Problems solved by technology

[0003] When the umbrella fabric is stitched by several umbrella pieces, the patterns on the seamed edges of the umbrella pieces will be covered up after sewing. If there is no process improvement, the patterns between the umbrella pieces will be misplaced. This is why most umbrella manufacturers cannot The reason why the printing on the umbrella surface consists of several umbrella patterns to form a complete pattern

Embodiment 1

[0072] Such as figure 2 As shown, a 8K regular octagonal umbrella surface has eight equally divided triangular pieces, and its printing method is as follows: Figure 2-Figure 14 As shown, the specific steps are as follows:

[0073] Step 1: The umbrella manufacturer provides the original design of the umbrella pattern, which is a cat pattern;

[0074] Step 2: If Figure 5 As shown, design the original according to the Figure 4 The regular octagon composition of the orthographic projection of the umbrella surface, and draw the splicing lines according to the shape and number of the umbrella surface splices. Specifically, the splicing lines divide the regular octagonal composition into eight identical triangles;

[0075] Step 3: Cut out a square draft of the splice; Figure 7 As shown, the first draft of the tab includes a pattern bounded by the bottom edge of the tab and the tab line (that is, the pattern inside the triangle), and also includes a part of the pattern outsid...

Embodiment 2

[0083] Such as Figure 15 As shown, an 8K umbrella cover has four long and narrow triangular joints and four short and wide triangular joints. The printing method is as follows: Figure 15-Figure 27 As shown, the specific steps are as follows:

[0084] Step 1: The umbrella manufacturer provides the original design of the umbrella pattern, which is a cat pattern;

[0085] Step 2: If Figure 18 As shown, design the original according to the Figure 17 The octagonal composition of the orthographic projection of the umbrella surface, and draw the splicing lines according to the shape and number of the splicing pieces of the umbrella surface. Specifically, the splicing lines divide the octagonal composition into four pieces of long and narrow triangle pieces and four pieces of short pieces. Wide triangular tabs;

[0086] Step 3: Cut out a square draft of the splice; Figure 20-21 As shown, the first draft of the tab includes a pattern bounded by the bottom edge of the tab and ...

Embodiment 3

[0094] Such as Figure 28 As shown, a 24K regular 24-sided umbrella surface has 24 equally divided triangular pieces, and its printing method is as follows: Figure 28-37 As shown, the specific steps are as follows:

[0095] Step 1: The umbrella manufacturer provides the original design of the umbrella pattern, which is a cat pattern;

[0096] Step 2: If Figure 28 As shown, design the original according to the Figure 30 The regular twenty-four-sided composition of the orthographic projection of the umbrella surface, and draw the splicing lines according to the shape and number of the umbrella surface splices. Specifically, the splicing lines divide the octagonal composition into twenty-four equally divided triangles. piece;

[0097] Step 3: Cut out a square draft of the splice; Figure 33 As shown, the first draft of the tab includes a pattern bounded by the bottom edge of the tab and the tab line (that is, the pattern inside the triangle), and also includes a part of t...

Abstract

The invention provides an umbrella cloth printing method capable of eliminating the influence of sewing on pattern integrity and an umbrella. The umbrella cloth printing method comprises the following steps: 1, obtaining an umbrella cover design original; 2, composing a picture and drawing splicing lines; 3, setting cutting positions, and cutting each splicing first draft; 4, drawing a splicing plate according to a splicing original plate; 5, deforming the bottom edge and the height of each splicing first draft according to the splicing plate; 6, deforming the hem of each splicing first draft according to the splicing plate to obtain a splicing draft; 7, repeating the step 5 and the step 6, and deforming all the splicing first drafts to form a splicing draft; 8, typesetting and printing; and 9, sewing a finished product. According to the umbrella cloth printing method, a method of segmenting all splicing pieces in advance is adopted, and the hem size of the splicing pieces is taken into consideration before printing, so that dislocation cannot occur at joints after an umbrella cover is sewn, and the pattern of the umbrella cover is complete.

Description

technical field [0001] The invention relates to the technical field of umbrella cloth printing, in particular to an umbrella cloth printing method and an umbrella tool that eliminates the effect of stitching on pattern integrity. Background technique [0002] Common umbrellas on the market, the umbrella fabric preparation process generally needs to go through large cutting, small cutting, printing, assembling and other processes. Among them, the big cut is to cut a roll of umbrella cloth into a strip shape; the small cut is to cut the long strip shape into a piece of umbrella sheet after the big cut; printing is to print the pattern on the cut umbrella sheet; Combine the pieces, and sew several pieces of umbrella pieces into a complete umbrella surface. [0003] When the umbrella fabric is stitched by several umbrella pieces, the pattern on the seamed side of the umbrella piece will be covered after sewing. If there is no process improvement, the patterns between the umbrel...
