Zvikamu zvekutanga zvemichina yekugadzira mapepa zvichienderana nekurongeka kwekugadzirwa kwepepa zvakakamurwa kuita waya, chikamu chekudzvanya, pre drying, mushure mekudzvanya, mushure mekuomesa, calendering muchina, muchina wekutenderedza mapepa, nezvimwewo. Maitiro acho ndeekunyorovesa mvura inobuda mu pulp ne headbox muchikamu che mesh, kudzvanya muchikamu chekudzvanya kuti pepa rive rakafanana, kuomesa usati waoma, wobva waisa press pa size, wobva waisa dryer drying treatment, wobva washandisa presser kukwenenzvera bepa, uye pakupedzisira kugadzira pepa guru rinotenderera kuburikidza ne paper reel. Maitiro akajairika ndeaya anotevera:
1. Chikamu chekubvisa tsvina: kusarudzwa kwezvinhu zvisina kugadzirwa → kubika nekupatsanurwa kwefaibha → kuwacha → kucheneswa → kuwacha nekuongorora → kuomesesa → kuchengetera nekuchengetedza.
2. Chikamu chewaya: Pulp inoyerera ichibuda mubhokisi remusoro, yakapararira zvakaenzana uye yakarukwa pamould yesilinda kana chikamu chewaya.
3. Chikamu chekudzvanya: Bepa rakanyorova rinobviswa pamusoro pemambure rinoendeswa kune roller ine felt yekugadzira mapepa. Kuburikidza nekubuda kweroller uye kunyudzwa kwefelt nemvura, bepa rakanyorova rinowedzera kuoma mvura, uye bepa racho rinova rakaoma, kuitira kuti pepa riwedzere kunaka uye simba rayo riwedzere.
4. Chikamu chekuomesa: Nekuti hunyoro hwepepa rakanyorova mushure mekudzvanya huchiri hwe52% ~ 70%, hazvichakwanisike kushandisa simba remagetsi kubvisa hunyoro, saka rega bepa rakanyorova ripfuure nepamusoro penzvimbo dzakawanda dzinopisa dzekuomesa bepa kuti riome.
5. Chikamu chinomonera: Chipenga chinomonera chinogadzirwa nemuchina unomonera pepa.
