Abstract

A cleaner assembly for an apparatus for making pouch products includes a cleaner roller and a poker roller. The cleaner roller may counter rotate with a rotatable drum of the apparatus, in contact with an upper surface of a first elastic layer on the rotatable drum, and at a greater tangential speed than at least one surface of an outer circumferential surface of the rotatable drum or an upper surface of the first elastic layer. The poker roller includes projections that are each configured to extend into one or more divots of the rotatable drum. The poker roller may counter rotate with the rotatable drum and at a same tangential speed as the at least one surface such that the projections extend into and out of separate, respective divots of the rotatable drum based on the counter rotation of the poker roller and the rotatable drum.

First claim

We claim:

1. A method of making a pouch product, the method comprising:
transferring a first material to a first receiving location, the first material including a first elastic layer and a first support layer;
removing a portion of the first support layer from the first elastic layer to form a first web;
conveying the first web to a dosing location;
applying a vacuum to the first web at the dosing location to form first web portions;
filling each of the first web portions with a filler material to form filled first web portions; and
conveying the filled first web portions to a cleaner assembly to
move the filler material on an upper surface of the first material into one or more divots of a plurality of divots, and
compress the filler material in the one or more divots of the plurality of divots,
wherein the conveying of the filled first web portions to the cleaner assembly includes rotating a poker roller relative to the upper surface of the first material, the poker roller including a plurality of projections configured to extend into the one or more divots of the plurality of divots and compress the filler material.

2. The method of claim 1 , further comprising:
conveying the filled first web portions to a second receiving location;
transferring a second material to the second receiving location, the second material including a second elastic layer and a second support layer; and
removing a portion of the second support layer to form a second web.

3. The method of claim 2 , further comprising:
aligning the second web with the first web; and
sealing the second web to the first web to form the pouch product.

4. The method of claim 3 , wherein the sealing includes using a food-grade adhesive.

5. The method of claim 3 , further comprising:
cutting the pouch product from the first web and the second web.

6. The method of claim 5 , wherein the cutting and the sealing includes:
rotating a heat knife assembly roller adjacent to an upper surface of the second web such that a heat knife on the heat knife assembly roller and a divot of the plurality of divots align, and
cutting the first web and the second web with the heat knife.

7. The method of claim 5 , further comprising:
ejecting the pouch product on a conveyor system.

8. The method of claim 1 ,
wherein the transferring of the first material includes transferring the first material across a first dewrinkling roller to reduce wrinkles in the first material, and
wherein the removing of the portion of the first support layer includes:
transferring the first material across a first stripper plate to remove the portion of the first support layer from the first elastic layer, and
rolling the removed portion of the first support layer onto a first scrap roll holder.

9. The method of claim 2 , wherein the transferring of the second material includes transferring the second material across a dewrinkling roller to reduce wrinkles in the second material, and
wherein the removing of the portion of the second support layer includes:
transferring the second material across a stripper plate to remove the portion of the second support layer from the second elastic layer, and
rolling the removed portion of the second support layer onto a scrap roll holder.

10. A method of making a pouch product, the method comprising:
transferring a first material to a first receiving location, the first material including a first elastic layer and a first support layer;
removing a portion of the first support layer from the first elastic layer to form a first web;
conveying the first web to a dosing location;
applying a vacuum to the first web at the dosing location to form first web portions;
filling each of the first web portions with a filler material to form filled first web portions; and
conveying the filled first web portions to a cleaner assembly to
move the filler material on an upper surface of the first material into one or more divots of a plurality of divots, and
compress the filler material in the one or more divots of the plurality of divots,

wherein the conveying of the filled first web portions to the cleaner assembly includes:
compressing a cleaner roller against the upper surface of the first material, and
rotating the cleaner roller relative to the upper surface of the first material to move the filler material on the upper surface of the first material into the one or more divots of the plurality of divots.

11. The method of claim 10 , wherein an outer surface of the cleaner roller rotates at a tangential speed that is at least three times greater than that of the upper surface of the first material.

12. The method of claim 10 , wherein the cleaner roller includes silicone.

13. The method of claim 10 , wherein the cleaner roller is a cylindrical roller or a polygonal cylindrical roller.

14. The method of claim 10 , wherein the first receiving location, the dosing location, and the cleaner assembly are located along a rotation path of an outer surface of a rotatable drum.

15. The method of claim 14 , wherein a smallest spacing distance between the rotatable drum and the cleaner roller is equal to or less than a thickness of the first material.

16. The method of claim 10 , wherein the conveying of the filled first web portions to the cleaner assembly includes:
rotating a poker roller relative to the upper surface of the first material, the poker roller including a plurality of projections configured to extend into the plurality of divots and compress the filler material.

17. The method of claim 16 , wherein:
each divot of the plurality of divots has a first length in a first direction, a first width in a second direction that crosses the first direction, and a first depth in a third direction that crosses the first and second directions,
each projection of the plurality of projections has a second length in a fourth direction that is parallel to a tangent of a curvature of the poker roller, a second width in a fifth direction that crosses the fourth direction, and a second depth in a sixth direction that crosses the fourth and fifth directions,
the second length is smaller than the first length, and
the second width is smaller than the first width.

18. The method of claim 16 , wherein
the plurality of divots include a plurality of separate lanes of divots,
the plurality of projections of the poker roller includes a plurality of lanes of projections extending in parallel around an outer circumferential surface of the poker roller, and
the plurality of lanes of projections are aligned with separate, respective lanes of divots such that respective projections of each separate lane of projections are configured to extend into and out of one or more divots of a separate, respective lane of divots based on the rotation of the poker roller.

19. The method of claim 16 , wherein the cleaner roller is between the poker roller and the dosing location.

20. The method of claim 16 , wherein the poker roller and the cleaner roller are rotated by a same motor.
