Abstract
Abstract A web handling apparatus for selectively positioning web rolls so that the web from each roll can be moved past a work station such as a splicing station comprising a frame and a suspension arm pivoted to the frame for swinging movement about a horizontal axis. The arm is movable between first and second positions on each side of a vertical plane containing the horizontal axis. A pair of roll supports are positioned on the arm such that when the arm is in the first position, one roll is supported so that the web thereof is aligned longitudinally with a work station, and when the arm is in the second position, the other roll is supported with the web longitudinally aligned with the work station whereby the web can be removed and moved horizontally past the work station.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
202 words
A web handling apparatus for selectively positioning a pair of web rolls so that the web from each roll can be moved past a work station, such as a splicing station, comprising a frame, a suspension arm having a first end pivoted to and depending from said frame for swinging movement about a horizontal axis, said arm being movable between first and second positions on each side of a vertical plane containing the horizontal axis, positioning means for moving the suspension arm between said first and second positions comprising a cylinder including a cylinder housing mounted on said frame and a shaft connected to said suspension arm, a pair of roll supports attaching on a second end of said suspension arm positioned such that when the arm is in said first position, one roll of said pair of web rolls is supported so that the web thereof is aligned longitudinally with a work station, and when the arm is in said second position, the other roll of said pair of web rolls is supported with the web thereof longitudinally aligned with the work station, whereby the web can be removed from a said longitudinally aligned roll and moved past the work station.
Claim 2

202 words
A web handling apparatus for selectively positioning a pair of web rolls so that the web from each roll can be moved past a work station, such as a splicing station, comprising a frame, a suspension arm having a first end pivoted to and depending from said frame for swinging movement about a horizontal axis, said arm being movable between first and second positions on each side of a vertical plane containing the horizontal axis, positioning means for moving the suspension arm between said first and second positions comprising a cylinder including a cylinder housing mounted on said frame and a shaft connected to said suspension arm, a pair of roll supports attaching on a second end of said suspension arm positioned such that when the arm is in said first position, one roll of said pair of web rolls is supported so that the web thereof is aligned longitudinally with a work station, and when the arm is in said second position, the other roll of said pair of web rolls is supported with the web thereof longitudinally aligned with the work station, whereby the web can be removed from a said longitudinally aligned roll and moved past the work station.
Claim 3
Dependent Claim
36 words
The web handling apparatus set forth in claim 1 including shock absorber means associated with the first and second positions of said arm for absorbing and decelerating the movement of the arm to the respective positions.
Claim 4
Dependent Claim
31 words
The web handling apparatus set forth in claim 1 including brake means associated with each said roll support for providing a drag on the web roll supported by the roll support.
Claim 5
Dependent Claim
201 words
A web handling apparatus for selectively positioning a pair of web rolls so that the web from each roll of said pair of rolls can be moved past a work station, such as a splicing station, comprising a frame comprising a horizontal bridge member and legs supporting said bridge member, a suspension arm having a first end pivoted to and depending from said bridge member for swinging movement about a horizontal axis, said arm being movable between first and second positions on each side of a vertical plane containing the horizontal axis, a pair of roll supports attaching on a second end of said arm positioned such that when the arm is in said first position, one roll support of said pair of rolls is supported so that its said roll has its axis extending horizontally and the web thereof is longitudinally aligned with a work station, and when the arm is in said second position, the other roll of said pair of rolls is supported so that its said roll has its axis extending horizontally and the web thereof is longitudinally aligned with the work station, whereby a longitudinally aligned web can be removed and moved past the work station.
Claim 6
Dependent Claim
201 words
A web handling apparatus for selectively positioning a pair of web rolls so that the web from each roll of said pair of rolls can be moved past a work station, such as a splicing station, comprising a frame comprising a horizontal bridge member and legs supporting said bridge member, a suspension arm having a first end pivoted to and depending from said bridge member for swinging movement about a horizontal axis, said arm being movable between first and second positions on each side of a vertical plane containing the horizontal axis, a pair of roll supports attaching on a second end of said arm positioned such that when the arm is in said first position, one roll support of said pair of rolls is supported so that its said roll has its axis extending horizontally and the web thereof is longitudinally aligned with a work station, and when the arm is in said second position, the other roll of said pair of rolls is supported so that its said roll has its axis extending horizontally and the web thereof is longitudinally aligned with the work station, whereby a longitudinally aligned web can be removed and moved past the work station.
Claim 7
Dependent Claim
214 words
A web handling apparatus for selectively positioning a pair of web rolls so that the web from each roll of the pair of said rolls can be moved past a work station, such as a splicing station, comprising a frame comprising a horizontal bridge member and legs supporting said bridge member, a suspension arm having a first end pivoted to and depending from said bridge member for swinging movement about a horizontal axis, said arm being movable between first and second positions on each side of a vertical plane containing the horizontal axis, positioning means for moving the suspension arm between said first and second positions, a pair of roll supports attaching on a second end of said arm positioned such that when the arm is in said first position, one roll support is supported so that its roll of said pair of rolls has its axis extending horizontally and the web thereof is longitudinally aligned with a work station, and when the arm is in said second position, the other roll support is supported so that its roll of said pair of rolls has its axis extending horizontally and a longitudinally aligned web thereof is longitudinally aligned with the work station, whereby the web can be removed and moved past the work station.
Claim 8
Dependent Claim
214 words
