摘要： On each draft element of a ring spinning frame, two pieces of short-staple roving from the roving bobbin enter into the draft mechanism to be drafted though a guide funnel in parallel, two pieces of filament are fed from the back of the front roller, and combine with two pieces of roving at front jaw respectively. The drafted two pieces of roving and filament are output from the front jaw and enter into the twisting triangle area to be twisted, and then are wound onto a yarn bobbin to produce yarn. Based on the relative position of the two pieces of roving and two pieces of filament, different yarns can be produced. Furthermore, multi-component yarn, such as core structure, wrapped structure, strand-like structure, can be produced on a ring spinning frame. The structure of yarn can be precisely determined. Special fiber yarn can be produced on traditional spinning frame.
摘要翻译： 在环锭纺纱机的每个牵引元件上，从粗纱筒管的两条短裤粗纱进入牵伸机构，通过平行的引导漏斗进行牵引，从前辊的后部进给两根细丝， 并分别与前颚两条粗纱相结合。 将两条粗纱和长丝从前颚输出并进入扭转三角形区域进行扭曲，然后缠绕在纱线架上以产生纱线。 基于两条粗纱和两条长丝的相对位置，可以生产不同的纱线。 此外，可以在环锭纺纱机上制造诸如芯结构，包裹结构，线状结构的多组分纱线。 可以精确确定纱线的结构。 特殊纤维纱可以在传统的纺纱机上生产。

摘要： In the case of a process for producing a twisted yarn from slivers that are drawn to the desired size and subsequently are prestrengthened by means of pneumatic false twisting, it is provided that the fiber ends in the form of helixes are wound around the core with such a steep slope that, during the twisting, the fiber ends that were previously wound around the core are wound off the core as much as possible.

摘要： Disclosed herein is a twisted yarn comprising at least two bundled sheaves of staple fibers, each sheaf having an initial twist of substantially zero, the sheaves of staple fibers being mutually twisted to form the yarn. The coefficient of finishing twist utilization as defined in the specification is at least 150%.Also disclosed is a method of producing a twisted yarn comprising drafting a sheaf of staple fibers, supplying the sheaf to a bundling zone to reduce it to a bundled sheaf having an initial twist of substantially zero, drafting another sheaf in a similar manner, doubling at least two such bundled sheaves of staple fibers, and twisting them together.

摘要： An apparatus and a method for producing a roving package by pretwisting a roving band during winding of the package to produce a one-twist per revolution band layer configuration. A roving band feeding eye is reciprocated with respect to and simultaneously orbited about a mandrel for winding filament containing roving strands thereupon. The winding is accomplished over the end of the mandrel so that a twist is incorporated in each turn of the roving strand for every revolution of the feeding eye. A device is also provided for shifting the winding eye radially outwardly as the diameter of the roving package increases during winding.
