Abstract

Abstract The Disclosure is directed to a new method of edge marking recordable webs such as audio and/or video tape. A running tape length is initially established between supply and take-up reels. The running path length is intermittently displaced, parallel to the recording surface, which results in a plurality of spaced, concentric, arcuate wrap segments on the take-up reel whose side edges project beyond the side edges of the remainder of the wraps. The side edges of the projecting wrap segments are then marked in any desired manner such as by bringing the same into marking engagement with a printing or marking die whose approach to the wound take-up reel is limited to insure that the non-projecting wraps are not marked.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 75 words
A method of edge marking a recordable tape, comprising: establishing a tape path run onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; steps for offsetting the side edges of at least segments of radially spaced ones of said wraps relative to the remainder of said wraps during the winding thereof; and marking the offset side edges to contrast the remainder of the wound reel.
Claim 2
Independent Claim 75 words
A method of edge marking a recordable tape, comprising: establishing a tape path run onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; steps for offsetting the side edges of at least segments of radially spaced ones of said wraps relative to the remainder of said wraps during the winding thereof; and marking the offset side edges to contrast the remainder of the wound reel.
Claim 3
Dependent Claim 29 words
The method of claim 1 wherein said steps include intermittently displacing said tape path run prior to winding said tape on said reel to produce said offset said edges.
Claim 4
Dependent Claim 31 words
The method of claim 2 including the step of sensing desired marking positions on said tape; and subsequently intermittently displacing said tape path run as a function of sensed marking positions.
Claim 5
Dependent Claim 24 words
The method of claim 2 including the step of intermittently displacing said tape path run as a function of tape movement onto said reel.
Claim 6
Dependent Claim 22 words
The method of claim 2 including the step of intermittently displacing said tape path run as a function of take-up reel rotation.
Claim 7
Dependent Claim 20 words
The method of claim 5 including the step of mechanically translating take-up reel rotation into the intermittent tape path displacement.
Claim 8
Dependent Claim 25 words
The method of claim 2 including the step of limiting the displacement time of said tape path to less the time of one reel revolution.
Claim 9
Independent Claim 74 words
A method of edge marking a reelable web at spaced intervals there along, comprising: establishing a web path run onto a reel; winding said web onto said reel and intermittently displacing at least a portion of said web path run to produce a plurality of radially spaced web offsets on said reel having side edges projecting outwardly of the corresponding said edge of the remainder of said web; and marking said projecting side edges.
Claim 10
Independent Claim 74 words
A method of edge marking a reelable web at spaced intervals there along, comprising: establishing a web path run onto a reel; winding said web onto said reel and intermittently displacing at least a portion of said web path run to produce a plurality of radially spaced web offsets on said reel having side edges projecting outwardly of the corresponding said edge of the remainder of said web; and marking said projecting side edges.
Claim 11
Dependent Claim 21 words
The method of claim 8 including the step of simultaneously contacting all of said projecting side edges with a marking fluid.
Claim 12
Dependent Claim 32 words
The method of claim 9 including the step of preparing a depth of the marking fluid on a flat surface which depth is less than the offset of said spaced web offsets.
Claim 13
Independent Claim 57 words
A method of edge marking a recordable tape, comprising: establishing a tape path run onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; and steps for intermittently offsetting and marking the side edges of said tape to produce marked segments of radially spaced ones of said wraps.
Claim 14
Independent Claim 57 words
A method of edge marking a recordable tape, comprising: establishing a tape path run onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; and steps for intermittently offsetting and marking the side edges of said tape to produce marked segments of radially spaced ones of said wraps.
Claim 15
Independent Claim 90 words
A method of edge marking a recordable tape, comprising: establishing a normal tape path onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; steps for offsetting the side edges of said tape out of said normal tape path and for offsetting the side edges of at least segments of radially spaced ones of said wraps relative to the remainder of said wraps during the winding thereof; and marking the offset side edges to contrast the remainder of the wound reel.
Claim 16
Independent Claim 90 words
A method of edge marking a recordable tape, comprising: establishing a normal tape path onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; steps for offsetting the side edges of said tape out of said normal tape path and for offsetting the side edges of at least segments of radially spaced ones of said wraps relative to the remainder of said wraps during the winding thereof; and marking the offset side edges to contrast the remainder of the wound reel.
Claim 17
Independent Claim 68 words
A method of edge marking a recordable tape, comprising: establishing a tape path run onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; and steps for marking the side edges of said tape with a liquid material to contrast the remainder of said wound reel and for offsetting the side edges on reel relative to the remainder thereof.
Claim 18
Independent Claim 68 words
A method of edge marking a recordable tape, comprising: establishing a tape path run onto a take-up reel; winding said tape on said reel to produce a plurality of wound tape wraps thereon; and steps for marking the side edges of said tape with a liquid material to contrast the remainder of said wound reel and for offsetting the side edges on reel relative to the remainder thereof.
Claim 19
Independent Claim 72 words
A method of edge marking a recordable tape, comprising: establishing a normal tape path onto a take-up reel; winding said tape on said reel to produce a tape pancake having a plurality of wound tape wraps thereon; and steps for producing a plurality of offset edge marked tape wrap segments on the pancake including intermittently offsetting the tape out of the normal tape path and marking the side edges of said tape.
Claim 20
Independent Claim 72 words
A method of edge marking a recordable tape, comprising: establishing a normal tape path onto a take-up reel; winding said tape on said reel to produce a tape pancake having a plurality of wound tape wraps thereon; and steps for producing a plurality of offset edge marked tape wrap segments on the pancake including intermittently offsetting the tape out of the normal tape path and marking the side edges of said tape.
