Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to a method for producing a poultice, which allows the poultice to be evenly distributed in each part and to form a homogeneous layer when the poultice is applied to a base cloth. This is related.

Background of the Invention: Various poultice treatments are used for sprains, neuralgia, and wounds caused by intradermal inflammation. This poultice is made by mixing anti-inflammatory agents and buffering agents such as methyl salicylate and menthol with non-drying ingredients and applying it to a piece of fabric such as a flannelette and applying it to the affected area. This requires a separate preparation of fabric on which the paste is applied and spread. As a remedy for this problem, plasters are also used, in which a gummy adhesive is applied to the affected skin in advance, along with the necessary medicines as mentioned above, but since the amount of medicine is small, these plasters can be applied to the affected skin. The drug's efficacy is easily exhausted, and even if the amount of medicine is increased, sweat cannot escape due to insufficient breathability, and the layer of sweat insulates the drug from the skin, resulting in a loss of its medicinal efficacy. Therefore, we developed a poultice that has the effects of existing poultices and the comfort of plaster, which is made by mixing and kneading anti-inflammatory agents, buffering agents, astringents, etc. with non-drying moisture on the top surface of a base cloth such as non-woven fabric or flannel. After applying the agent in advance, cover it with a film such as cellophane and distribute or store it. If necessary, peel off the film to expose the bag agent and stick it on the affected area, and then administer the bag at the same time. Bags that can be used are widely used.

Prior art: Pap is manufactured using a two-step process: applying a poultice to a base cloth and attaching a cover film to the surface of the bag. Usually, the process is as shown in Figure 2. Then, a poultice feeder (
2), and pass the entire base sheet (5) between the applicator roll (1) and the poultice feeder (2), and adjust the coating thickness with the doctor (3) attached to the poultice feeder. A poultice (7) K is applied to the upper surface of the base sheet (5), and then the cover film (6) is completely wound and supplied to the film roll (4) (4γ), and the poultice (

is obtained.

However, when using this conventional means, poultices (7),
d It settles onto the base cloth (5) from the poultice feeder (2), the excess is scraped off according to the set position of the doctor (3), and an amount equivalent to the required original is applied onto the base cloth (5). Since the poultice (5) is not press-fitted into the tissue of the base cloth (5) and no additional pressure is applied to the poultice (5) to be applied, there is no air in the viscous poultice (5). Entrainment (more air bubbles are mixed in), and even with the spreading pressure when applying the cover film (6) at 4γ, the air bubbles are not removed, and the supply of the poultice (7) is affected. The lack of a function to level out fluctuations caused variations in the coating thickness, as well as problems with the quality of the pap.

Purpose of the invention: "R"'Aua"69"1"・<-x*+!ili
, , □ This was done with the aim of proposing a method of manufacturing a pap that does not contain air bubbles in the bag agent, has a constant coating thickness, and maintains quality that makes it easy to apply to the affected area. Place the films facing each other under the poultice feeder, and while applying the clamping pressure from the base cloth and cover film to the poultice,
The object of the present invention is to provide a method for obtaining a uniform bag in one movement by applying a poultice to a base cloth and also attaching a cover film.

Structure/Specific Example of the Invention: Hereinafter, a specific example of the method of the present invention will be described based on the drawings.

The method of the present invention involves applying the poultice to the base cloth, adhering the cover film, and applying pressure t in close relation to each other in one step. Specifically, as shown in FIG. A base cloth roll (b) is formed using a friction roll with a rough surface, such as corundum pasted 9, and a film roll (2) parallel to this roll is provided at an appropriate interval. Below the line of approach of the roll (b) and film roll (6), a rolling pressure roll Oaf is provided at an appropriate distance from the film roll @, and above the line of approach, ), the pap can be obtained in one step.

That is, the base cloth (5) is wound non-slip around the base cloth roll (b) rotating clockwise and fed in the direction of the arrow shown in the appendix, and at the same time it is wound around the film roll (to) rotating counterclockwise. Feed the cover film in the direction of the arrow attached. A poultice feeder (2) opens in the area where the base cloth roll (B) and the film roll (2) approach each other (the mechanism for pushing out and pouring the bag agent (7) stored inside is not shown). Pour the bag agent (7) onto both rolls. Here, the base cloth roll αη is like the arrow (&), the film roll (to) is like the arrow (b), and the rolling pressure roll (to) is like the arrow (e).
), and the base cloth roll (
The distance between the film roll (2) and the film roll (2) around the body is slightly larger than the thickness of the bag to be obtained, and the same distance between the film roll (6) and the rolling pressure roll Sakaki is the same as the thickness of the bag to be obtained. It is preferable to set it almost the same as . Also,
The base cloth roll (B), film roll (6), and rolling pressure roll (to) are each individually driven by a motor, for example, for multiple rotations, and the number of rolls for each roll is increased or decreased at the required rotation speed. Rotate freely.

The bag agent (7) poured into the opposing positions of the base cloth (5) and cover film (6) in this way is transferred to the base cloth roll 0D and the film through the base cloth (5) and the cover film (6). Full clamping pressure is applied while being kneaded by the roll (2), and the air bubbles contained inside are completely eliminated and the poultice is applied to the base cloth (5) in a dense state, and a cover film ( 6) adheres to form a bubble, and while passing between the film roll (2) and the spreading pressure roll (to), the bag agent (7) is spread and distributed more evenly, and the necessary Finishing roll according to α fathom σ41'
Apply an emboss finish on the cover film (6), etc., and then proceed to the next step. 7 Ah.

In this case, base cloth roll (b), film roll (2)
) and the rolling pressure roll Sakaki are individually driven so that the feeding or unwinding of the base cloth (5), cover film (6), and pap αQ can be adjusted independently. Setting the pap formation speed corresponding to the difference in can type and viscosity of the bag agent, and eliminating the occurrence of curls or wrinkles in the cover film of the bag.
Contribute to prevention.

Furthermore, if fingers made of thin plates are arranged in parallel in the length direction of the film roll at the lower opening of the poultice feeder (2), the area where these fingers exist The coating of the bag agent disappears or becomes very slight, and a multi-line no-pap line can appear in the length direction of the pap αQ. Furthermore, if the finishing roll a→ on the cover film (6) side is provided with lips perpendicular to the direction of migration of the pap at a predetermined pitch, non-pap lines perpendicular to the length direction of the pap can be produced. The commercially available form of pap is 14Q Min X IQQ

If the length is 100 m, cutting can be performed in the length direction of the pap and each non-pap line perpendicular thereto, which is efficient.

Effects of the invention: When using the method of the present invention, is it possible to add a bag agent to the base fabric? As the cover film is immediately attached to the poultice as soon as it is applied, the poultice hardly ever comes into contact with the air, making it sanitary and preventing deterioration, and ensuring consistent quality as no air bubbles are entrained in the poultice. Bags suitable for medical treatment can be manufactured smoothly and have high industrial applicability.
