Abstract

An apparatus and methods for producing at extremely high production speeds small pouches filled with tobacco or other granular, powdered or solid content. An endless web substrate, with or without flavor film thereon, is formed into a tubular shape with a longitudinal seam. The tube is cut to individual lengths, and a procession of tubes is crimp-closed at one end, filled and crimp-closed at the other end to complete pouch production. During production, the seams formed at the crimped ends of the pouch are parallel to one another and the longitudinal seam of the pouch is midway between the sides of the pouch and orthogonal to the seams formed at the crimped ends of the pouch.

First claim

What is claimed is:

1. A poucher for producing filled pouches, the pouches having a predetermined pouch length, comprising:
a source of web;
a garniture configured to form the web into a hollow endless tube, with overlapping edge portions of the web establishing a longitudinal seam;
a cutter configured to initially cut the hollow endless tube into multi-pouch length tubular elements having opposite ends;
a transfer section configured to transfer the multi-pouch length tubular elements onto a receiving portion of a series of transfer drums, the series of transfer drums configured to establish and move a procession of the multi-pouch length tubular elements along a path, the series of transfer drums including a cutting drum configured to cut the multi-pouch length tubular elements into individual pouch-length tubes and a beveled transfer drum configured to turn a procession of individual pouch-length tubes from a horizontal disposition to a vertical disposition;
a first closure mechanism at a first location along the path, the first closure mechanism configured to crimp-close one end of each individual pouch-length tube to establish a procession of open-ended pouch structures;
a filling section at a second location along the path, the filling section configured to deposit a predetermined amount of material in each of the open-ended pouch structures to establish a procession of open-ended, filled pouch structures; and
a second closure mechanism at a third location along the path, the second closure mechanism configured to crimp-close the other end of each of the open-ended, filled pouch structures to establish a procession of completed pouches,
wherein the transfer section and the series of transfer drums maintain a consistent location of the longitudinal seam between opposite sides of the completed pouches.

2. The poucher of claim 1 , wherein the transfer section repetitively transfers the multi-pouch length tubular elements from a location adjacent the cutter onto flutes of a first drum of the series of transfer drums.

3. The poucher of claim 1 , wherein the garniture cooperates with a vacuum, the vacuum configured to provide support to an outside portion of the web adjacent the garniture.

4. The poucher of claim 1 , wherein the transfer section moves the multi-pouch length tubular elements longitudinally onto flutes of a catcher drum.

5. The poucher of claim 4 , wherein the transfer section further comprises vacuum-assisted rotating rollers configured to help move the multi-pouch length tubular elements onto the flutes of the catcher drum.

6. The poucher of claim 4 , wherein the catcher drum rotates relative to a fixed arcuate rail so as to rotate the multi-pouch length tubular elements into a predetermined desired radial orientation.

7. The poucher of claim 1 , further comprising:
a sensor located along the path after the second location of the filling section, the sensor configured to generate a signal indicative of a level of content; and
a controller, the controller programmed to adjust operation of the filling section responsively to the signals of the sensor.

8. The poucher of claim 7 , further comprising:
a rejection station located along the path after the second location of the filling section, configured to remove completed pouches from the procession, the controller programmed to operate the rejection station responsive to a signal from the sensor indicative of an unacceptable filling operation.

9. The poucher of claim 8 , wherein the rejection station is located prior to the third location of the second closure mechanism.

10. The poucher of claim 8 , wherein the rejection station is located after the third location of the second closure mechanism.

11. The poucher of claim 8 , further comprising:
a second sensor in cooperation with the controller, wherein the rejection station is configured to inspect and reject completed pouches according to additional criteria.

12. The poucher of claim 1 , wherein the garniture cooperates with a source of vacuum so as to sustain a tubular web form in the web at the garniture.

13. A method for high speed production of filled pouches containing granular, powder or solid content comprising:
applying a flavor film onto an endless paper substrate;
forming an endless hollow paper tube from the endless paper substrate with opposite edge portions of the paper sealed together forming a longitudinal seam after the applying;
cutting the paper tube into individual pouch-length tubes having opposite ends;
crimp-closing one end of each individual pouch length tube;
filling each crimp-closed individual pouch length tube with the granular, powder, or solid content, the granular, powder, or solid content including tobacco;
crimp-closing the other end of the filled individual pouch length tube to complete pouch formation; and
maintaining the orientation of the crimped end and longitudinal seam throughout pouch formation, so that the crimped ends of the complete pouch formation are parallel to one another and the longitudinal seam extends between the crimped ends located midway between opposite sides of the formed pouch.

14. The method of claim 13 , wherein the cutting includes,
initially cutting the hollow endless tube into multi-pouch length tubular elements, and
subsequently cutting the multi-pouch length tubular elements into the individual pouch length tubes.

15. The method of claim 14 , further comprising:
receiving the multi-pouch length tubular elements; and
transferring the multi-pouch length tubular elements in a downstream direction onto a series of fluted drums.

16. The method of claim 15 , wherein the longitudinal seam of the paper tube is radially aligned outwardly or inwardly with respect to the drum to which the tube is transferred.

17. The method of claim 13 , wherein the granular, powder or solid content includes tobacco.

18. The method of claim 13 , wherein the applying includes applying spaced-apart flavor film pieces onto the paper substrate.

19. The method of claim 13 , wherein
the paper substrate is horizontally formed into a hollow endless tube, and
the crimping and the filling occur with the individual pouch lengths in a vertical disposition.

20. The method of claim 13 , wherein at least one of the forming or the sealing of the hollow paper tube is facilitated by at least one of an interior brush, an interior roller, or an exterior vacuum in cooperation with a garniture.

21. A method of high speed pouching comprising:
repetitively making tubular elements having a multi-unit length;
repetitively transferring the multi-unit tubular elements onto receptacles of a first wheel, the transferring including an operation that establishes a predetermined radial orientation of the tubular elements with respect to a rotational axis of the first wheel;
subsequently transforming the transferred, multi-unit tubular elements into a procession of one-up tubular elements, utilizing wheel-to-wheel operations to cut, grade and align pieces of the multi-unit tubular elements while maintaining the radial orientation in the wheel-to-wheel operations; and
transforming the procession of one-up tubular elements into a completed pouched product by moving the procession of one-up tubular elements along a path that includes stations that partially close, fill and complete closure of the one-up tubular elements.

22. The method of claim 21 , wherein the transforming further includes inspecting the filled or completel
