Plastic sheet uye bhodhi kugadzira michina yakakosha muindasitiri yekugadzira mapurasitiki. Dhizaini yayo haingokanganisa kugadzirwa kwakanaka chete asiwo kuchengetedzwa kwekushanda uye kurongeka kweiyo workshop marongero. Mapepa emazuva ano epurasitiki nemidziyo yekugadzira bhodhi kazhinji ane extruder, die, three-roll calender, traction device, cutting system, uye winding or stacking unit. Izvi zvikamu zvakabatanidzwa zvakasimba kuti zvigadzire mutsara wekugadzira unoenderera.
Pakazere, pepa repurasitiki uye zvigadzirwa zvekugadzira bhodhi zvinowanzotora modular dhizaini, ine mayuniti anoshanda akarongwa mutsetse kufambisa kuyerera kwezvinhu uye maitiro ekugadzirisa. Iyo extruder, sechikamu chepakati, inongomira kana yakarerekera silinda chimiro chine yakakwirira{{1}torque mota uye siruuru chaiyo. Imba yacho yakavharidzirwa nesimbi yakasimba ine ngura-inodzivirira pamusoro, zvichiita kuti pave neruvara rwegireyi kana kuti sirivheri{4}. Iyo inofa, iri kumagumo eiyo extruder, yakati sandara muchimiro, iine yakanyatsogadzirirwa yemukati yekuyerera nzira kuti ive nechokwadi kunyangwe kugovera kwepurasitiki kunyungudika. Iyo compact dhizaini inoita kuti zvive nyore kupatsanura nekuchengetedza.
Iwo matatu-roll calender, anowanikwa aripadhuze nemusoro wekufa, ane maviri akaiswa roller, imwe kumusoro neimwe pazasi, uye inogadzirika pakati roller, yakarongwa yakachinjika. Maroller anotsvedzerera uye anoshingirira kupisa-, uye anoshandiswa kutonhodza nekuumba mapepa epurasitiki. Iyo traction mechanism uye yekucheka sisitimu inogadziriswa inogadziriswa zvinoenderana nezvinodiwa zvekugadzira. Mavhiri ekudhonza anowanzo simbi ine cylindrical simbi ine anti-inotsvedza mitsetse, ukuwo mablades ekucheka anogona kunge ari disc-mhando kana kuti flat-akachekwa, akaiswa pamabhuraketi anogona kuchinjika. Iyo yekudzosera unit inowanzo cylindrical reel ine otomatiki tension control system kuti ive yakatsetseka pepa rekudzoserwa.
Pamusoro pezvo, michina yechizvino zvino inosimbisa-magadzirirwo ane hushamwari. Chishandiso chinowanzo wanikwa kune rimwe divi remuchina, uchishandisa sikirini yekubata kana kubairira-mabhatani zvidhiraivho kuti zvitarisire zviri nyore. Iyo yakazara dhizaini inoyera mashandiro uye chengetedzo, uye mamwe mamodheru akashongedzerwa neakavharira ekudzivirira kana yekumisikidza yekumisa zvishandiso kutevedzera indasitiri zviyero. Dhizaini yemapepa epurasitiki nemidziyo yekugadzira bhodhi inogara ichigadziridzwa kuti isangane nezvinodiwa zvekugadzirwa kwakanaka uye zvine hushamwari.
