A system, apparatus, and method for coating and curing disposable containers, e.g. cups that are made from .thermoplastic particles, e.g. expandable polystyrene particles (EPS) , and that are coated with a coating, e.g. latex coating. The system comprises a preparation station, a coating station, a curing station, and a container handling station. An apparatus comprising a rotatable wheel is used to position the containers into the several stations. The rotatable wheel contains a plurality of container holding means that consists of vacuum means selectively operable for retaining and releasing the containers relative to the stations and a rotatable platform for selectively rotating the containers to evenly apply and/or dry the coating on the containers and to increase the production rate for coating and/or curing the containers.
Système, dispositif et procédé d'application d'un revêtement et de durcissement de récipients jetables, tels que gobelets faits de particules thermoplastiques (par exemple particules de polystyrène expansé/EPS), et qui sont recouvertes par exemple de latex. Le système comprend un poste de préparation, un poste d'enrobage, un poste de polymérisation et un poste de manutention des récipients. Le positionnement des récipients sur les divers postes se fait au moyen d'un dispositif muni d'une roue. Cette roue comporte une pluralité de dispositifs de tenue des récipients avec mise sous vide qui font tourner sélectivement lesdits récipients au gré des postes de travail, cependant qu'une plate-forme tournante fait tourner sélectivement les récipients dans le but d'uniformiser l'application du revêtement et/ou de durcir les récipients et d'augmenter ainsi la cadence de ces opérations.
