Abstract

PURPOSE:To provide a method for simply and accurately manufacturing a honeycomb type blind by alternately folding a sheet material in a shape of belt to form a pleat type material, laying a thin adhesive layer which extends widthwise at a position of approximately a third of the length of fold, applying the pressure and causing the upper and lower portions of the material to adhere each other between the folds. CONSTITUTION:A belt-shaped sheet material 1 having a prescribed width and an infinite length in a lengthwise direction is alternately folded lengthwise at intervals of a space corresponding to a longitudinal length D of a desired honeycomb type blind, in order to form a pleat type material. Between a fold 2 and a next fold 2 a thin adhesive layer 3 extending widthwise is placed at a position on the outside of these folds and of approximately a third of the length of fold from both edges thereof. Thereafter, the pressure is applied in a vertical direction to the so folded pleat type material to cause the upper and lower portions thereof to adhere each other between one fold and another due to the adhesive layer. Then, the material is severed by a desired length in a lengthwise direction. The so severed pleat type material is extended vertically to form a honeycomb type blind having a desired height and width.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method of manufacturing a honeycomb type plywood as disclosed, for example, in Japanese Patent Application Laid-Open No. 64-87551.

(Conventional Technique? #) Traditionally, this type of honeycomb blind is made by applying a long and narrow adhesive layer that extends horizontally at regular intervals to one sheet material, and then layering another sheet material on top of it. Both are adhered at the above adhesive layer, and a similar adhesive layer is applied on the above another sheet material at a position shifted by half the width of the interval between the above adhesive layers, and then another sheet material is formed. The sheet materials are stacked and bonded, and then multiple sheet materials are stacked and bonded through the same process.After stacking and bonding the sheet materials to the desired thickness in step 5, the above adhesive is applied. A cumbersome process such as cutting at the agent layer was required.

In addition, the above-mentioned Japanese Patent Application Laid-Open No. 64-87351 discloses that the first and second pleated sheets are faced to each other, and the folds of the first sheet are bonded to the protruding portion of the other sheet. discloses a method for manufacturing honeycomb blinds.

In any case, conventional techniques require complicated gluing processes, such as aligning the edges of multiple sheets of material, providing a single line for multiple adhesive applications, or arranging multiple adhesive applications. A large number of kirks are required to cut the material. Furthermore, if the adhesive layer applied to the stacked sheet materials is misaligned, the resulting honeycomb blind will be distorted.

(Problems to be Solved by the Invention) The present invention aims to solve the above-mentioned drawbacks of the conventional method for manufacturing honeycomb blinds and to provide a method for manufacturing honeycomb blinds extremely simply and accurately. be.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention has a belt-shaped sheet material having a predetermined width and an infinite length in the 1M direction, and a honeycomb structure in the longitudinal direction. The pleated material is formed by alternating folds at intervals corresponding to the front-to-back dimension of the blind, and approximately h of the fold interval is formed between each fold and the next fold. A thin adhesive layer extending in the width direction is applied at the position, and pressure is applied in the vertical direction with the above pleated material folded to create a bond between the folds at the above adhesive layer. Glue the upper and lower material parts together, cut the length in the vertical direction to the desired size, cut the width to the desired width if necessary, and stretch this pleated material vertically to the desired width and width. To provide a method for manufacturing a honeycomb blind characterized by forming a honeycomb blind that grows in height.

(5! Example) The present invention will be described below with reference to embodiments shown in the drawings.

FIGS. 1(A), 1(B), and C→ show the sequential steps of manufacturing a honeycomb type blind according to the present invention.

As shown in Fig. 1 (a), a strip-shaped sheet material 1 of a predetermined width and growing to an infinite length in the longitudinal direction is placed in the longitudinal direction of the honeycomb blind. alternating folds at correspondingly spaced positions to form a pleated material, between each one fold 2 and the next fold 2;
A thin adhesive layer 3 extending in the width direction is applied on the outside of the fold and at a position approximately h apart from the crease interval from the apex of the fold, and
With the above pleated material folded, apply pressure in the vertical direction as shown in Figure 1 (b) K to adhere the upper and lower material parts to each other between each fold at the above adhesive layer. , cut the length in the vertical direction to the desired size, cut the width to the desired width according to the required IPK, and stretch this pleat-shaped material vertically as shown in Figure 1. Form an I-Nicum type blind having a height and width of .

As shown in Fig. 2, the honeycomb blind formed in this manner is suspended from the lower surface of the headboard 4, and the bottom rail 5 is attached to the lower part of the headboard 4.
Pass the elevating foot 6 in the vertical direction.

The fly cam type blind is completed by raising and lowering the roller using the auxiliary cord 7 and the operating knob 8 and stopping it using the stopper 9.

When manufacturing cam-type blinds, the adhesive layer may be applied on the upper side of the material between the folds, below 11&c, or above and below m above. You can.

(Effects of the Invention) According to the present invention, processing of the fabric is easier than in the conventional fly cam blind, which is formed by stacking and bonding a large number of sheet materials and cutting them at predetermined intervals. In other words, a roll of fabric was pulled out, pleated to a predetermined width, and adhesive was applied to the outside of the folds and approximately % between the folds, and the pleats were pasted together. A honeycomb blind having two rows of vertically arranged cylindrical parts can be formed by simply using the above method. In this method, the fabric processing equipment is very simple, and since pleating and gluing are performed continuously on a sheet of fabric, there is a process of aligning the edges of a large number of sheet materials and a large number of adhesive applications. There is no need for a cutting device with a large number of curls on the head, and it also prevents the upper and lower fabrics from shifting due to slimy adhesive when pasting the fabrics together. With this method, the fabric is continuous in the vertical direction, so if the pleating process is accurate, the bonding position will not shift.
