Curtain perforation size control table

Width of 3.52m, one at each end, each to the circle for nine centimeters, then the total length deducted 18 centimeters, the remaining 3.34 meters, multiplied by one meter six circles, equal to 20 circles. Must be divided by an odd number to get an even number, 3.3419 = 0.1758 of the empty, and then from any end of the nine centimeters to start measuring and drawing 17.58 centimeters, the more accurate the better.

What is the calculation method of curtain perforation?

1, if there is no splicing pattern, all plain cloth curtains, first measure the total length of the curtains, this side is to remove the length of the cloth tape. Measured length multiplied by 6, that is, we need to play the number of circles, if an even number, such as calculated to be 9, then according to the 10 calculation. The distance between the holes, with the measured length of the cloth, minus 7 centimeters on each side, a **** 14 centimeters, the number obtained divided by the number of laps just, which is the length of the hole spacing. The length of the first hole and the last hole from the side of the cloth, it is calculated by dividing the hole distance by 2.

2, if the curtains are on the flower of the fabric, it is from the middle of the cloth above the pattern of flowers, the left and right side of the amount of 8 centimeters each hole, this is simpler than the plain cloth, do not need to measure the distance between the holes.

3, if it is a plain cloth splicing models of curtains, we are divided into three parts, the first hole and the last hole in the side of the cloth 7 cm, the middle of the splicing of the hole in the first section of the cloth behind the 6 cm hole, if the first section of the cloth to play 4 holes, the length of the first section of the cloth and the second section of the cloth measured divided by 3, that is, the distance of the holes in the first section, the distance of the holes in the second section is the length of the second section of the cloth and the third section of the second section, divided by the number of holes to be played. Divided by the number of holes to be punched, remember to take an even number.

The second section is the length of the second and third sections of the cloth.
