Abstract
The utility model provides a prototype fast calculating ruler for cutting-out clothes. The utility model is used for cutting-out clothes. The prototype fast calculating ruler for cutting-out clothes is composed of one plastic or hardboard straight ruler which is provided with specific scales. According to the ratio points in common use, the calculation is convenient, and the calculation speed and the drawing speed can be raised. The utility model has the advantages of high precision and simple structure. The prototype fast calculating ruler for cutting-out clothes is a good tool for professional and amateur cutting-out workers.
Description
The utility model relates to a kind of tailoring apparatus, especially a kind of prototype cutting speed-calculating ruler.
At present, the method for cutting out of China's apparel industry, adopt calculated line drawing cutting or ratio cutting more, and uses a chi rough cutting by rule of thumb, and more time-consuming, efficient is low; Method is easy to operate to save time though pattern is cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing, and size can not convergent-divergent; Though the prototype cutting method exact science that Japan generally uses, too tired lock is not suitable for the practice and the teaching of China.
The purpose of this utility model provides a kind of simple for structure, and it is convenient to calculate, can improve cutting speed, prototype cutting speed-calculating ruler easy to learn.
The utility model is the drawing principle according to prototype cutting method, the advantage of comprehensive fundamental mode drawing, and my cutting experience for many years designs.It is to be made by the plastics that specific scale is arranged above, plank or hardboard ruler.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the utility model embodiment schematic diagram.
The utility model is made of the plastics that specific scale is arranged above, plank or hardboard ruler, such as figure, be the long ruler of 30cm, according to required ratio data and the Commonly Used Size degree of enclosing of cutting cloth drafting method, determine with 1/4,1/5,1/6+7,1/20+3 four series, degree of enclosing with 50 centimeters as starting point, adopt 10 systems, press the method for ratio fixed point, arrange in the following manner each point:
Starting point color dot point distance
50 60 70 80 90 100 ... (ratio)
1/4×50=12.5 0.25
1/5×50=10 0.2
1/6 * 50=8.3+7(fixed number)=15.3 0.166
1/20 * 50=2.5+3(fixed number)=5.5 0.05
By starting point 50, color dot 100 arrangement modes are seen the chi reckoning, and less than adopts between two starting points for 10 centimeters and calculates by half, or Chi ratio 1:4,1:5,1:6 calculate, like this, and on the existing length scale of ruler, increased the triplex row dedicated points, (1/5 and 1/20 is delegation).During use, point is used to calculate picture chest measurement, waistline, upper-arm circumference, sleeve sheet; 1/5 is used for picture sleeve sheet; 1/6+7 is used for picture muffs, front mid-arnhole, across back; 1/20+3 is used for open-neck collar.
Prototype cutting speed-calculating ruler of the present utility model is calculated convenient, can improve and calculate and drawing speed, and cutting cloth is accurately rapid, and simple for structure, and cost is low, is suitable for and promotes the use of, and is specialty and amateurish cutter author's serviceable tools.
Embodiment:
Drawing and cutting out a back of the body length is 38 centimeters, the forward and backward garment piece prototype figure of the women's dress that chest measurement is 84 centimeters.
1,, chest measurement 84/2+5=47 centimetre long by 38 according to the back of the body drawn a rectangle,
2、 84/6 +4.5(21-2.5)
4、 84/6 +3 (21-4)
5, the front and back rabat can regard that chest measurement adds 1/4 (84+10)/4 (23.5) of allowance as
6, make the open-neck collar position, draw outline line, drawing is finished.
Claims (1)
1, a kind of prototype cutting speed-calculating ruler is made of a plastic wood board or hardboard ruler, it is characterized in that: on existing length scale, increased triplex row with 1/4,1/5, the ratio dedicated points of four series of 1/6+7,1/20+3 (1/5 and 1/20 is delegation).
