reel to take up thereon a predetermined segment of tape, means to grip and draw forward and engage the end of said tape onto said take-up reel core, said tape drive means also adapted to drive Said coupling element.
Claim 5
Dependent Claim
71 words
The tape reeling apparatus of claim 3 characterized by a rotatable cam interconnected to the rotational movement of said tape drive means, switch means operative by said cam indicative of a selected amount of tape passing said tape drive means, and circuit control means connected to said switch means to control said tape drive means to vary the speed of the tape during the reeling operation performed at said reeling station.
Claim 6
Dependent Claim
56 words
The tape reeling apparatus of claim 3 characterized in that said means to grip and draw forward said tape end includes extendable grippers to grip and pull said tape end forward adjacent to said take-up reel core, and laterally extendable tape tension roller positioned to engage and roll said tape end against said take-up reel core.
Claim 7
Dependent Claim
30 words
The tape reeling apparatus of claim 5 characterized by pneumatic nozzle means to direct a jet of air on said tape end as extended forward adjacent said take-up reel core.
Claim 8
Dependent Claim
32 words
The tape reeling apparatus of claim 5 characterized by tape cutting means operative by said switch means through said circuit control means to cut the tape after completion of the reeling operation.
Claim 9
Dependent Claim
95 words
The tape reeling apparatus of claim 3 characterized in that said tape reeling station includes a turn table having four index positions, a concavity at each of said positions to receive an empty take-up reel, means to deposit an empty reel in each concavity as said turn table is rotated prior to said reeling station, said coupling element adapted to move downwardly and engage and rotatably drive an empty take-up reel at said reeling station, and means to engage said take-up reel upon indexing of said turn table after the reeling operation has been completed.
Claim 10
Independent Claim
214 words
The method of reeling predetermined segments of soft and thin tape upon take-up reels in uniform alignment of the reel core without producing flaccids, wrinkling or crimping of the tape wound thereon comprising the steps of aligning the edge of the tape to uniformly move along a planar surface to a tape take-up reeling station, measuring the tape length as it proceeds to the reeling station, gripping the end of the tape and drawing it forward to place the end of the tape in the immediate area of an empty take-up reel at the reeling station, applying a jet of air to the tape end to insure the protrusion of the tape end beyond the take-up reel core, pressing the tape adjacent the tape end against the reel core securing the tape to the take-up reel core, engaging and driving the take-up reel, controlling the rotational speed of the take-up reel, first gradually increasing tape speed, maintaining high tape speed during tape reeling and thereafter gradually decreasing tape speed to completion of tape reeling, synchronizing the rotational speed variation at the reeling station during reeling with the measurement of the desired segment of tape to be placed on the take-up reel, and cutting the tape leading to the reeling station upon completion of reeling.
