Koob dhia thiab xaws ceev ceev

Ntawm cov tshuab xaws voj voog, kev tsim khoom ntau dua cuam tshuam nrog kev txav koob sai dua vim yog qhov nce ntxiv ntawm cov khoom noj khoom haus thiab ntawm lub tshuabkev sib hloov ceevNtawm cov tshuab xaws ntaub, lub tshuab tig ib feeb yuav luag ob npaug thiab tus lej ntawm cov khoom pub tau nce kaum ob npaug dhau 25 xyoo dhau los, yog li ntau txog 4000 txoj kab ib feeb tuaj yeem xaws rau ntawm qee lub tshuab yooj yim, thaum ntawm qee lub tshuab hose ceev ceev seamlessqhov ceev tangentialntawm cov koob txhaj tshuaj tuaj yeem ntau dua 5 meters ib ob. Txhawm rau kom ua tiav qhov kev tsim khoom no, kev tshawb fawb thiab kev txhim kho tau tsim nyog rau hauv tshuab, cam thiab koob tsim. Cov ntu kab rov tav cam tau raug txo kom tsawg kawg nkaus thaum cov koob hooks thiab latches tau raug txo kom me me txhua qhov chaw ua tau kom txo qhov dav ntawm kev txav ntawm koob txhaj tshuaj ntawm cov ntsiab lus clearing thiab knock-over. 'Koob txhaj tshuaj dhia' yog qhov teeb meem loj hauv kev kub ceev tubular tshuab knitting. Qhov no yog tshwm sim los ntawm lub koob txhaj tshuaj raug kuaj xyuas tam sim ntawd los ntawm kev cuam tshuam ntawm kev ntaus lub ntsej muag sab saud ntawm lub cam-throw tom qab nws tau nrawm dua ntawm qhov qis tshaj plaws ntawm lub koob txhaj tshuaj. Lub sijhawm no, inertia ntawm lub taub hau koob yuav ua rau nws co ua rau nws tawg; kuj lub cam-throw ua pitted hauv seem no. Cov koob txhaj tshuaj hla dhau hauv seem miss raug cuam tshuam tshwj xeeb tshaj yog vim lawv cov butts kov qhov qis tshaj plaws ntawm lub cam xwb thiab ntawm lub kaum ntse ntse uas ua rau lawv nrawm nrawm heev. Txhawm rau kom txo qhov cuam tshuam no, lub cam sib cais feem ntau yog siv los coj cov butts no ntawm lub kaum ntse ntse dua. Cov qauv du ntawm cov cam tsis-linear pab txo cov koob dhia thiab ua tiav qhov cuam tshuam ntawm cov pob tw los ntawm kev ua kom qhov sib txawv ntawm cov xov thiab cov cams pov rau saum toj kom tsawg kawg nkaus. Vim li no, ntawm qee lub tshuab hose lub cam pov rau saum toj yog kho tau kab rov tav nrog rau cov cam cam kho tau ntsug. Lub Tsev Kawm Ntawv Reutlingen ntawm Kev Siv Tshuab tau ua ntau qhov kev tshawb fawb txog qhov teeb meem no thiab, vim li ntawd, Groz-Beckert tsim ib qho kev tsim tshiab ntawm koob latch nrog lub qia zoo li meander, qhov profile qis du, thiab lub hook luv dua rau cov tshuab knitting voj voog ceev ceev. Cov duab meander pab tshem tawm qhov cuam tshuam ua ntej nws mus txog lub taub hau koob, uas nws cov duab txhim kho kev tiv thaiv kev ntxhov siab, ib yam li cov profile qis, thaum lub latch zoo li maj mam tsim los qhib qeeb dua thiab tag nrho rau ntawm qhov chaw cushioned tsim los ntawm kev txiav ob chav.

Cov khaub ncaws sib deev nrog cov haujlwm tshwj xeeb

Kev tsim kho tshiab ntawm tshuab/kev siv tshuab

Cov pantyhose ib txwm ua los ntawm kev siv cov tshuab knitting ncig. Cov tshuab RDPJ 6/2 warp knitting los ntawm Karl Mayer tau pib tsim xyoo 2002 thiab siv los tsim cov ris tsho seamless, jacquard-patterned thiab cov pantyhose ntses-net. Cov tshuab knitting MRPJ43/1 SU thiab MRPJ25/1 SU jacquard tronic raschel los ntawm Karl Mayer muaj peev xwm tsim cov pantyhose nrog cov qauv lace thiab cov qauv zoo li nyem. Lwm yam kev txhim kho hauv cov tshuab tau ua los txhawb kev ua haujlwm zoo, kev tsim khoom, thiab pantyhose zoo. Kev tswj hwm ntawm qhov sheerness hauv cov ntaub ntawv pantyhose kuj yog lub ntsiab lus ntawm qee qhov kev tshawb fawb los ntawm Matsumoto et al. [18,19,30,31]. Lawv tau tsim ib qho kev sib xyaw ua ke ntawm kev sim knitting uas ua los ntawm ob lub tshuab knitting ncig sim. Ob ntu xov paj npog ib leeg tau muaj nyob rau ntawm txhua lub tshuab npog. Cov xov paj ib txheej tau tsim los ntawm kev tswj cov qib npog ntawm 1500 twists ib 'meter' (tpm) thiab 3000 tpm hauv cov xov paj nylon nrog qhov sib piv ntawm 2 = 3000 tpm / 1500 tpm rau cov xov paj polyurethane tseem ceeb. Cov qauv pantyhose tau xaws hauv qab lub xeev tas li. Qhov sheer siab dua hauv pantyhose tau ua tiav los ntawm qib npog qis dua. Cov qib npog tpm sib txawv hauv ntau thaj chaw ceg tau siv los tsim plaub qhov qauv pantyhose sib txawv. Cov kev tshawb pom tau qhia tias kev hloov pauv cov xov paj ib txheej npog hauv cov ceg muaj kev cuam tshuam loj rau qhov zoo nkauj thiab qhov sheerness ntawm cov ntaub pantyhose, thiab tias lub kaw lus sib xyaw ua ke tuaj yeem txhim kho cov yam ntxwv no.
