摘要:
A device for joining a large number of threads on a single frame. Each of a plurality of thread clamps has a guide tube communicating with a vacuum duct. A carriage for carrying a thread joining system is arranged on the frame. As the carriage moves along the frame to a selected position a thread clamp is released and the released thread is moved by a pivot threading arm to the joining system.
摘要:
A thread processing machine, in particular an embroidering machine, is provided with a thread joining device, which has a whirl chamber and a compressed air nozzle, in which two threads of different color, one used after the other, are joined together by compressed air vortex connection of their filaments, after which they are drawn through the needle.

There is provided a process for inspecting a splicer provided for splicing yarn ends upon the occurrence of yarn breakage or the like in an automatic winder, the process comprising the steps of, after splicing yarn ends, taking up the spliced yarn at a low speed and restraining the yarn on the yarn supply side to impart a predetermined tension to the yarn, detecting whether yarn breakage indicative of malfunction of the splicer has occurred, and, if the yarn breakage indicative of malfunction of the splicer has not occurred, cutting the spliced yarn, and re-splicing the yarn ends of the yarn thus cut.
摘要:
In doubling two yarns to wind it on a package, a splicing part is displaced between a splicing part of one yarn and a splicing part of the other yarn so as to present a deviation in phase when the yarns are doubled, single yarns are used to make splicing, after which the yarn is wound on the package.
摘要:
An end portion of an elongate member of generally cylindrical form, such as an optical fiber, is placed in a predetermined position utilizing a substrate having a surface that is defined by a generatrix that is a straight line, e.g. a flat surface. A foil of flexible material is secured to the surface of the substrate and defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of the surface and has a first portion of substantially uniform cross-section adapted to receive an end of the elongate member in closely fitting relationship and also has a second portion that tapers towards the first portion. The end portion of the elongate member is inserted into the first portion of the passageway by way of the second portion thereof.
摘要:
An improved, reduced tension, automatic yarn sampling device, and a process for its use, is disclosed. The device exerts significantly lower tension on multifilament yarn thread than that tension typically required to approach the deformation yield point of partially oriented yarn.
摘要:
The invention relates to a process for piecing on a machine for producing core spun yarns, said process comprising the following successive steps of: taking off a broken end of a core spun yarn formed from the receiving member, (for example a reel); exposing the internal core of said yarn over a pre-determined length; connecting the core thus exposed with the end of the elementary core yarn; introducing the bared core into the fiber distribution system; distributing the fibers on the core downstream of the point of join; and advancing and winding normally. The invention also relates to a device for carrying out this process.
摘要:
A joint between two textile materials in web form, one of them preferably being a plurality of parallel yarns forming a monolayer or multilayer sheet, and the other one a fabric. The joint is an adhesive or heat sealed bonding member which is equipped at least on one of its surfaces with a heat shield. The joint is flexible, thin, tear and heat resistant, not attacked by chemical reagents, solvents or vapors. It can be formed in a novel apparatus for heat sealing by means of heat sealable strips which are reinforced by heat resistant materials and which are heat sealed together across the yarn sheet.
摘要:
This invention relates to a method and an apparatus for avoiding untwisting during the formation of a binding of two fiber bundles. The rotational direction of deformation members acting on the fiber bundles is selected to be different in different groups of deformation members in order to reproduce or to increase the original twist during the binding operation.
摘要:
A yarn knotting operation control apparatus for an automatic winder including a plurality of winding units and a yarn knotting device comprises one air conduit for supplying suction air stream used for performing the yarn knotting operation, a blower connected to the air conduit, devices for detecting whether or not the normal travel of yarns is performed in the respective winding units, devices for initiating the yarn knotting operation and a control device having a memory device for storing signals from the detection device and means for putting out signals of the yarn knotting operation.
