Introduction

GB/T 30420 provides common terms used in the design, production and use of different types of sewing machinery based on classification principles and applications:

With definitions, GB/T 30420 is planned to be divided into 4 parts:

— Part 1: General terms: The purpose is to define the general terminology of sewing machinery, and to provide an overview of the main types, products, and general concepts of sewing machinery:

To clarify the terminology of the concept, its mechanism, devices and performance:

— Part 2: Embroidery machine terminology: The purpose is to define the terminology of embroidery machines for sewing machinery, and to introduce the common terms and main products of embroidery machines:

The terminology of product, mechanism, device, control system, operation and pattern production is clarified:

— Part 3: Terminology of spreading and cutting equipment: The purpose is to define the terminology of cloth spreading and cutting equipment of sewing machinery, and to define the terms of cloth spreading and cutting equipment:

Common terms, main types, products, institutions, devices and operation terms are clarified:

— Part 4: Functional component terminology: The purpose is to define the terms of functional components of sewing machinery, and to introduce common terms and terms of functional components:

Main product terms are clarified: Sewing Machinery Terminology Part 3: Spreading and cutting equipment terminology

3 Spreading equipment

3:1 Basic terminology 3:1:1 cloth-spreading Lay the fabric evenly according to the set length and number of layers: 3:1:2 one-waycloth-spreading single pull Spread the fabric from the required length to the initial position and cut it, then return to the required length before spreading again, ensuring that the fabric always remains facing forward:

Spreading (3:1:1) form with top or reverse side up: Note: As shown in Figure 1:

Figure 1 Schematic diagram of one-way spreading 3:1:3 two-waycloth-spreading double pull Fold the fabric back and forth between the initial position and the required length position, so that the front and back sides of the fabric form layers facing each other:

The form of spread (3:1:1) in which the front and back sides are opposite:
