Abstract
There is provided an apparatus for dividing logs of substrate into rolls and a method of using this apparatus. The apparatus may include a distribution sprocket, a pocket for holding the log, a cutting device, and a device for collecting the rolls. Logs may be transported, divided, and distributed without the need for secondary clamping devices.
Claims39

- and,
- e) discharging the rolls from the pocket.
A method of making a plurality of wet wipes rolls comprising:
- a) placing a wet wipes log on a conveyor, the log having a length, a width and a moisture content of at least about 65%;
- b) advancing the conveyor;
- c) discharging the log from the conveyor into a holding support;
- d) advancing the support containing the log toward a plurality of cutting blades;
- e) engaging the log and the cutting blades, whereby the log is sectioned into a plurality of rolls;
- and, repeating steps a) through e) so that at least 300 rolls are produced per minute.
A continuous method of cutting a plurality of wet wipes logs comprising:
- a) placing a coreless wet wipes log on a conveyor, the log having a length, a width and a moisture content of at least about 50%;

- d) metering the rate at which the log is discharged from the transfer plate to a pocket;
- e) advancing the pocket containing the log toward a plurality of cutting blades;
- f) engaging the log in the pocket with the cutting blades, whereby the log is cut into a number of shorter rolls;
- g) discharging the rolls from the pocket;
- h) repeating steps a) through g) in a continuous manner;
- and,
- periodically interrupting the repetition of steps a) through g) to move the cutting blades to a position away from pocket;
- and,
- honing the cutting blades while in the away position, whereby material from the honing does not contaminate the pocket, the log, or the rolls.
