(about the winding deviation adjustment part of the roll curtain)

In the above-described roll type curtain, in order to exchange the curtain or to remove the curtain from the winding shaft, and to reattach to the winding shaft after washing, the direction in which the winding is deviated or the amount of deviation may vary. In such a case, it is necessary to re-paste the adjustment patch or add a complicated job such as sticking a patch.

In the thin cloth winding device disclosed in Patent Document 1, since the winding shaft needs to be removed from the support shaft when the annular member is fitted in order to prevent the winding deviation, the adjustment operation of the winding diameter becomes complicated.

In the louver disclosed in Patent Document 2, when the winding is disengaged after the spacer is attached to the winding drum, the spacer needs to be re-attached, so that the adjustment work of the winding deviation becomes complicated.

In the roll type curtain disclosed in Patent Document 3, it is not easy to adjust the amount of twist of the curtain top grip member in order to solve the winding deviation phenomenon. Moreover, there is a possibility that the position where the tape is pasted after the adjustment is deviated. Therefore, the work of releasing the winding deviation becomes complicated.

A first object of the present invention is to provide a winding deviation adjusting member that can easily perform a winding deviation adjustment operation of a curtain, a winding closing device using the adjusting member, and a method of manufacturing or constructing a roll curtain.

(about roll curtains)

As a cloth constituting a curtain of a roll type curtain, some cloths have a characteristic of winding deviation. As shown in Fig. 54, the curtain 52 having the fabric pressing plate 51 attached to and detachable from the winding shaft at the upper end includes a first cloth portion 53 having a thick cloth thickness and a second cloth portion 54 having a thin cloth thickness. In the curtain 52, when the center of the first cloth portion 53 in the width direction does not coincide with the center of the curtain 52 in the width direction, a winding deviation characteristic is generated.

Further, in Fig. 54, the center of the width direction of the first cloth portion 53 is shifted to the left side with respect to the center of the width direction of the curtain 52. Therefore, the thickness of the cloth on the left half of the curtain 52 is on average larger than the thickness of the cloth on the right half. Thereby, a winding deviation to the left side occurs in this curtain 52.

In FIG. 55, the center of the first cloth portion 53 in the width direction is shifted to the right side from the center in the width direction of the curtain 52, so that the winding deviation to the right side occurs.

In Fig. 56, the cloth is attached obliquely with respect to the cloth pressing plate 51, and the lower end of the left end edge of the curtain 52 is deviated to the left side with respect to the vertical line with a deviation from the width t. In such a case, a winding deviation to the left side occurs in the curtain 52.

In Fig. 57, the cloth is attached obliquely with respect to the cloth pressing plate 51, and the lower end of the right end edge of the curtain 52 is deviated to the right side with respect to the vertical line with a deviation from the width t. In such a case, a winding deviation to the right side occurs in the curtain 52.

In Fig. 58, an error occurs between the width of the upper portion of the curtain 52 and the width of the lower portion due to an error in the cutting of the cloth, and the lower end of the left end edge of the curtain 52 is offset to the left side with respect to the vertical line by the deviation width t. In this situation, A winding deviation to the left side occurs in the curtain 52.

In Fig. 59, due to an error in the cutting of the cloth, an error occurs between the width of the upper portion of the curtain 52 and the width of the lower portion, and the lower end of the right end edge of the curtain 52 is offset to the right side with respect to the vertical line by the deviation width t. In such a case, a winding deviation to the right side occurs in the curtain 52.

In Fig. 60, the curtain 52 is cut into a parallelogram shape due to an error in the cutting of the cloth, and the lower end of the left end edge of the curtain 52 is deviated to the left side with respect to the vertical line with a deviation from the width t. In such a case, a winding deviation to the left side occurs in the curtain 52.

In Fig. 61, the curtain 52 is cut into a parallelogram shape due to an error in the cutting of the cloth, and the lower end of the right end edge of the curtain 52 is offset to the right side with respect to the vertical line by a deviation from the width t. In such a case, a winding deviation to the right side occurs in the curtain 52.
