Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
153 words
Apparatus for conveying a web, comprising: (a) means for conveying a web along a path; (b) a web guide having a web conveying surface extending between a first end and a second end along a longitudinal axis, said web conveying surface extending between a pair of longitudinally extending laterally side plates; (c) means for supporting said web guide in said web path so that said web passes over said web conveying surface from said first end of said web conveying surface to said second end of said web conveying surface between said pair of side plates, said supporting means enabling said web guide to pivot about an axis adjacent said second end of said web guide and transverse to said longitudinal axis of said web conveying surface and to the web so that transverse movement of the web is attenuated between said first end and said second end of said web conveying surface.
Claim 2
Dependent Claim
153 words
Apparatus for conveying a web, comprising: (a) means for conveying a web along a path; (b) a web guide having a web conveying surface extending between a first end and a second end along a longitudinal axis, said web conveying surface extending between a pair of longitudinally extending laterally side plates; (c) means for supporting said web guide in said web path so that said web passes over said web conveying surface from said first end of said web conveying surface to said second end of said web conveying surface between said pair of side plates, said supporting means enabling said web guide to pivot about an axis adjacent said second end of said web guide and transverse to said longitudinal axis of said web conveying surface and to the web so that transverse movement of the web is attenuated between said first end and said second end of said web conveying surface.
Claim 3
Dependent Claim
12 words
The apparatus of claim 1, wherein said web conveying surface is arcuate.
Claim 4
Dependent Claim
46 words
The apparatus of claim 1, wherein said web guide further includes means for restricting movement of the web away from said web conveying surface as the web passes from said first end of said web conveying surface to said second end of said web conveying surface.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1, wherein said web conveying surface is adapted to minimize friction with the web as the web passes over said web conveying surface.
Claim 6
Dependent Claim
183 words
Apparatus for conveying a web from a roll of the web, comprising: (a) means for rotatively supporting the roll of the web; (b) means for continuously pulling the web from the roll along a web path to a desired location relative to said frame; (c) a web guide having a web conveying surface extending between a first end and a second end along a longitudinal axis, said web conveying surface extending between a pair of longitudinally extending laterally spaced side plates; and (d) means for supporting said web guide in said web path so that the web passes over said web conveying surface from said first end of said web conveying surface to said second end of said web conveying surface between said pair of side plates, said mounting means enabling said web guide to pivot about an axis adjacent said second end of said web guide and transverse to said longitudinal axis of said web conveying surface and the web so that transverse movement of the web is attenuated between said first end and said second end of said web conveying surface.
Claim 7
Dependent Claim
183 words
