Method and apparatus for pattern cutting

Abstract

A method for tailoring material constituted by pattern material is provided, wherein multilayer cloth layers (L) are aligned with each other accurately through inserted needle (N) according to the position selected by the pattern, the lamination with needles is positioned on a tailoring backing plate (A) and enters into a tailoring cutter (W) thereof to cut the tailoring layers, before the cloth layers are aligned, the needle (N) is positioned in the tailoring backing plate (A), the lamination (S) is formed directly on the tailoring backing plate (A) and perforated by the needle, the lamination with needles is guaranteed without relative position change relative to the tailoring backing plate (A) by the needle before being positioned through the negative pressure, before fixing tailoring, the needle (N) of the lamination is removed when necessary. In a device used in the method, the tailoring backing plate (A) is a bristle layer (B, B') provided with a needle bed layer (P) for positioning needles inserting into bristle (10) temporarily, the length of each needle is at least equal to the summation of the height of the lamination, the thickness of the needle bed layer and the bristle length on the eedle bed layer.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 8 . Background technique [0002] In a known method used in the garment industry, spaced apart plastic needles are employed in the layup of precisely aligned plies of patterned material. Each plastic needle has a root, a shaft and an upper tip. Before the cloth layers are threaded exactly through each other, the needles pass through the root and are placed on the layer pattern on the placement table at locations selected according to the pattern. The needled stack is then transported to a cutting backing plate in the form of a bristle layer, positioned for example by the effect of vacuum, and cut at the cutting window of the cutting device. It is unavoidable that some layers of cloth warp when being transported to the cutting backing plate, thereby affecting the quality of the cutting. The needle remains in the stack and is broken o...

Problems solved by technology

When the needle or the root of the needle breaks off, resulting in inhomogeneity or damage to the retained material, which is not acceptable for high or very high quality garments

[0003] Thus, in the current garment industry, for high or very high quality garments suitable for patterned materials, an alternative time-critical and labor-intensive method has recently been adopted, wherein method-bound pre-cutting is required, which is of great importance for relatively high-quality garments. Expensive materials will have a significant negative effect on the price factor
