Sheet fixing method

Abstract

The invention discloses a sheet fixing method. The sheet fixing method comprises the following steps that S100, a device, a controller, at least two vacuum manifolds and a device used for vacuumizingthrough inlets and a permeable support surface are provided, wherein the device is provided with a permeable support surface connected to a frame, the controller is in communication with the device and used for storing data in a machine-readable format corresponding to a work operation to be performed on a work material, the at least two vacuum manifolds are connected to the frame and spaced apartrelative to each other, and each manifold defines at least one vacuum inlet; and S200, at least one layer of sheet-shaped working material located on the support surface is provided. Each vacuum manifold defines at least one vacuum inlet, the vacuum device draws vacuum through the vacuum inlets and retains the working material on the permeable support surface through the permeable support surface. In this way, any undesirable movement of the work material relative to the support surface during performance of the work operation is prevented.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a sheet fixing method. Background technique [0002] Working operations are usually carried out on multiple layers of sheet-like work material, for example, in the mass production of clothing, pattern pieces are usually cut from multiple layers of fabrics that are spread out one surface after the other on a support; To facilitate clean and precise cutting, the layers of work material (often referred to as layup) must be held sufficiently in place on the support surface during the performance of the cutting operation; failure to do so can cause the layers of fabric to move relative to each other, adversely affecting the cutting operation performance; [0003] Typically, the pattern is cut from the cut using a so-called cutting table, which usually includes a permeable, usually conveyor belt, cutting surface and a movable cutting head passing through the support surface...

AI Technical Summary

Problems solved by technology

[0004] A difficulty sometimes encountered when employing a single centrally located vacuum manifold is that portions of the work material located away from the manifold tend not to be adequately retained by the vacuum; this insufficient retention can lead to movement of the work material during work operations, and Produces inaccurately cut gobos; this problem is further exacerbated when the width of the cutting table increases, for which a method for securing the sheet is proposed
