Abstract

A tube seal apparatus including a sealing iron having a tube sealing end, an insulating shroud having a tube clamping end, wherein the sealing iron is at least partially disposed within the insulating shroud. The apparatus further includes an anvil having a cutting detail and a non-stick membrane disposed between the anvil and the tube clamping end of the insulating shroud. The sealing iron and insulating shroud are configured to advance towards a tube to be sealed positioned between the non-stick membrane and the anvil. The tube clamping end is configured to clamp the tube through the non-stick membrane. The sealing iron is configured to advance towards the tube to melt and seal the tube against the cutting detail through the non-stick membrane.

Claims (24)

1. A method of preparing a tube comprising:

positioning the tube between an anvil and sealing iron surrounded by an insulating shroud;

compressing the tube by advancing the insulating shroud towards the anvil;

cutting the tube with a cutting detail of the anvil; and

sealing the tube with the sealing iron.

2. The method of claim 1 , further comprising the step of disposing a non-stick membrane between the insulating shroud and the tube.

3. The method of claim 2 , wherein the cutting and sealing steps are performed through the non-stick membrane.

4. The method of claim 1 , further comprising, after the step of sealing the tube with the sealing iron, the step of retracting the sealing iron away from the tube.

5. The method of claim 4 , wherein the step of retracting the sealing iron further comprises maintaining the compression of the tube between the insulating shroud and anvil.

6. The method of claim 5 , wherein the step of retracting the sealing iron further comprises solidifying a material of the tube over a period of time.

7. The method of claim 6 , further comprising, after the step of retracting the sealing iron, the step of retracting the insulating shroud from the tube, wherein the tube forms two separate pieces.

8. The method of claim 7 , further comprising, after the step of retracting the insulating shroud, removing at least one piece of the tube.

9. The method of claim 1 , wherein the tube is a portion of a bag.

10. The method of claim 9 , further comprising, prior to the step of positioning the tube, filing the bag with a material through the tube.

11. The method of claim 10 , further comprising, after the step of sealing the tube, removing the bag from the tube cut seal apparatus.

12. The method of claim 11 , wherein each of the steps are repeated sequentially to create a plurality of bags.

13. The method of claim 1 , wherein the cutting detail is configured as a raised portion that causes thinning of the tube after the step of sealing the tube with the sealing iron.

14. The method of claim 1 , wherein the cutting detail is configured to allow a material of the tube to flow away from the cutting detail.

15. The method of claim 1 , wherein the step of sealing the tube occurs when the sealing iron is at a temperature between 100° C. and 350° C.

16. The method of claim 1 , wherein the step of sealing the tube occurs when the sealing iron contacts the tube for between 6 and 30 seconds.

17. The method of claim 1 , wherein the step of sealing the tube occurs when the sealing iron contacts the tube with a force between 80 N and 200 N.

18. The method of claim 1 , wherein the insulating shroud and anvil are comprised polyether ether ketone (PEEK).

19. The method of claim 3 , wherein the non-stick membrane is comprised of polyether ether ketone or polyimide film.

20. The method of claim 1 , wherein the step of sealing the tube further comprises melting the tube with the sealing iron.
