Abstract
Abstract A device for controlling the position of the edge of a moving web in a web feeding apparatus in which a contact feeding station succeeds a noncontact feeding station. This device comprises a contact roller downstream of an air cushion web-feed station, said contact roller being pivoted about an axis not parallel to the surface of the outgoing web.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
209 words
In a web feeding apparatus including a web floating, noncontact feed station and a roller contact feeding station, a web position controlling device comprising: 1. a first controlling roller serving as substantially the first roller to be in contact with the web at the contact feeding station, said first controlling roller being: a. mounted for rotation about a first axis concentric to the rolling surface of said controlling roller and b. mounted for pivoting about a second axis perpendicular to said first axis and also perpendicular to an imaginary line located in a right section of said controlling roller and connecting the center of said controlling roller to a point on the rolling surface thereof halfway between the point where the web first comes in contact with said controlling roller and the point where the web ceases to be in contact with said controlling roller when the web is in a standard position; 2. a web position detecting means disposed in the vicinity of said first controlling roller on the web approach side; and 3. means for pivoting said first controlling roller about said second axis when said web position detecting meAns detects that the web has deviated from a standard position relative to said web position detecting means.
Claim 2
Dependent Claim
209 words
In a web feeding apparatus including a web floating, noncontact feed station and a roller contact feeding station, a web position controlling device comprising: 1. a first controlling roller serving as substantially the first roller to be in contact with the web at the contact feeding station, said first controlling roller being: a. mounted for rotation about a first axis concentric to the rolling surface of said controlling roller and b. mounted for pivoting about a second axis perpendicular to said first axis and also perpendicular to an imaginary line located in a right section of said controlling roller and connecting the center of said controlling roller to a point on the rolling surface thereof halfway between the point where the web first comes in contact with said controlling roller and the point where the web ceases to be in contact with said controlling roller when the web is in a standard position; 2. a web position detecting means disposed in the vicinity of said first controlling roller on the web approach side; and 3. means for pivoting said first controlling roller about said second axis when said web position detecting meAns detects that the web has deviated from a standard position relative to said web position detecting means.
Claim 3
Dependent Claim
20 words
a web position detecting means disposed in the vicinity of said first controlling roller on the web approach side; and
Claim 4
Dependent Claim
20 words
a web position detecting means disposed in the vicinity of said first controlling roller on the web approach side; and
Claim 5
Dependent Claim
13 words
mounted for rotation about a third axis parallel to said first axis; and
Claim 6
Dependent Claim
13 words
mounted for rotation about a third axis parallel to said first axis; and
Claim 7
Dependent Claim
23 words
A web position controlling device as claimed in claim 1 wherein said second axis is perpendicular to the surface of the outgoing web.
Claim 8
Dependent Claim
34 words
means for pivoting said first controlling roller about said second axis when said web position detecting meAns detects that the web has deviated from a standard position relative to said web position detecting means.
Claim 9
Dependent Claim
34 words
means for pivoting said first controlling roller about said second axis when said web position detecting meAns detects that the web has deviated from a standard position relative to said web position detecting means.
Claim 10
Dependent Claim
16 words
A web controlling device as claimed in claim 1 and further comprising a second controlling roller:
Claim 11
Dependent Claim
78 words
mounted for pivoting about said second axis, whereby one surface of the web can be brought into contact with the rolling surface of said first controlling roller and the other surface of the web can be brought into contact with the rolling surface of said second controlling roller, thereby providing more frictional contact between the web and the controlling roller means comprising the two controlling rollers than is provided between the web and the first controlling roller only.
Claim 12
Dependent Claim
78 words
mounted for pivoting about said second axis, whereby one surface of the web can be brought into contact with the rolling surface of said first controlling roller and the other surface of the web can be brought into contact with the rolling surface of said second controlling roller, thereby providing more frictional contact between the web and the controlling roller means comprising the two controlling rollers than is provided between the web and the first controlling roller only.
