Kithesis er et værksted, der låser en række dele i en komplet pakke. Det er ikke en lagerliste eller en almindelig materialregningsmaskine: Først beregne, hvor mange kasser der kan forsegles i aften, og derefter sætte mangel, udskiftning, forsamlingsvej, kassekapacitet, stationsbelastning og voksdækning i en løbende lukket sløjfe. De dele, der ikke kan lukkes, skal fortsætte med at gå fremad med manglende billetter, erstatningsrisiko og supplerende impulser, indtil de kan lukkes igen. Lederen læser puls og mangel lys i lobbyen, forhåndsvisning på monteringsbordet, låse partier, og derefter gå på handsker bord efter lager plukke varer, kontrollere veje, gøre den første bekræftelse, og til sidst dække voks forsegling. tomme rammer kan trække stop; Komplete pakker, der allerede er monteret, kan stadig aflukkes halvvejs, og resten returneres til lager og udskrives automatisk. Overvarmede eller mistænkelige partier vil først isoleres på voksplader, og varme sælgere kan flyttes til stationens udgangspunkt ved at gå i skyggen for at forkorte aftens forsendelsesrejse. Efter ankomsten vil suppleringspulsen blive fastlagt på den blokerede ordre, og markeringen kan forsegle flere sæt. Værkstedet finder sted i Hefeistos-værkstedet i Piræus: både mekaniske bremser og hydraulik, men også vedligeholdelse af stensøjler og søjlelamper. Grænsefladen er præsenteret på dansk og er rettet mod dem, der virkelig pakker på bordet, i stedet for dem, der ændrer lageret i tabellen. Åbningen er et værksted, der mangler.
