Abstract
Abstract Flexible, tubular and inflatable sausage casings are cleanly severed during continuous shirring operations without formation of troublesome loose tab-ends by impinging thin, high pressure, high velocity water jet(s) against casing sidewall. Severing may be performed over a shirring mandrel without damage to the same.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
87 words
A method of severing a tubular food casing during a shirred process, said method comprising the steps of mounting at least a portion of the casing on a shirring mandrel where said casing is inflated, and impinging a plurality of high pressure streams of aqueous liquid against said casing in planes which are transverse to the longitudinal axis of the casing while moving the streams laterally or rotationally about the axis of the casing, said streams simultaneously severing said casing at multiple locations without striking the mandrel.
Claim 2
Independent Claim
87 words
A method of severing a tubular food casing during a shirred process, said method comprising the steps of mounting at least a portion of the casing on a shirring mandrel where said casing is inflated, and impinging a plurality of high pressure streams of aqueous liquid against said casing in planes which are transverse to the longitudinal axis of the casing while moving the streams laterally or rotationally about the axis of the casing, said streams simultaneously severing said casing at multiple locations without striking the mandrel.
Claim 3
Dependent Claim
19 words
The method of claim 1, including the step of rotating the streams reciprocally about the axis of the casing.
Claim 4
Independent Claim
79 words
A method of severing a tubular food casing during a shirring process, said method comprising the steps of mounting at least a portion of the casing on a shirring mandrel where said casing is inflated, and impinging a high pressure stream of aqueous liquid against said casing in a plane which is transverse to the longitudinal axis of the casing while rotating the stream about the axis of the casing, said stream severing the casing without striking the mandrel.
Claim 5
