Abstract

Abstract This invention relates to a process and apparatus for shirring a sausage casing, which process comprises slipping the casing over a mandrel while maintaining an internal gas pressure in the casing, and compressing the casing against a stop with the formation of pleats, the compressive force being applied to the casing from a plurality of zones rotating to and fro about the mandrel.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 69 words
A process for shirring a sausage casing which comprises slipping the casing over a mandrel while maintaining an internal gas pressure in the casing, and compressing the casing against a stop with the formation of pleats, the compressive force being applied to the casing from a plurality of zones rotating continuously in the direction towards the stop and also rotating to and fro as a unit about the mandrel.
Claim 2
Dependent Claim 69 words
A process for shirring a sausage casing which comprises slipping the casing over a mandrel while maintaining an internal gas pressure in the casing, and compressing the casing against a stop with the formation of pleats, the compressive force being applied to the casing from a plurality of zones rotating continuously in the direction towards the stop and also rotating to and fro as a unit about the mandrel.
Claim 3
Dependent Claim 24 words
A process according to claim 1 in which the compressive force acts at three equally spaced points on the periphery of the sausage casing.
Claim 4
Dependent Claim 12 words
A process according to claim 1 in which the mandrel is stationary.
Claim 5
Independent Claim 77 words
An apparatus for shirring a sausage casing which comprises a mandrel, means for maintaining an internal gas pressure in a casing on the mandrel, a plurality of wheel means rotatable in one direction longitudinally of the mandrel for compressing the casing against a stop with the formation of pleats, the wheel means being uniformly spaced around the mandrel, and means for imparting a to and fro rotational movement to the wheels as a unit about the mandrel.
Claim 6
Independent Claim 77 words
An apparatus for shirring a sausage casing which comprises a mandrel, means for maintaining an internal gas pressure in a casing on the mandrel, a plurality of wheel means rotatable in one direction longitudinally of the mandrel for compressing the casing against a stop with the formation of pleats, the wheel means being uniformly spaced around the mandrel, and means for imparting a to and fro rotational movement to the wheels as a unit about the mandrel.
Claim 7
Dependent Claim 12 words
An apparatus according to claim 4 in which the mandrel is stationary.
Claim 8
Dependent Claim 14 words
An apparatus according to claim 4 in which the wheel means includes three wheels.
Claim 9
Dependent Claim 22 words
An apparatus according to claim 4 in which the to and fro rotational movement of the wheels is effected by eccentric means.
Claim 10
Dependent Claim 15 words
An apparatus according to claim 7 in which the eccentric means has a variable eccentricity.
Claim 11
Dependent Claim 19 words
An apparatus according to claim 4 in which the wheel means are mounted obliquely with respect to the mandrel.
