与多步制造工艺相比，D向粘合的纺织品预成型件允许复杂的纤维配置和更有效的部件组装，以通过成形和接合来产生预成型件。然而，这种预制件的先决条件是开发一步纺织品制造工艺。本文介绍了一种新开发的基于可变经纱输送的单步加工解决方案的机器概念，该方案使得在不改变任何硬件的情况下同时生产网状平面和3-D经编粘合纺织品预成型件成为可能。现有的限制和一致的战略发展的一个通用的解决方案，生产不同的和复杂的几何形状的预成型件阐明。设计并介绍了一种新型经纱输送系统，该系统采用数控传动装置和差动落纱装置实现单根经纱输送。通过这一创新，纺织分支从开发新的优质产品中受益，以提高其市场地位，同时充分满足现有的经济挑战。
D stitch-bonded textile preforms allow for complicated fiber configurations and a more efficient component assembly, as compared to the multi-step fabrication process, to create preforms by forming and joining. A prerequisite for such a perform, however, is the devel- opment of a one-step textile fabrication process. This paper presents a newly developed ma- chine concept of a single-step processing solution based on a variable warp yarn delivery, which makes the production of both net-shaped plan and 3-D stitch-bonded textile preforms possible without any hardware changes. Existing constraints and conformable strategies for the development of a universal solution for producing preforms with varied and complex geometry are elucidated. A new warp yarn delivery system employing NC-Drive units for individual warp yarn delivery together with a differential doffing unit was designed and presented herein. With this innovation, the textile branch benefits from extended possibili- ties in the development of new quality products to improve their market positions while suc- cessfully catering to meet the existing economic challenges.
