Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
An apparatus for accurately indicating predetermined, measured, equal lengths of tubular casing to be contained in shirred casing sticks comprising in combination; a. a supported hollow mandrel having shirring means mounted about a portion thereof; b. means for advancing a continuous length of tubular casing onto said mandrel and through said shirring means; c. an indicator slidably mounted on a guide rod positioned spacedly adjacent to and extending parallel with the longitudinal axis of said hollow mandrel; d. means for indexing said indicator at a set point on a portion of the advancing casing emerging from said shirring means denoting a predetermined length of casing having advanced to and through said shirring means; e. means for advancing said casing from said shirring means over said mandrel with said indicator indexed thereon and freely advancing therewith; and f. means for disengaging said indicator from said casing after a subsequent portion of a predetermined length of casing emerges from said shirring means.
Claim 2
Independent Claim
160 words
An apparatus for accurately indicating predetermined, measured, equal lengths of tubular casing to be contained in shirred casing sticks comprising in combination; a. a supported hollow mandrel having shirring means mounted about a portion thereof; b. means for advancing a continuous length of tubular casing onto said mandrel and through said shirring means; c. an indicator slidably mounted on a guide rod positioned spacedly adjacent to and extending parallel with the longitudinal axis of said hollow mandrel; d. means for indexing said indicator at a set point on a portion of the advancing casing emerging from said shirring means denoting a predetermined length of casing having advanced to and through said shirring means; e. means for advancing said casing from said shirring means over said mandrel with said indicator indexed thereon and freely advancing therewith; and f. means for disengaging said indicator from said casing after a subsequent portion of a predetermined length of casing emerges from said shirring means.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein the set point at which indicator is indexed in the shirred casing is at the last formed pleat in each successive predetermined, measured length of shirred casing.
Claim 4
Dependent Claim
31 words
The apparatus of claim 1 wherein the set point to which the indicator is indexed is adjacent the locus where the continuous length of tubular casing emerges from the shirring means.
Claim 5
Dependent Claim
31 words
The apparatus of claim 1 wherein at least two indicators are provided to be successively indexed at the set point on successive equal lengths of casing emerging from the shirring means.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1 which includes means for compacting said advancing shirred with said indicator indexed thereon and freely advancing therewith.
Claim 7
Dependent Claim
17 words
The apparatus of claim 1 wherein said indicator is slidably mounted on a rotatable, splined guide rod.
Claim 8
Independent Claim
163 words
A method for obtaining shirred casing sticks which contain predetermined, measured equal lengths of tubular casing, said method including the steps of: a. continuously advancing a continuous length of tubular casing about a hollow mandrel and through a shirring passage; b. at a set point where the casing emerges from said shirring passage indexing an indicator on the advancing tubular casing after a predetermined length of casing emerges from the shirring passage; c. continuously advancing said continuous length of tubular casing from said shirring passage and over said mandrel with said indexed indicator freely advancing concurrently with the casing until a subsequent predetermined length of shirred casing has advanced through said shirring passage; d. disengaging said indicator from said shirred casing and returning said indicator to set point at the exit of said shirring passage; and e. indexing said indicator on a successive section of casing emerging from said shirring passage such that a predetermined, measured length of advancing Shirred casing is indicated.
Claim 9
Independent Claim
163 words
A method for obtaining shirred casing sticks which contain predetermined, measured equal lengths of tubular casing, said method including the steps of: a. continuously advancing a continuous length of tubular casing about a hollow mandrel and through a shirring passage; b. at a set point where the casing emerges from said shirring passage indexing an indicator on the advancing tubular casing after a predetermined length of casing emerges from the shirring passage; c. continuously advancing said continuous length of tubular casing from said shirring passage and over said mandrel with said indexed indicator freely advancing concurrently with the casing until a subsequent predetermined length of shirred casing has advanced through said shirring passage; d. disengaging said indicator from said shirred casing and returning said indicator to set point at the exit of said shirring passage; and e. indexing said indicator on a successive section of casing emerging from said shirring passage such that a predetermined, measured length of advancing Shirred casing is indicated.
Claim 10
Dependent Claim
38 words
The method of claim 7 wherein the point at which the indicator is indexed on the tubular casing emerging from the shirring passage is at the last formed pleat in each successive, predetermined, measured length of shirred casing.
Claim 11
Dependent Claim
11 words
The method of claim 7 wherein the tubular casing is collagen.
Claim 12
Dependent Claim
32 words
The method of claim 7 which includes the step of severing the advancing shirred casing at the point where the indicator is indexed before disengaging said indexed indicator from said shirred casing.
