Abstract

A method of transferring items, such as rolled absorbent product. The method includes the steps of feeding one or more input streams of items toward a turret having a longitudinal axis and arms for engaging the items, the arms being rotatable about the longitudinal axis. The arms can engage at least one of the items from at least one of the one or more input streams and rotate away from the input streams and into a position aligned with one or more output streams. The number of input streams can be different than the number of output streams. The items can be fed onto the one or more output streams.

First claim

What is claimed is:

1. A method of transferring sanitary tissue products
comprising:
feeding one or more separate input streams of sanitary tissue products toward a turret having a longitudinal axis and arms for engaging the sanitary tissue products, the arms being rotatable about the longitudinal axis;
engaging at least one of the sanitary tissue products from the input stream(s) with the arms;
rotating the arms away from the input stream(s) and into a position aligned with one or more separate output streams of sanitary tissue products wherein the total number of input streams of sanitary tissue products is different than the total number of output streams of sanitary tissue products; and
feeding the sanitary tissue products onto the output stream(s).

2. The method of claim 1 , comprising accelerating the rotatable arms between at least one of the input streams and at least one of the output streams.

3. The method of claim 1 , wherein more than one of the sanitary tissue products are engaged from the input stream(s).

4. The method of claim 3 , wherein the arms are radially expandable rods, and wherein the engaging step comprises radially expanding at least one of the rods, and the sanitary tissue products are engaged from an interior void by inserting the rods into the void and expanding.

5. The method of claim 4 , wherein each of the sanitary tissue products have a core defined therein, and wherein the engaging step comprises positioning at least some of the rods at least partially through the cores.

6. The method of claim 1 , wherein the arms are fixed to the turret and the turret rotates about the longitudinal axis.

7. The method of claim 1 , wherein the feeding of sanitary tissue products onto the output stream is via a pusher mechanism.

8. The method of claim 1 , wherein the arms have comprise a carrier mechanism, the carrier mechanism comprising a base and a plurality of rods.
