Umshini wephepha ohlobo lwe-Fourdrinier wasungulwa indoda engumFulentshi u-Nicholas Louis Robert ngonyaka ka-1799, ngemva nje kokuba indoda eyiNgisi uJoseph Bramah isungule umshini wohlobo lwe-cylinder mold ngonyaka ka-1805, waqala ukuphakamisa umqondo kanye nemifanekiso yephepha lokubumba i-cylinder ekwakhekeni kwakhe. ilungelo lobunikazi, kodwa ilungelo lobunikazi lika-Bramah alilokothi ligcwaliseke. Ngonyaka ka-1807, indoda yaseMelika okuthiwa uCharles Kinsey yaphinde yaphakamisa umqondo wokwakhiwa kwephepha lesikhunta futhi yathola ilungelo lobunikazi, kodwa futhi lo mqondo awusoze waxhashazwa futhi usetshenziswe. Ngonyaka ka-1809, indoda eyiNgisi okuthiwa uJohn Dickinson yahlongoza umklamo womshini wokubumba isilinda futhi yathola ilungelo lobunikazi, ngawo lowo nyaka, umshini wokuqala wokubumba isilinda wasungulwa futhi wafakwa ekukhiqizeni emshinini wayo wokugaya amaphepha. Umshini wokubumba we-cylinder ka-Dickinson uyingqalabutho kanye nesibonelo se-cylinder yangaphambili, uthathwa njengomqambi wangempela womshini wephepha wohlobo lwesilinda ngabacwaningi abaningi.
Umshini wephepha we-cylinder mold ungakhiqiza zonke izinhlobo zephepha, kusukela ehhovisi elincanyana nephepha lasendlini kuya ebhodini lephepha eliwugqinsi, unezinzuzo zesakhiwo esilula, ukusebenza okulula, ukusetshenziswa kwamandla okuphansi, indawo yokufaka encane kanye nokutshalwa kwezimali okuphansi njll Ngisho nomshini osebenzayo ijubane lingemuva kakhulu komshini wohlobo lwe-fourdrinier nomshini wohlobo lwezintambo eziningi, isenayo indawo yayo embonini yanamuhla yokukhiqiza amaphepha.
Ngokwezici zesakhiwo sesigaba se-cylinder mold kanye ne-dryer section, inani le-cylinder mold and dryer, umshini wephepha le-cylinder mold ungahlukaniswa ube umshini owodwa womshini wokomisa i-cylinder, umshini owodwa womshini wokomisa i-cylinder, umshini wokomisa we-cylinder ophindwe kabili, umshini wokomisa isilinda ophindwe kabili kanye nomshini wokomisa owenziwe ngamasilinda amaningi. Phakathi kwazo, umshini wokomisa isikhunta esisodwa usetshenziswa kakhulu ukukhiqiza iphepha elicwebezelayo elinohlangothi olulodwa njengephepha leposi kanye nephepha lasendlini njll. Umshini wokomisa ophindwe kabili we-cylinder usetshenziswa kakhulu ukukhiqiza iphepha lokuphrinta elinesisindo esiphakathi, iphepha lokubhala, ukugoqa. iphepha nesisekelo sephepha eliwuthayela njll. Ibhodi lephepha elinesisindo esikhulu, njengekhadibhodi elimhlophe nebhodi lebhokisi ngokuvamile likhetha umshini wephepha onama-cylinder multi-cylinder multi-dryer paper.
