Abstract
Abstract Apparatus for producing a web whose width exceeds the working width of a machine having a number of take-off units and a table for conveying the web, for the production of webs from fibrous material, more particularly cards, carding machines, or pneumatic non-woven formers, the device having deflectors (12) which are associated one each with the take-off units (10) and which, as considered in the operative direction of the machine, are spaced apart from one another by a distance corresponding to the width of the taken-off web, the deflectors (12) extending at an angle to the operative direction of the machine, such angle corresponding to half the angle between the operative direction of the take-off table (10) and that of the table (14) for conveying the textile, and a corresponding method.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
An apparatus for producing a web whose width exceeds a working width of a web portion being produced by a machine, particularly cards, carding machines and pneumatic web formers, said machine having a number of take-off units arranged in a stack and discharging the web portions in a first direction, said apparatus having a conveyor table for conveying the web in a second direction at a first angle from the first direction, each of the take-off units having a deflector extending at one-half of the first angle to both the first and second directions, said deflectors being positioned along the first direction at a spacing from each other equal to a width of the web portion so that the web portions are deflected into the second direction and placed side-by-side with edges contact on the conveyor table.
Claim 2
Independent Claim
137 words
An apparatus for producing a web whose width exceeds a working width of a web portion being produced by a machine, particularly cards, carding machines and pneumatic web formers, said machine having a number of take-off units arranged in a stack and discharging the web portions in a first direction, said apparatus having a conveyor table for conveying the web in a second direction at a first angle from the first direction, each of the take-off units having a deflector extending at one-half of the first angle to both the first and second directions, said deflectors being positioned along the first direction at a spacing from each other equal to a width of the web portion so that the web portions are deflected into the second direction and placed side-by-side with edges contact on the conveyor table.
Claim 3
Dependent Claim
47 words
An apparatus according to claim 1, wherein the first angle between the first direction for the discharge of the take-off units and the second direction for the conveyor table is a right angle and the angle between each deflector and the first and second directions is 45°.
Claim 4
Dependent Claim
15 words
An apparatus according to claim 1, wherein each deflector has a form of a roll.
Claim 5
Independent Claim
132 words
An apparatus for producing a web whose width exceeds the working width of a web portion being discharged from a machine such as a carding machine, said machine having a number of take-off units arranged in the stack and each discharging a web portion in a first direction, said apparatus having a conveyor table for conveying the web portions in the first direction, and at least one of the take-off units having a pair of parallel extending deflectors extending at right angles to the first direction, the deflectors of said pair having a spacing therebetween corresponding to the width of the take-off web portion so that the take-off web portion is offset one width and placed on said conveyor table alongside of an adjacent web portion from a unit free of deflectors.
Claim 6
Independent Claim
132 words
An apparatus for producing a web whose width exceeds the working width of a web portion being discharged from a machine such as a carding machine, said machine having a number of take-off units arranged in the stack and each discharging a web portion in a first direction, said apparatus having a conveyor table for conveying the web portions in the first direction, and at least one of the take-off units having a pair of parallel extending deflectors extending at right angles to the first direction, the deflectors of said pair having a spacing therebetween corresponding to the width of the take-off web portion so that the take-off web portion is offset one width and placed on said conveyor table alongside of an adjacent web portion from a unit free of deflectors.
Claim 7
Dependent Claim
132 words
An apparatus according to claim 4, wherein the machine has three take-off units and includes another pair of deflectors associated with one of the other take-off units, said other pair of deflectors extending parallel at an angle 45° to the first direction and at right angles to the deflectors of the first-mentioned pair with the spacing of the deflectors of the other pair being equal to the width of the web portion of the take-off unit so that the web portion of one take-off unit moves onto the conveyor table without deflection and the web portions on the other two take-off units are disposed adjacent the sides of the first-mentioned web portion to form a web having a width substantially three times the width of the web portion of a single unit.
Claim 8
Dependent Claim
15 words
Apparatus according to claim 4, wherein the deflectors (12) take the form of a roll.
Claim 9
Dependent Claim
31 words
An apparatus according to claim 4, wherein the web is supplied to the deflectors (12) by means of a number of belts or aprons which extend in the direction of movement.
