退绕

In the case of warping, this means that the balloon ing of the yarn coming from the creel package must be controlled.

这就意味着，在整经过程中，对从筒子上退绕下来的纱线形成的气圈要加以控制。

This zone merely consists of a creel, which holds the old package in an optimum position for unwinding.

该区只包括一个筒子架，卷装在筒子架子上处于有利于退绕的最佳位置。

Through the analysis of the movement process of S-twist yarn unwound on the surface of the bobbin, the article has solved end-breakage and raveling problems when the yarn is unwound.

通过对S捻纱退绕时在筒子表面运动过程的研究分析，解决了该种纱线在退绕时表面常常出现断头和乱纱的问题。

Yarn unwinding is a key process in textile production systems.

纱线的退绕是纺织生产中重要的一环。

Before thinking about winding a specified number of yarns on a beam, first consider the problem of positioning the package from which the yarn is taken in such a manner so as to facilitate the removal of yarn.

在将特定数目的纱线卷绕到经轴上之前，首先应考虑筒子的位置要便于纱线的退绕。

The fourth chapter talks about the weft carrier, in this part, we mostly introduce the big gripper shuttle in the comparative way and not only analyze the structure but also analyze the stress of the fatigable parts. In the fifth chapter, the shuttle box is our research emphasis, we start with the design principle and analyze its structure and the logic of the action of the parts. The sixth chapter discusses the shoot mechanism, builds its theory model and analyzes its law of motion from the view of kinematics and kinetics during the wefting. And then, we can consider the hydraulically shoot mechanism and comprehend its principle and some special parts. Subsequently, the content is about the flying of a shuttle, because the course of the flying of a shuttle is very complex, it is necessary to study the shuttle according to mechanics and to analyze its course of motion and its change of speed from the view of energy.

第五章谈的是梭箱，这部分从梭箱的设计原理入手，从结构的角度对梭箱进行分析，考虑到梭箱上各执行件间的动作存在一定的逻辑关系，还对执行件动作时间与控制作出论述，从中可以看出重型宽幅织机所独有的特性；第六章论述投梭机构，先构造出投梭机＿重型宽幅织机引纬机构与梭箱的设计＿构的弹性理论模型，从动力学的角度剖析投梭规律，随后分析液压式投梭的工作原－－理和一些特型元器件；第七章论述梭子的飞行运动，考虑到梭子飞行运动的复杂性，我们把梭子飞行运动划分为三个阶段，然后分阶段介绍其运动规律，在对梭子进行＿运动分析的同时还详细分析它的受力情况，在这一章的最后，我们对影响梭子飞行＿的因素也作出了讨论；顺沿这一过程，即是第八章对制梭机构的论述，在这一部分，、主要研究制梭过程与制梭力的情况，同梭子飞行过程一样，制梭过程也分为三个阶段，就每个阶段而言，我们都对其进行受力与运动方面分析，同时也就一些容易出现的问题作出讨论；最后两章是对纬纱交接机构和纬纱的退绕与张力控制作出讨＿论，鉴于这两部分不存在复杂的动力学方面的问题，论述重点便放在结构与原理的分析上面，包括分解纬纱交接机构，解析其动作过程，介绍储纬与纬纱张力的一些情况。
