Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
49 words
A process for multi-direction orienting of a malleable film which comprises pulling a malleable film through the bite between at least one pair of cooperating multi-directional orientation rollers having interengaging surface portions thereby imparting a random orientation to the molecular structure of said film during passage between said rollers.
Claim 2
Dependent Claim
49 words
A process for multi-direction orienting of a malleable film which comprises pulling a malleable film through the bite between at least one pair of cooperating multi-directional orientation rollers having interengaging surface portions thereby imparting a random orientation to the molecular structure of said film during passage between said rollers.
Claim 3
Dependent Claim
22 words
The process as defined in claim 1 wherein said film is laminated to another malleable film which has also been multi-directionally oriented.
Claim 4
Dependent Claim
