Muchina wepepa wecylinder mold unogona kugadzira mapepa emhando dzese, kubva kuhofisi yakatetepa uye mapepa epamba kusvika kubhodhi gobvu repepa, une mabhenefiti ekuva nyore, kushanda kuri nyore, kushandisa simba shoma, nzvimbo diki yekuisa uye mari shoma yekudyara nezvimwewo. Kunyangwe kumhanya kwemuchina kuri kumashure zvikuru nemuchina wefourdrinier uye muchina wemhando yewaya dzakawanda, uchiri nenzvimbo yawo muindasitiri yekugadzira mapepa yanhasi.
Zvichienderana nehunhu hwechikamu chemould checylinder nechikamu chekuomesa, huwandu hwemamould ecylinder neomesa, muchina wepepa recylinder mold unogona kukamurwa kuita muchina we single cylinder mold single dryer, muchina we single cylinder mold double dryer, muchina we double cylinder mold single dryer, muchina we double cylinder mold double dryer uye muchina we multi-cylinder mold multi-dryer. Pakati pawo, muchina we single cylinder mold single dryer unonyanya kushandiswa kugadzira bepa rakatetepa rine mativi maviri rakaita sepepa repositi nepepa repamba nezvimwewo. Muchina we double cylinder mold double dryer unonyanya kushandiswa kugadzira bepa rekudhinda rine huremu hwepakati, bepa rekunyora, bepa rekuputira nebepa repasi rakakombama nezvimwewo. Bhodhi remapepa rine huremu hwakakura, senge kadhibhodhi jena nebhokisi rinonyanya kusarudza muchina we multi-cylinder mold multi-dryer paper.
