筒子架是整經機(ji)的組成(cheng)(cheng)部(bu)分(fen)，放置筒子的支(zhi)架。由(you)金屬管(guan)材(cai)或型材(cai)制(zhi)成(cheng)(cheng)的兩個翼架組成(cheng)(cheng)，有矩形(xing)(xing)、矩一V形(xing)(xing)和V形(xing)(xing)多種形(xing)(xing)式。

配有排列均勻的(de)(de)(de)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)插座、導(dao)(dao)紗器、張力(li)裝(zhuang)(zhuang)(zhuang)置(zhi)、斷頭自停裝(zhuang)(zhuang)(zhuang)置(zhi)、信號指示等，部分(fen)新型(xing)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)還(huan)配有換筒(tong)(tong)(tong)(tong)(tong)裝(zhuang)(zhuang)(zhuang)置(zhi)、自動(dong)(dong)打結(jie)裝(zhuang)(zhuang)(zhuang)置(zhi)等。容納筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)數(shu)量因整(zheng)經方式(shi)而異，分(fen)批整(zheng)經機(ji)的(de)(de)(de)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)可容納400~800個(ge)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)，分(fen)條(tiao)整(zheng)經機(ji)則較少(shao)。分(fen)批整(zheng)經的(de)(de)(de)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)固(gu)定(ding)不動(dong)(dong)，為固(gu)定(ding)式(shi)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)；常見的(de)(de)(de)分(fen)條(tiao)整(zheng)經機(ji)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)隨導(dao)(dao)條(tiao)器及定(ding)幅筘移動(dong)(dong)，為移動(dong)(dong)式(shi)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)，新型(xing)分(fen)條(tiao)整(zheng)經機(ji)也采用(yong)固(gu)定(ding)式(shi)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)。筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)退繞(rao)(rao)方式(shi)有軸向(xiang)和(he)徑向(xiang)退繞(rao)(rao)兩種，后者紗線退繞(rao)(rao)張力(li)波動(dong)(dong)大，已很少(shao)應用(yong)。連續式(shi)整(zheng)經”使用(yong)復(fu)式(shi)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)，分(fen)有工(gong)(gong)作筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)和(he)預備筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)；先進的(de)(de)(de)整(zheng)經機(ji)采取間(jian)歇式(shi)整(zheng)經”，配用(yong)單式(shi)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)，只(zhi)有工(gong)(gong)作筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)。為縮短間(jian)歇式(shi)整(zheng)經的(de)(de)(de)停機(ji)換筒(tong)(tong)(tong)(tong)(tong)時間(jian)，產生(sheng)了多種新型(xing)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)，有循環(huan)鏈(lian)式(shi)V形筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)、回(hui)轉立柱(zhu)式(shi)矩形筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)、組合車式(shi)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)等，部分(fen)筒(tong)(tong)(tong)(tong)(tong)子(zi)(zi)(zi)(zi)(zi)架(jia)(jia)(jia)還(huan)裝(zhuang)(zhuang)(zhuang)有自動(dong)(dong)打結(jie)裝(zhuang)(zhuang)(zhuang)置(zhi)，使換筒(tong)(tong)(tong)(tong)(tong)操作的(de)(de)(de)自動(dong)(dong)化程度提高。
