We designed and made a circular loom of Fayolle-Ancet type with electro-magnetically operated shuttles, replacing rectilinear motion of plain looms by circular and continuous motion with several shuttles running simultaneously. The warp yarns, with equal tension from two beams located at both sides of the loom, pass upward through circularly disposed distributing reeds, enter two harnesses running horizontally in radial directions and then pass through a horizontal stationary reed on which there are four...

We designed and made a circular loom of Fayolle-Ancet type with electro-magnetically operated shuttles, replacing rectilinear motion of plain looms by circular and continuous motion with several shuttles running simultaneously. The warp yarns, with equal tension from two beams located at both sides of the loom, pass upward through circularly disposed distributing reeds, enter two harnesses running horizontally in radial directions and then pass through a horizontal stationary reed on which there are four shuttles running simultaneously. The harnesses are controlled by central cams. Through their inward and outward radial motions, the harnesses alternately open and close the shed of the warp yarns to let the shuttle pass through. Each shuttle is held in position by a piece of electromagnet, which drives it through the warp yarns. The usual beating up motion of the reciprocating slay is also replaced by the continuous circular motion of a specially designed spiked-wheel, disposed at an inclined angle to the yarn, for laying and tightening the pick (weft). The circular or tubular shaped fabric thus formed is then flatened and received on a roller placed on the upper part of the loom. The chief defect we found is that the shuttles very often run out of way. We are trying to make further improvements.

圆型織機以圓運動代替了普通平型織機的往復運動,是一個革命性的改進。我所設計的圓型織機已由本院金工埸試製成功,兹介紹其基本構造原理如下: 經紗盤頭用兩倜,分列左右,合用一個調整螺絲來調整兩面的張力,維持其相等。經紗自盤頭引出,向上穿過圆形分布筘,就排列成圆筒形,然後通過開口綜絲而穿上靜止筘;筘上有圓梭四只。綜絲開口,由凸输控制;凸输迴轉時,綜絲卽引導經紗交替開閉,讓四只梭子带着緯紗依次相接通過其開口而前進。梭子是藉電磁鐵吸住在兩對羅拉上而推送前進的,並不吸住在電磁鐵面上,以避免拖住經紗。打緯運動,用一倾斜有刺輸跟随於梭後,将閉口後織口内的緯紗壓緊,也以圆運動代替了—般往復的打緯運動,可以减少一般打緯筘對於經紗的来回擦傷。又因開口比一般平型織機爲小,所以經紗張力的變化也小,可以减低經紗的断頭率。織成的圆筒形布,撑平後向上捲取。目前階段主要缺點爲梭子易脫出,當待繼續改進。

The method for increasing the total draft on the cotton ringframe by using a single controlling flume is described. The total draft of the ordinary 3-line double apron system is increased to about 40 by means of an improved fiber movement control in the back draft zone (or the break draft zone as it is usually called). A flume is inserted between the second and third rollers for this purpose, and the whole mechanism remains almost unchanged exceptroller weightings and settings. The flume has an open channel...

The method for increasing the total draft on the cotton ringframe by using a single controlling flume is described. The total draft of the ordinary 3-line double apron system is increased to about 40 by means of an improved fiber movement control in the back draft zone (or the break draft zone as it is usually called). A flume is inserted between the second and third rollers for this purpose, and the whole mechanism remains almost unchanged exceptroller weightings and settings. The flume has an open channel shape and its width varies with the count of the yarn spun. It is found that a channel width of 25 mm. is suitable for spinning yarns of 21-32 English counts. The mechanism performs well in spinning, as the properties of the yarn spun are satisfactory. The shape of the flume and its positions relative to the 2nd and 3rd rollers have great influence in spinning. It is found that the distance between the second roller center and the front edge of the flume should be within 10-12 mm., the bottom of the channel at the rear end should be leveled 2 mm. above the gripping points at the second and third rollers, while that at the front edge, 1 mm. below. So the flume should be inclined forward to the roller stand. The flume can control the fiber movement better because it gives good contact between fibers in the drafting zone, provides required inter-fiber pressures at different sections, and makes the width of the strand narrow enough after drafting so that it makes continuous drafting possible.

本文对在棉纺精纺机上利用控制管加大牵伸倍数的可能性进行了讨论,并进行了纺纱试验。文中指出,在日东式牵伸机构的后区中,加装控制管,可使精纺机的总牵伸倍数增大至40倍左右。文中包括32支(英制)细纱的试验结果。文中第二节对控制的设计要求进行了讨论。控制管的尺寸、安装位置纺纱条件及试纺的成纱品质叙述在第三节中。第四节对控制管的作用及加控制管后牵伸区域中的摩擦力分布等进行了初步的理论探讨。文中指出,所用的控制管为直槽形,槽的宽度在2.5毫米左右,控制管须自前向后倾斜。

This paper is intended to discuss-the deviation in labor-production rates, resulting from the prevailing calculating methods used in cotton mills. A statistical unit, based on the ratio of labor consumption in cotton yarns of different counts, is derived from careful analysis and calculations. Insomuch as it eliminates the above deviations, it will furnish comparatively accurate data referring labor-production rates. Meanwhile, this criterion will also be of some use to the fixing of price ratio of various...

本文研究棉纺企业现行各种方法计算劳动生产率指标中所产生的品种差异问题。“劳动折合产量”就是通过分析和计算方法,求出各种纱支的费工比例,从而制定出来的一种统计指标。这种单位可以消除计算中发生的品种差异,使劳动生产率比较正确地表现出来,同时可作制订各种棉纱比价的参考。
