Description

The present invention relates to a sheet wrapping product in which a single decorative sheet is attached to the surface and side surfaces of a plate-like substrate, and a decorative sheet used therefor.

With the background of the depletion of natural plate materials and the accompanying price increase, it is widely used for building materials, etc., for decorative plate materials in which the surface and side surfaces of plate-like substrates are covered with decorative sheets instead of solid materials. Yes. In that case, in order to make the pattern and color pattern of a decorative sheet appear continuously on the surface and side surfaces of the plate-like substrate, it is preferable to cover them with a single decorative sheet.

Such a sheet wrapping product is known in Patent Document 1 below. The base material 2 used for the sheet wrapping product 1 described in Patent Document 1 has a simple rectangular parallelepiped shape whose side surfaces intersect at right angles, and the surface 2 and the four circumferential side surfaces (first side surface 2b, second side). The decorative sheet 3 used so as to cover the side surface 2c has a triangular shape between the adhering pieces (first side adhering piece 3b. Second side adhering piece 3c) attached to the two adjacent side surfaces 2b and 2c of the base material. After being pasted at the notch 4 and pasted from the surface of the base material so as to cover the first side face 2b, both ends of the first side face sticking piece 3b are folded back and the second side face sticking piece 3c together with the second side face. The sheet wrapping product 1 is formed by sticking to 2c.

Curved chamfer only at one end (left end) 12 surface and four sides sides (or inclined surfaces of the chamfer 13) is subjected substrates is obtained by attaching to cover a piece of the decorative sheet 11. On the side surfaces of these sheet wrapping products 10, the seam 14 of the decorative sheet 11 appears along the corners of the lateral side surface and the rear side surface of the base material. The decorative sheet 11 is given an arbitrary printed pattern such as a wood grain.

The sheet wrapping product 10 shown in FIGS. 1 (a) to 1 (d) uses a decorative sheet 11 cut as shown in FIGS. 2 (a) to 2 (d). That is, the decorative sheet 11 used in the sheet wrapping product 10 of FIG. 1A includes a surface covering portion 11a, a front multiple surface covering portion 11b that covers left and right lateral surfaces from the front surface of the base material, and a rear surface of the base material. And a rear side surface covering portion 11c for covering. The surface covering portion 11a has substantially the same shape and the same dimensions as the substrate surface. The front multi-surface covering portion 11b protrudes forward from the surface covering portion 11a with a width of substantially the same dimension as the base material side surface height (base material thickness), and the length (base) of the base material side surface from the surface covering portion 11a. It has laterally extending portions 11d, 11d that are substantially the same size as the material width) and project to the left and right sides. In addition, the rear side surface covering portion 11c protrudes rearward from the surface covering portion 11a with a width that is substantially the same as the base material side surface height (base material thickness), but there are no protruding portions on the left and right sides. The surface covering portion 11a of the decorative sheet 11 is adhered to the substrate surface, and the front multi-surface covering portion 11b and the rear side surface covering portion 11c are bent along the corners of the front side surface and the rear side surface of the substrate, respectively. The sheet wrapping product 10 of FIG. 1A is obtained by sticking to these surfaces with an adhesive.

The decorative sheet 11 (FIGS. 2B to 2D) used in the sheet wrapping product 10 of FIGS. 1B to 1D is substantially the same, but used for the substrate on which the chamfered portions 12 and 13 are formed. In the case, the length along the surface of the chamfered portions 12 and 13 is taken into consideration for the left and right protruding length of the front multi-surface covering portion 11b, and this is pasted to the lateral side surface through the chamfered portions 12 and 13 of the base material. Sometimes, the front end reaches the corner between the substrate lateral surface and the rear side surface, and the seam between the rear side surface covering portion 11c appears along the corner.

The manufacturing process of the sheet wrapping product 10 of FIGS. 1 (a) to 1 (d) will be described with reference to FIGS. 3 (a) to 3 (d). A plurality of plate-like substrates are sequentially conveyed at predetermined intervals. While transporting at a predetermined speed by the apparatus, the surface covering portion 11a of the long continuous decorative sheet sent out from the roller at a speed synchronized with the transport speed of the base material is adhered to the surface of the base material and disposed on both sides in the transport direction. The roller attaches the central portion of the front multi-surface covering portion 11b to the front surface of the base material, and attaches the rear side surface covering portion 11c to the back surface of the base material. Next, the decorative sheet is cut at a predetermined position between the plate-like substrates (indicated by an arrow 15 in FIGS. 3A to 3D), and unnecessary portions (in FIG. 3A to 3D are hatched portions). Is cut with a laser to obtain a decorative sheet 11 having the shape shown in FIGS. Thereafter, the base material having the decorative sheet 11 attached to the front surface, the front side surface, and the rear side surface is lowered from the conveying device, and the laterally extending portions 11d and 11d of the front multiple surface covering portion 11b of the decorative sheet 11 are left and right of the substrate. The sheet wrapping product 10 shown in FIGS. 1A to 1D is manufactured by manually sticking to the side surface. Instead of manual work, the base material with the decorative sheet 11 attached to the front surface, front side surface and rear side surface is transferred to another transport device, and the decorative sheet for the left and right side surfaces of the substrate is provided with rollers arranged on both sides of the transport direction. A pasting operation may be performed. When it is necessary to attach a decorative sheet to the back surface of a tread board for an open staircase, a step of attaching another decorative sheet to the back surface of the substrate is added before or after the above step.

In the above description, the sheet wrapping product 10 in which the front surface and the four side surfaces (or the back surface) of the plate-like base material are coated with the decorative sheet 11 has been described, but the present invention is not limited to this. A sheet wrapping product in which the surface of the plate-like substrate, the front side surface, and the left and right side surfaces are covered with the decorative sheet 11 from which the rear side surface covering portion 11c is omitted may be used. If the back side covering portion 11c of the decorative sheet 11 is omitted, the base sheet is exposed without the decorative sheet being attached to the rear side surface of the plate-like base material, but the base side rear surface is abutted against a wall surface or the like. Such an embodiment is also within the scope of the present invention because it is not necessary to apply makeup to the rear side surface of the base material in a sheet wrapping product (such as a stair stepping board or a counter) that is applied in a wet state. According to this embodiment, since the area of the decorative sheet 11 can be reduced by the omission of the rear side surface covering portion 11c, the cost associated with the decorative sheet can be reduced while maintaining a good appearance in the construction state.

In addition, in the case where the chamfered portions 12 and 13 are provided on only one of the front corners of the front side surface of the base material (for example, FIG. 1 (d)), not only the rear side surface covering portion 11c is omitted, A sheet in which the surface of the plate-like substrate, the front side surface, and the one side surface are covered with the decorative sheet 11 in which the laterally extending portion 11d of one of the front multiple surface covering portions 11b (the chamfered portion non-forming side in this embodiment) is also omitted. It may be a wrapping product. If the rear side surface covering portion 11c and the laterally extending portion 11d of the decorative sheet 11 are omitted, the base material is exposed without attaching the decorative sheet to the rear side surface and the lateral side surface of the plate-shaped base material. In the case of sheet wrapping products (stair treads, counters, etc.) that are constructed with the back side of the base and the lateral side abutted against the wall, etc., there is no need to apply makeup on these sides of the base. Such an embodiment is also within the scope of the present invention. According to this embodiment, in addition to the cost reduction effect due to the small area of the decorative sheet as described above, unnecessary portions when the decorative sheet is cut (shaded portions in FIGS. 6A to 6D) ) Becomes smaller, the cost associated with the decorative sheet can be greatly reduced while maintaining a good appearance in the construction state.
