Abstract
Abstract A controlled friction tape roller for a tape transport system for reel to reel operations is described. A controlled friction tape roller is arranged adjacent a tape reel to introduce a high tension in the tape extending between the reel and the controlled friction roller to allow the tape to be more tightly wound or packed on the reel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
In a tape transport system including at least a single rotatable tape storage reel having tape extending therefrom to be wound from a tape source and unwound therefrom, means for driving the storage reel to transfer tape thereto from the tape source, tensioning means coupled to the tape adjacent the storage reel for increasing the tension of the tape extending between the storage reel and said tensioning means whereby the tape wound on the reel is tightly wound thereon, said tensioning means comprising a rotatable drum and braking means arranged coaxially therewith for providing a preselected amount of drag for the drum and being arranged to be normally operative, and means for selectively rendering the braking means inoperative.
Claim 2
Dependent Claim
118 words
In a tape transport system including at least a single rotatable tape storage reel having tape extending therefrom to be wound from a tape source and unwound therefrom, means for driving the storage reel to transfer tape thereto from the tape source, tensioning means coupled to the tape adjacent the storage reel for increasing the tension of the tape extending between the storage reel and said tensioning means whereby the tape wound on the reel is tightly wound thereon, said tensioning means comprising a rotatable drum and braking means arranged coaxially therewith for providing a preselected amount of drag for the drum and being arranged to be normally operative, and means for selectively rendering the braking means inoperative.
Claim 3
Dependent Claim
118 words
In a tape transport system including at least a single rotatable tape storage reel having tape extending therefrom to be wound from a tape source and unwound therefrom, means for driving the storage reel to transfer tape thereto from the tape source, tensioning means coupled to the tape adjacent the storage reel for increasing the tension of the tape extending between the storage reel and said tensioning means whereby the tape wound on the reel is tightly wound thereon, said tensioning means comprising a rotatable drum and braking means arranged coaxially therewith for providing a preselected amount of drag for the drum and being arranged to be normally operative, and means for selectively rendering the braking means inoperative.
Claim 4
Dependent Claim
118 words
In a tape transport system including at least a single rotatable tape storage reel having tape extending therefrom to be wound from a tape source and unwound therefrom, means for driving the storage reel to transfer tape thereto from the tape source, tensioning means coupled to the tape adjacent the storage reel for increasing the tension of the tape extending between the storage reel and said tensioning means whereby the tape wound on the reel is tightly wound thereon, said tensioning means comprising a rotatable drum and braking means arranged coaxially therewith for providing a preselected amount of drag for the drum and being arranged to be normally operative, and means for selectively rendering the braking means inoperative.
Claim 5
Dependent Claim
34 words
In a tape transport system as defined in claim 1 wherein the rotatable drum is adapted to normally prevent the tape advancing thereby from slipping thereover and rotating the drum against said braking means.
Claim 6
Dependent Claim
174 words
In a reel to reel tape transport system for transferring tape from one storage reel to another storage reel including a pair of rotatable tape storage reels mounted in a spaced apart relationship and having tape extending between the reels, means for driving each of the storage reels to transfer tape between the reels, tape guide means mounted adjacent each of the reels and engaging the tape extending between the reels for maintaining a preselected amount of tension on the tape, tape tensioning means arranged between the tape guide means and at least one of the storage reels for increasing the tape tension of the tape extending between said one reel and the tape tensioning means whereby when said one reel functions as a tape take-up reel the tape is tightly wound thereon, said tensioning means comprising a rotatable drum and braking means arranged coaxially therewith for providing a preselected amount of drag for the drum with the braking means arranged to be normally operative, and mEans for selectively rendering the braking means inoperative.
Claim 7
Dependent Claim
174 words
In a reel to reel tape transport system for transferring tape from one storage reel to another storage reel including a pair of rotatable tape storage reels mounted in a spaced apart relationship and having tape extending between the reels, means for driving each of the storage reels to transfer tape between the reels, tape guide means mounted adjacent each of the reels and engaging the tape extending between the reels for maintaining a preselected amount of tension on the tape, tape tensioning means arranged between the tape guide means and at least one of the storage reels for increasing the tape tension of the tape extending between said one reel and the tape tensioning means whereby when said one reel functions as a tape take-up reel the tape is tightly wound thereon, said tensioning means comprising a rotatable drum and braking means arranged coaxially therewith for providing a preselected amount of drag for the drum with the braking means arranged to be normally operative, and mEans for selectively rendering the braking means inoperative.
Claim 8
Dependent Claim
34 words
In a tape transport system as defined in claim 3 wherein the rotatable drum is adapted to normally prevent the tape advancing thereby from slipping thereover and rotating the drum against said braking means.
Claim 9
Dependent Claim
43 words
In a reel to reel tape transport system as defined in claim 3 including and means for selectively controlling the amount of force required to rotate the roller by the tape advanced thereby whereby the amount of tension on the tape is controlled.
Claim 10
Dependent Claim
182 words
In a reel to reel tape transport system for transferring tape from one storage reel to another storage reel including a pair of rotatable tape storage reels mounted in a spaced apart relationship and having tape extending between the reels, means for driving each of the storage reels to transfer tape between the reels, tape guide means mounted adjacent each of the reels and engaging the tape extending between the reels for maintaining a preselected amount of tension on the tape, tape tensioning means arranged between the tape guide means and at least one of the storage reels for increasing the tape tension of the tape extending between said one reel and the tape tensioning means whereby when said one reel functions as a tape take-up reel the tape is tightly wound thereon, said tape tensioning means comprising a friction brake for controlling the drag on the roller and means for adjusting the braking force applied by the brake to thereby control the drag, said brake being arranged to normally apply said braking force, and means for selectively releasing the braking force.
Claim 11
Dependent Claim
182 words
In a reel to reel tape transport system for transferring tape from one storage reel to another storage reel including a pair of rotatable tape storage reels mounted in a spaced apart relationship and having tape extending between the reels, means for driving each of the storage reels to transfer tape between the reels, tape guide means mounted adjacent each of the reels and engaging the tape extending between the reels for maintaining a preselected amount of tension on the tape, tape tensioning means arranged between the tape guide means and at least one of the storage reels for increasing the tape tension of the tape extending between said one reel and the tape tensioning means whereby when said one reel functions as a tape take-up reel the tape is tightly wound thereon, said tape tensioning means comprising a friction brake for controlling the drag on the roller and means for adjusting the braking force applied by the brake to thereby control the drag, said brake being arranged to normally apply said braking force, and means for selectively releasing the braking force.
