Abstract

1449068 Leno motions; travelling wave shedding looms WIRKMASCHINENBAU KARL-MARX-STADT VEB 26 April 1974 [1 June 1973] 18367/74 Heading D1E A leno selvedge shedding motion for a travelling wave shedding loom with partial heald frames comprises standard half healds 5 fixed to a partial frame 2 to shed therewith and leno healds 7 which are shogged by a cam 15 but are not shed. The height of the leno healds is adjustable and they are movable on the loom to provide different width fabrics and also to provide more than one fabric per loom width.

Description

ного перемещени в горизонтальной плоскости состоит из закрепленного винтом 10 на параллельном ремизкам ва.чу II назового кулачка 12 и смонтированного на раме стайка 13 двзплечего рычага 14. На одном плече рычага закреплен держатель 7, иа другом палец 15, контактирующий с пазовым кулачком 12.horizontal displacement consists of a screw 10 fixed on the parallel shaft shaft II of the national cam 12 and mounted on the frame a flock 13 of the double arm 14. On one arm of the lever there is a holder 7, and the other finger 15 is in contact with the groove cam 12.

Работает механнзм следующим образом .Mechanism works as follows.

Ремизка 5 из своего верхнего положени перемещаетс вниз, увлека за собой держатель 1 с иглами 2 стоевых нитей 4. Между стоевыми иит ыи 4 и иеревивочпыыи нит ми 6 образуетс зев, в который 1П,ро:клалываетс уточна нить (на чертеже ке показана).Далее ремизка 5 и стоевые нити 4 возвращаютс в верхнее положение, в это врем пазовый кулачок 12 поворачивает рычаг 14 п иглы 8 с перевивочными нит ми 6 перемещаютс в горизонтальной плоскости и измен ют свое положение относичельио игл 2 со стоевыми нит ми 4. В это :врем происходит ирокладка следующей уточной нити, iHO вне нитей 4, 6 -ц 1вслед за эти-.м ремлзка 5 оп ть (шускаетс вниз, вновь образуетс зев между нит ми 4, 6, в кото рый прокладываетс треть ут0ч«а иить. Положение нитей 4, 6 в горизонтальной плоскости в данном случае иное, чем в случае первой прокладки, т. е. нити 4, 6 образуют с нечетными уточными нит ми перевивочное иереплетение.Remizka 5 moves down from its top position, the holder 1 with needles 2 stitched threads 4 is carried along. Between the stitches 4 and 4 and the seam 6 there is a mouth, in which 1H, ro: put the weft thread (shown on the drawing). Further, heddle 5 and the staple yarns 4 return to the upper position, at which time the slot cam 12 rotates the lever 14 and the needles 8 with the winding threads 6 move in a horizontal plane and change their position relative to the needle 2 with the staple threads 4. In this: time happens and the next lay iHO out of the threads 4, 6 -C 1 after these 5 strap 5 again (goes down, again forms the jaws between the threads 4, 6, in which a third of the lines is laid out. The position of the threads 4, 6 in the horizontal plane, in this case, different than in the case of the first gasket, i.e., threads 4, 6 form a stitching loop with odd weft yarns.

Наличие винта 10, служащего дл креплени кулачка 12 к валу 11, позвол етThe presence of a screw 10 serving to fasten the cam 12 to the shaft 11 allows

измен ть фазу смещени стоевых нитей 4. Использованпе пзобретени позволит повысить качество кромки, а наличие регулировки в механизме позволит установить его в любом месте бесчелночного ткацкого станка, а также ткацкого станка с волнообразно подвижным зевом.change the displacement phase of the yarn. 4. Use of the invention will improve the quality of the edge, and the presence of the adjustment in the mechanism will allow it to be installed in any place of the shuttleless loom, as well as the weaving machine with a wave-like movable throat.

Invention Formula

The mechanism for forming the hem of the levity weave on the shuttleless loom, containing a pair of needles with eyes for stitches, fastened in a holder with a means of reciprocating movement in the vertical plane, and a thread guide for the leno threads, having a means of returning and moving in the horizontal plane, about in order to increase the quality of the edge, the thread for the yarn has a holder and a pair of needles with eyelets fixed in it

the threads, and its reciprocating alternating means consists of a slot cam and a edging: kthi, guiding with it with one arm and two shoulders mounted on the machine frame, while the thread guide for the stitching threads is fixed on the other arm of the lever.
