Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS

1. A sheet dispensing system for dispensing individual sheets, said sheet dispensing system comprising a frame assembly, a reel loading station, a sheet dispenser station, and a delivery station,

- said reel loading station, said sheet dispenser station, and said delivery station being supported individually or collectively by said frame assembly,

- said reel loading station including a supply reel of a cellulose fiber based web and a support for supporting said supply reel and allowing the dispensing of said cellulose fiber based web from said supply reel,

- said sheet dispenser station including a feeding mechanism and a cutting mechanism,

- said feeding mechanism serving to receive said cellulose fiber based web from said reel loading station and having a tension roller and a feeding roller,

- said cutting mechanism having a reciprocating cutter assembly for cutting said cellulose fiber based web into individual sheets when moved transversally relative to said cellulose fiber based web from a first position to a second position at opposite sides of said cellulose fiber based web,

- said delivery station including a delivery table connected to said sheet dispenser station for receiving said individual dispensed sheets, and

- said reel loading station or said sheet dispenser station or delivery station further comprising a smoothing mechanism having a first guide roller and second guide roller, said first and second guide rollers being adjustable in relation to one another for altering the smoothing angle dependent of the diameter of said supply reel in order to compensate for the curvature of said cellulose fiber based web and provide non-curved individual sheets.

2. The sheet dispensing system according to claim 1 , said cutting mechanism being prevented from cutting when moved in the opposite direction from said second position to said first position,

3. The sheet dispensing system according to claim 1 , said cutting mechanism cutting when moved in the opposite direction from said second position to said first position.

4. The sheet dispensing system according to claim 2 or 3, said first and second guide rollers being adjustable in relation to one another for altering the smoothing angle by a mechanical suspension of the first guide roller and/ or second guide.

5. The sheet dispensing system according to claim 2 or 3, said first and second guide rollers being adjustable in relation to one another for altering the smoothing angle by a mechanical coupling between the first guide roller and the second guide roller.

6. The sheet dispensing system according to claim 2 or 3, said first and second guide rollers being adjustable in relation to one another for altering the smoothing angle by the provision of an electronic controller controlling said first and second rollers in relation to one another in response to an electrical signal generated by a sensor mounted on the loading station or the delivery station.

7. The sheet dispensing system according to claim 6, said controller having an input channel and an out signal, said controller being capable of receiving a signal from a reel sensor connected to said reel loading station for generating said electrical signal being representative of the diameter of said supply reel.

8. The sheet dispensing system according to any of the preceding claims, said cellulose fiber based web being movable continuously, and said cutting mechanism being movable reciprocating in parallel with and in synchronism with said cellulose fiber based web during the cutting of said cellulose fiber based web into said individual sheets.

9. The sheet dispensing system according to any of the preceding claims, said cellulose fiber based web being movable intermittently and said cutting mechanism being movable transversally relative to said cellulose fiber based web during the cutting of said cellulose fiber based web into said individual sheets.

10. The sheet dispensing system according to any of the preceding claims, said cutter assembly of the cutting mechanism being constituted by a blade, a mechanical roller knife or a laser cutter.

1 1 . The sheet dispensing system according to any of the preceding claims, said smoothing mechanism comprising a first second guide roller being mounted on a guide plate, which is pivotally connected to a mounting plate connected with the side wall of the sheet dispenser station housing.

12. The sheet dispensing system according to claim 1 said mounting plate having an arc portion with slots extending the width of said mounting plate, said slots being

arranged near the circumference of the arc shape of said mounting plate, a lever with biasing means is arranged perpendicular on said guide plate, said lever is provided with a pin being substantially longer than the width of said guide plate, and this will allow said lever to provide an interlocking of said guide plate relative to the mounting plate.

13 A method of dispensing individual sheet by means of a sheet dispensing system comprising a frame assembly, a reel loading station, a sheet dispenser station, and a delivery station, said method comprising the following steps:

- providing said frame assembly for individually or collectively supporting said reel loading station, said sheet dispenser station and said delivery station,

- providing said reel loading station including a supply reel of a cellulose fiber based web and a support for supporting said supply reel,

- providing said sheet dispenser station including a feeding mechanism and a cutting mechanism,

- providing said feeding mechanism having a tension roller and a feeding roller,

- providing said cutting mechanism having a reciprocating cutter assembly,

- providing said delivery station connected to said sheet dispenser station,

- providing a smoothing mechanism having a first guide roller and a second guide roller at said reel loading station or said sheet dispenser station or said delivery station,

- dispensing said cellulose fiber based web to said feeding mechanism serving to receive said cellulose fiber based web from said reel loading station

- cutting said cellulose fiber based web by moving said reciprocating cutter transversally relative to said cellulose fiber based web from a first position to a second position at opposite sides of said cellulose fiber based web and preventing cutting when moving said reciprocating cutter in the opposite direction from said second position to said first position,

- adjusting said first or second guide rollers being adjustable in relation to one another, said guide rollers being adjustable for altering the smoothing angle dependent of the diameter of the supply reel in order to compensate for the curvature of said cellulose fiber based web and provide non-curved individual sheets.

- dispensing said individual sheets on said delivery table of said delivery station

14. A method according to claim 13 further including any of the features of the system according to any of the claims 2-12.
