Abstract

PROBLEM TO BE SOLVED: To form gathers on a sheet-like material such as a cloth without sewing or inserting a string or rubber string into a narrow cylindrical member. SOLUTION: This method for forming gathers on a sheet-like material comprises restraining a sheet-like elastic material 3 having rubbery elasticity in an expanded state, adhering or sticking the elastic material 3 to a sheet-like material 6 at plural spaced positions and subsequently releasing the restraint of the elastic material 3. Since the elastic material 3 is thus shrunk, gathers are formed on the sheet-like material 6. The method for forming gathers on the sheet-like material also comprises adhering the sheet-like elastic material having the rubbery elasticity to a shrinkage-preventing material 1 through an adhesive 2 in an expanded state, applying an adhesive 4 at spaces, laminating the sheet-like material 3 to the sheet-like material 6 to form the gathers thereon through an adhesive 4, and subsequently releasing the restraint of the shrinkage- preventing material 1 to form the gathers on the sheet-like material 6.

FIG. 1 shows a state before use of an adhesive body for forming a gather in this embodiment, and shows no or little rubber-like elasticity of paper, plastic, etc. A sheet-shaped and band-shaped elastic material 3 is adhered to one surface (a lower surface in FIGS. 1, 3, 4, and 5) of the sheet-shaped and band-shaped shrinkage preventing material 1 made of a material via an adhesive 2. . The elastic member 3 is made of a cloth or a non-woven fabric or the like containing polyurethane elastic fibers, has rubber-like elasticity, and expands and contracts in its length direction (horizontal direction in the figure). The elastic material 3 is adhered to the anti-shrink material 1 via the adhesive 2 as described above in a state where the elastic material 3 is extended in the length direction. Is held in its extended state. In this embodiment, the adhesive force between the shrinkage preventing material 1 and the adhesive 2 is larger than the adhesive force between the elastic member 3 and the adhesive 2.
In this embodiment, the pressure-sensitive adhesive 2 is entirely adhered to the other surface of the elastic material 3, but the pressure-sensitive adhesive 2 is partially adhered to the elastic material 3, not entirely. You may.

First, as shown in FIG. 3, the peeling sheet 5 is peeled off from the adhesive 4, and then, as shown in FIG. The elastic material 3 is adhered. Next, when the anti-shrinkage material 1 is peeled off from the elastic material 3 as shown in FIG. 5, the elastic material 3 contracts due to its rubber-like elasticity, while the sheet-like material 6 does not shrink. The shape member 6 is formed with gathers. Therefore, it is possible to form a gather on the sheet material 6 simply by adhering the elastic material 3 to the sheet material 6 without sewing or passing a string or rubber string through a narrow cylindrical portion. it can.

The adhesive 19 may be a room temperature curing type (solvent drying type, catalyst addition type, moisture curing type, anaerobic curing type), a thermosetting type, a hot melt type, a heat sensitive type, a pressure sensitive type, It may be a re-wet type or the like.

Next, as shown in FIG. 16, an adhesive 1 is applied to a sheet material 20 such as cloth, paper, plastic or the like on which gathers are to be formed.
The elastic member 18 is overlapped with the elastic member 18 via a bonding material 9, and if necessary, a treatment such as a pressure treatment and a heat treatment is performed. Thereafter, when the anti-shrinkage member 16 is peeled off from the elastic member 18, gathers are formed on the sheet-like member 20 as shown in FIG.

The adhesive 19 may be first applied to the sheet material 20 instead of the elastic material 18. Further, the elastic member 18 may be restrained in an expanded state by means other than the shrinkage preventing member 16 and the adhesive 17.
