Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fibrous casing mainly for filling and packaging processed meat products, and more specifically to a strong fibrous casing with threads integrally bonded to its outer peripheral surface, and a method for manufacturing the same. It is related to.

Conventionally, fibrous casings for filling and packaging processed meat products are based on porous paper obtained using wood pulp and cotton linters as the main raw materials, and on this base, fibrous casings made using pulp of the same or nearly the same quality as the base are used. The course is coated and impregnated and regenerated.

Such a fibrous casing can be made uniform in thickness and width, has excellent shrinkage force, has good air permeability, and has a strong smoking effect, making it extremely suitable for filling processed meat products.

However, when filling processed meat into a fibrous casing, a pressure of 3 to 6 kg/crj is usually applied and the fibrous casing is conventionally not strong enough to withstand the pressure and breaks. There is a serious drawback that it may become bagged.

In addition, after filling the fibrous casing with processed meat and subjecting it to smoke boiling, the outer packaging is wrapped in a film made of vinylidene chloride or nylon, but in order to give it a high-class image, a mesh pattern is printed on the outer packaging film. , a separate net can be covered, or the processed meat can be wrapped in cloth or cellophane and then tied with cotton thread.

In the case of printing, the process of overturning the net and tying it with cotton thread is expensive and time-consuming, and requires a considerable degree of skill.

The purpose of the present invention is to eliminate such drawbacks of the prior art,
It has high mechanical strength, so there is no risk of bag breakage when pressurizing the contents, and there is no need for secondary processing, such as separately covering the mesh or winding, making it a good-looking fibrous material. The object of the present invention is to provide a casing and a method for efficiently and continuously manufacturing such a fibrous casing.

Hereinafter, the present invention will be explained in detail based on the drawings.

The material of the fibrous casing body according to the present invention may be the same as the conventional one.

That is, it may be recycled by using a porous paper obtained using wood pulp or cotton linters as the main raw material as a base, and coating and impregnating this base with viscose made from pulp of substantially the same quality as the base.

The fibrous casing according to the present invention is significantly different from the conventional one, as shown in FIG.
Alternatively, the fibrous casing body 1 and the threads 2 are bonded and integrated by arranging them in a mesh shape (see FIG. B).

The thread used is preferably one or several twisted cotton threads or synthetic threads of numbers 20 to 40.

In addition, as for the method of adhesion and integration, as in the method of the present invention described below, it is possible to use viscose, which is normally used when manufacturing fibrous casings, and to integrate it by adhesion during the process of manufacturing fibrous casings. Although it is preferable, a synthetic adhesive may be used to bond threads or a net made of threads to the finished fibrous casing body.

Next, an embodiment of the method for manufacturing a fibrous casing according to the present invention will be described as follows.

As is clear from the explanatory diagram of FIG. 2, first, porous paper 11 obtained using wood pulp cotton linters as the main raw material and cut to a predetermined width is sequentially fed out from a paper supply device (not shown). Ru.

The ends of the perforated papers 11 that are sent one after another are overlapped and pasted together by a joining device 12 to form a cylindrical base 13.

Below the joining device 12, there are two thread feeding devices 14a.
t 14 b is installed, and the yarn feeding device 14 a >
14b feeds out the thread 15 while rotating in opposite directions around the central axis.

Therefore, the two threads 15 are spirally arranged on the outer peripheral surface of the cylindrical base 13 so as to intersect with each other.

Thereafter, the thread 15 and the cylindrical base 13 are coated with viscose made from pulp having the same or similar properties as the porous paper 11 by the viscose coating device 16, and subsequently recycled in the recycling tank 17.

Since the yarn 15 is also coated with viscose and the yarn 15 and the cylindrical base 13 are in contact with each other, the yarn 15 and the cylindrical base 13 are bonded and integrated with each other during playback.

In this way, a thread-filled fibrous casing can be easily obtained.

In the above embodiment, two yarn feeding devices are used, but depending on the case, one device may be used.Also, a yarn knitting device may be provided in place of the yarn feeding device, and the outer peripheral surface of the cylindrical base may be covered with a net. It may be covered.

In that case, the speed at which the net is created and the speed at which the cylindrical base descends must be approximately equal.

In addition, in the above example, viscose is applied after the threads are arranged, but by reversing the order and applying viscose to the cylindrical base, the threads are arranged in a spiral or mesh pattern and recycled. It is a hot topic that the thread and base may be integrated by adhesive.

- Since the present invention is a thread-filled fibrous casing configured as described above and a method for manufacturing the same, there is no difference in the contents even if the processed meat is filled and smoked boiled in the same way as conventional fibrous casings. However, the strength is significantly increased, and therefore, the breakage of the fibrous casing during filling with processed meat and smoke boiling is drastically reduced, and the yield can be improved. There is no need to cover the net,
It is possible to save labor, give the product a sense of luxury, and create a different image than if a mesh pattern was printed on the outer packaging film.

Furthermore, according to the manufacturing method of the present invention, the conventional manufacturing process for fibrous casings can be used as is, and only a yarn feeding device or a yarn knitting device, etc. need to be added, so the manufacturing method is much more complicated than the conventional method. It has a number of excellent effects such as being able to easily and continuously manufacture thread-filled fibrous casings without any problems.
