Wrapped. The original fabric 2 of the support may be wound around the laminating drum 20 by about a quarter or a half. Further, the belt-shaped process paper 1 is also wound around the molding drum 40 about a quarter of a turn in a state of being overlapped with the raw material 2 of the support.

Further, as shown in FIGS. 2 and 3, a large number of

concave portions

41, 41,... Are formed on the circumferential surface of the molding drum 40 at a constant pitch in the circumferential direction. The concave portion 41 is formed in a concave curved surface shape so as to gradually become deeper in the center direction from the periphery in order to make the hydrocolloid layer into a mountain shape like the emergency bandage shown in FIG. When the shape of the hydrocolloid layer is not a chevron shape but a constant thickness, the recess 41 of the molding drum 40 is formed to a constant depth.

The laminating drum 20 and the forming drum 40 are placed in a horizontal position with a gap corresponding to the thickness of the belt-shaped process paper 1 and the support 2 and the fluid hydrocolloid material 3 sandwiched therebetween. In parallel.

A reservoir 50 for storing the fluid hydrocolloid material 3 is provided between the belt-like process paper 1 facing the bonding drum 20 and the upper side of the molding drum 40 and the raw material 2 of the support. As shown in FIG. 3, the storage unit 50 includes a pair of side plates that come into contact with both side edges of the belt-like process paper 1 and the support sheet 2 facing each other on the upper side of the laminating drum 20 and the molding drum 40. 51 and 51 are provided. The

side plates

51, 51 are formed in a pair of arcuate shapes along the laminating drum 20 and the molding drum 40 on the lower side, and preferably have packings attached thereto.

As shown in FIG. 1, the fluid hydrocolloid material 3 stored in the storage unit 50 is stored in the hot melt applicator 52 and is transferred from the hot melt applicator 52 to the storage unit 50 by the heat retaining hose 53. Supplied. A nozzle 54 is attached to the distal end portion of the heat retaining hose 53 so that the hydrocolloid material 3 can be supplied to and stopped from the storage unit 50. Further, as shown in FIG. 2, a liquid level sensor 55 is disposed in the vicinity of the storage unit 50, and the nozzle 54 is closed when the hydrocolloid material 3 is about to overflow from the storage unit 50.

The fluid hydrocolloid material 3 is stored in the storage unit 50, that is, the hot melt applicator 52 has a viscosity that does not flow down between the belt-shaped process paper 1 and the raw material 2 of the support. The viscosity is adjusted by.

Then, a pressing roller 60 for forcibly molding the molding portion 2 a is pushed into the concave portion 41 of the support drum 2 into the concave portion 41 of the molding drum 40 and is arranged adjacent to the molding drum 40 on the upstream side of the storage portion 50.

When the belt-like process paper 1 is running on the lower side and the original fabric 2 of the support is running on the upper side, the cooling hood 72 is formed in a bowl shape with the lower side opened, and both sides are cooled. It is joined to the plate 71. Since the cooling hood 72 is formed in a bowl shape having an opening on the lower side, even if the molding portion 2a is molded on the original fabric 2 of the support, the molding portion 2a does not become an obstacle, and the original Anti-2 can progress.

The upstream end of the cooling plate 71 is in contact with the lower end of the molding drum 40 through the belt-shaped process paper 1, the fluid hydrocolloid material 3, and the support material 2. By doing so, the belt-shaped process paper 1, the fluid hydrocolloid material 3, and the raw material 2 of the support are removed from the molding drum 40 and simultaneously run on the cooling plate 71.

Then, on the downstream side of the cooling means 70, the strip-shaped process paper 1 is peeled off from the soft hydrocolloid layer fixed to the original fabric 2 of the support, and the original fabric 4 of the folding separator and the original fabric 5 of the separator are separated. A drum 80 to be bonded to a soft hydrocolloid layer fixed to the original fabric 2 of the support is disposed. On the peripheral surface of the drum 80, a large number of recesses (not shown) are formed in the raw material 2 of the support body into which the molding part 2 a raised by the soft hydrocolloid layer enters.

It becomes a state.

The belt-shaped process paper 1 and the support sheet 2 sandwiching the fluid hydrocolloid material 3 travel along the molding drum 40 and continuously travel in the cooling means 70. In the cooling means 70, the hydrocolloid material 3 is cooled via the belt-shaped process paper 1 and the support original 2, thereby becoming a soft hydrocolloid layer and fixed to the support original 2. Naturally, this soft hydrocolloid layer is also fixed in the molding portion 2a of the original fabric 2 of the support.

The strip-shaped process paper 1 sent out from the cooling means 70 is peeled off from the hydrocolloid layer by the peeling means immediately after being wound around the drum 80, and taken up by the winding roller 81. Subsequently, the hydrocolloid layer and the raw material 2 of the support are advanced by the drum 80, and the raw material 4 of the folding separator and the original material 5 of the separator are overlapped with the exposed hydrocolloid layer.

Subsequently, the overlapped support material 2, the folded separator material 4, and the laminated separator material 5 are cut by the molding means 91 into an emergency adhesive bandage of a predetermined shape. The scraps 8 of the support 2, the folding separator 4 and the combined separator 5 are wound around a winding roller 82 in a roll shape.

The emergency adhesive bandage is sandwiched between the lower packaging material 6 and the upper packaging material 7 from the lower side and the upper side, and both the raw materials 6 and 7 are sealed around the emergency bonding bandage by the sealing means 94. Then, the emergency adhesive bandage cut into a predetermined shape by the cutting means 95 and wrapped in the upper and lower packaging materials is discharged.

Note that the present invention can be variously modified without being limited to the above-described embodiment. For example, when the molding part 2 a is molded by pressing the raw fabric 2 of the support body against the fluid hydrocolloid material 3 in the storage unit 50, the pressing roller 60 may not be provided.

Further, the soft hydrocolloid layer is filled only in the molding portion 2a of the support raw material 2 so that the support raw material 2 and the belt-shaped process paper 1 overlap each other without being interposed in the periphery. Also good. Further, the soft hydrocolloid layer may be fixed to the raw material 2 of the support with substantially the same thickness instead of the chevron shape.
