Pneumatic threader for yarn through double twister spindle - has axial bore from below connected to air supply

The end of yarn from the spool is threaded through the shank of double twister spindle, by feeding a compressed gas along an axial bore from below through the spindle. The bore opens out obliquely to the spindle circumference at the level of the outlet for the thread from the upper end of the spindle, into a guide channel much larger in diameter than the outlet for the thread, so as to create a suction in the spindle bore. The gas used is air, and fixed lines with valves and connections beneath the spindle brackets are provided so that compressed air is immediately available when required. The threading of the yarn down the bore of the spindle and out through the support dish takes an appreciable time whether the end is drawn through by a probe or sucked by a bellows. Previous devices for injecting air across the bore at the base of the spindle to suck the thread through, have the objections of complicated and expensive design.

Automatic yarn splicing - has monitor between the spinner and the splicer to trigger the operation through program control according to actual conditions

During an automatic yarn splicing operation, to repair a broken yarn between the spinning and winding stations, it is monitored between the spinning station and the splicer to check the presence of the yarn. When the yarn is detected, it is taken automatically in the spinning operation and/or the splicing action with measures to prevent subsequent faults, or interrupt the yarn splicing or to initiate a new splicing action, to remove a loose yarn and/or generate a fault indication. When it is detected that the thickness or mass of the yarn splice or the yarn lie outside tolerance limits, the yarn is cut upstream of the splicing unit, and the yarn end with the out-of- tolerance length is wound on the bobbin, or the spinner is stopped, and the unacceptable yarn length is drawn from the yarn store or collector and the splicer, and wound, and a fault indication is generated. The unacceptable length is then withdrawn from the bobbin, and cut away before a new splice is formed, and the waste length is sucked clear for removal. ADVANTAGE - The method reduces faults in the yarn splicing operation and increases the number of effective yarn splices to increase the effectiveness of the spinning assembly.

Doubled yarn splicing - has separate splicing stations set up for different types of yarn components

To splice a break in a doubled yarn where, at a spinning station, two yarns of different types are spun simultaneously and are doubled together for winding, they are cut automatically at the doubling point when a break is regisitered in one of the components. The yarn sections are caught by a suction unit and are sepd. without laying in the doubling guide, to be passed to separate splicing stations where each yarn component is spliced with the same type. The doubled yarn at the winding bobbin is carried by a suction tube to a cutter with separate yarn components leading back to a guide in front of the bobbin where they combine. On a correct lie, the separate yarns from the bobbin are each spliced with one of the same type from the spinning station. On an incorrect positioning, the doubled yarn from the bobbin is cut, the components sepd. and the waste removed, and further laid until the sensors register that they are in place. ADVANTAGE - The method allows for the different types of yarn making up the doubled yarn, giving an effective splicing with min. waste.

Upon loosening and disentangling the broken yarn, the suction arrangement (4) is positioned over the cop (5) to suck the broken yarn for a piecing operation.

Threading apparatus

To provide a threading apparatus that can thread yarn (Y) by feeding compressed air when the yarn is fed from a large diameter portion (1a) of a spindle member (1) to a small diameter portion (1b) of the spindle member (1) preceding the large diameter one. A spindle member is divided and a pipe (2) consisting of a filter member is installed in the middle of the spindle, so that when compressed air is injected from the rear end of the spindle having a large diameter toward its tip having a small diameter and preceding the rear end, a suction flow that sucks external air at the rear end is generated while excessive air is discharged to the exterior through the filter member (2), thereby maintaining a yarn feeding air flow in the center of the spindle member (1). Thus, the present invention can provide a threading apparatus that can feed compressed air to thread yarn from the rear end having a large diameter toward the preceding small diameter portion.

Yarn splicing device

本发明涉及一种纱线拼接装置(10)，用于气动接合两个纱线端头，其包括拼接棱柱(23)，该拼接棱柱具有拼接通道(41)，压缩空气能够施加到拼接通道(41)，拼接通道(41)能够在拼接操作期间被盖件(18)关闭。根据本发明，盖件(18)可滑动地安装并且能够通过驱动装置(44)设置成，使得盖件(18)定位在拼接棱柱(23)的拼接通道(41)沿向上方向打开的位置(I)或者拼接通道(41)沿向上方向关闭的位置(II)。

Apparatus for the piecing of a wind-round yarn

The apparatus for the piecing of a wind-round yarn comprises a pair of delivery rollers (1), a following hollow spindle (2) with a tying-thread bobbin, a pair of draw-off rollers (3) and a winding device (4). Arranged between the pair of delivery rollers (1) and the hollow spindle (2) is a housing (5), in which a main channel as well as a fibre suck-off channel and a thread suck-in channel are located. Furthermore, a tube which can interrupt the suction effect of the fibre suck-off channel is mounted movably in the housing. This tube can either be mounted transversely to the main channel and rotatable about its longitudinal axis or be arranged in the main channel axially relative to the latter, rotatable about its longitudinal axis or movable in the longitudinal direction. <IMAGE>
