Definitions
- a thin-walled continuous tube of indefinite lengths is coated internally by shirring said tube on a mandrel having a longitudinal passage while introducing a solution, emulsion, or dispersion of an adherent coating material in a liquid carrier through said mandrel to coat the in terior of the tube.
- the coating is applied as a solution, emulsion, or dispersion of a coating material in a liquid carrier comprising water, an organic solvent, or a mixture such as aqueous glycerol.
- Coating materials which are not soluble may be dispersed in the liquid carrier using any suitable surfactant.
- a coating addon of 30-90 drops is disclosed for an 84 foot shirred strand.
- This invention relates to new and useful improvements in methods and apparatus for coating the inside of small diameter thin-walled flexible tubes.
- Thin-walled small diameter tubes of plastic are made for a variety of purposes.
- Thin-walled small diameter tubes of regenerated cellulose (with or without fibrous reinforcement), cellulose derivatives, amylose, alginates, collagen, etc. are well known for use as flexible molds or casings for the formation of sausages.
- Another object of this invention is to provide a new and improved method for coating the inside of thinwalled flexible tubes of relatively small diameter.
- Another object of this invention is to provide a new and improved apparatus for coating the inside of thinwalled flexible tubes.

- Another feature of this invention is the provision of a new and improved apparatus for coating the inside wall of thin-walled tubes, especially tubes of small diameter, while shirring or pleating a predetermined length of the tube.
- This invention comprises a new and improved method for the internal coating of thin-walled tubes while shirring or pleating a predetermined length of the tube.
- thin-walled tubes such as natural or artificial sausage casings were shirred or pleated into relatively short easily handled lengths by moving the tube over a hollow mandrel, inflating the tube around the mandrel, and shirring or pleating the tube by hand on the mandrel.
- machines were designed, such as that shown in Dietrich US. Patent 2,010,626, which replaced the fingers of a hand shirring operator with mechanically operated dogs or lugs which would engage an inflated tubing and move it to form an accordion pleated or shirred product.
- the coating material may be applied through the hollow mandrel of any of the several shirring machines described in the various patents mentioned above, or through a hollow mandrel onto which a casing is shirred by hand. Generally, the coating material must be introduced with the air or other gas which is blown into the hollow tube to keep it inflated during the shirring process.
- FIG. 1 is a view in side elevation of a shirring machine (with much detail omitted) of the type shown in Blizzard et al. US. Patents 2,722,714, 2,722,715 and 2,723,201, which may be used for internal coating of hollow tubing or casings in accordance with this invention,

- the coating materials may be applied as is, i.e., neat, where liquid coatings are used, or in the form of aqueous or nonaqueous solutions, emulsions, latices, dispersions, and the like.
- Reactive materials may also be applied as internal coatings in this process. Suitable materials include fatty ketene dimers in the form of emulsions or mineral oil solutions or suspensions, isocyanates, ethylene imine, etc. In evaluating the eflj'ectiveness of this internal coating process, a large variety of coating materials were used.
- Example I Solutions or suspensions in a concentration range from 0.2 to 2% were prepared in (1) food grade mineral oil, (2) an edible vegetable oil, and (3) twelve percent glycerol solution in water, using the following materials as the solute or dispersed phase for coating the inside of casing or tubing:
- the coating solutions were introduced through the interior of the shirring mandrel along with the compressed air used to inflate the casings during shirring.
- a shirred casing was obtained hav ing a coherent uniformly dispersed coating over the entire inner surface of this casing.
- the casings which were coated in this manner were with cetyl alcohol, lecithin, fatty ketene dimers, methocel, silicone oil, or stearato chromyl chloride and were found to be more easily peeled from sausages which were stuffed into the casing.
- Example II It has been found that reactive materials such as tolylenediisocyanate, oetadecylisocyanate, and fatty ketenes dimers can be coated on the inside of cellulose tubes (casings) to provide hydrophobic coatings which reduce the rate of water uptake by the cellulose. In the case of cellulose casing, the reduced rate of water uptake provides a substantial increase in strength during the time that the casing is stutfed with sausage emulsion.
- reactive materials such as tolylenediisocyanate, oetadecylisocyanate, and fatty ketenes dimers can be coated on the inside of cellulose tubes (casings) to provide hydrophobic coatings which reduce the rate of water uptake by the cellulose. In the case of cellulose casing, the reduced rate of water uptake provides a substantial increase in strength during the time that the casing is stutfed with sausage emulsion.
- Solutions or dispersions were prepared of (1) 5% octadecyl isocyanate in mineral oil, (2) 5% tolylene diisocyanate emulsified in water with lauryl sodium sulfate, and (3) 10% C1545 fatty ketene dimer in mineral oil. These solutions were used to coat the inside of cellulose casings using the apparatus shown in FIG. 5.
- the coated casings were rewet and inflated with compressed air until they burst. It required 18 seconds inflation to burst the coated samples as compared to 10 sec. to burst an uncoated, rewet, control.
- Example III A mandrel as shown in FIG. 4 was used in the apparuins of FIG. 5 for coating cellulose casing with octadecyl isocyanate.
- a solution of 10% octadecyl isocyanate in mineral oil was applied at the rates of (l) 30 drops per 84 ft. strand and (2) 90 drops per 84 ft. strand.
- Control strands were also prepared by applying mineral oil without the isocyanate to casing at the same rates, i.e. 30 drops and 90 drops per 84 ft. strand.
- the strands were rewet by application of water internally and tested in the inflation burst test of a 20 in. length, as follows:
- Control Isocyanate coating 33 383ll333::1:::3:1:31- 1333 iii It was further noted that the application of water to the exterior of the isocyanate coated casings resulted in a substantial reduction in strength.
- Example IV An experiment similar to Example III was carried out in which cellulose casing was coated with 10% C1645 fatty ketene dimer in mineral oil at a rate of 90 drops per 84 ft. strand. The rewet burst strength was 12.0 p.s.i., compared to 10.2 p.s.i. for the control.
- Example V cellulose.
- the coating material is sprayed into the interior of the tubing or casing in advance of or during shirring. It will be obvious to those skilled in the art that the coating material may be applied by any suitable method of application through the hollow shirring mandrel. Thus, the [coated] coating material may be sprayed into the interior of the casing or tubing or may be applied through a wick or suitable wiping member which would apply the coating to the inner wall of the tubing.
- this invention is applicable to coating the interior of a variety of sausage casings, e.g., regenerated cellulose, both plain and fibrous reinforced; amylase or starch casings; alginate film casings; collagen casings; and the tubular thermoplastic film casings.
- Casing may be from 30-200 feet in length, 1-10 mils in thickness, and 0.5-2.0 inches in diameter.
- the coating materials were added at a level of 30-90 drops per 84 foot shirred strand.
- the various coating materials may be dissolved or dispersed in various liquids, including water, oils, such as mineral oil and vegetable oil, organic solvents such as acetone, toluene, perchloroethylene, carbon tetrachloride, ethylene dichloride, aceto nitrile, cyclohexane, diisopropyl ether or dioxane, and mixtures such as solutions of glycerol in water.
- Coating materials which are not soluble may be dispersed in a liquid carrier using any suitable surfactant, e.g., sodium lauryl sulfate.
- a method of coating the interior of a sausage casing of indefinite length which comprises shirring the casing on a mandrel having a longitudinal passage while introducing a coating composition comprising a solution, emulsion, or dispersion of an adherent coating material in a liquid carrier through said passage to coat the interior of the casing.
- said adherent coating material is lactic acid, calcium lactate, trisodium hexarnetaphosphate, aluminum sulfate, potassium aluminum sulfate, lecithin diammonium phosphate, carboxy methyl [cellularose] cellulose, silicone oil, calcium phytate, inositol, glycero-phosphoric acid, G -C fatty ketene dimers, acetylated monoglycerides of animal or vegetable fats, methyl cellulose, cetyl alcohol, or an organic isocyanate and said liquid carrier is a [good] food grade mineral oil or an edible vegetable oil.
- said casing is of regenerated cellulose, fibrous reinforced regenerated cellulose, amylase, starch, alginate, collagen, or thermoplastic film.
- liquid carrier is water, mineral oil, vegetable oil, acetone, toluene, perchloroethylene, carbon tetrachloride, ethylene dichloride. acetonitrile, cyclohexane, diisopropyl ether, dioxane, glycerol, or aqueous glycerol.
