What does a Screen Printing Machine Operator do?
Operates screen machine that folds and bonds edges of vinyl sheets to reinforcing strips and punches holes in strips to form shower curtains: Selects roll of vinyl specified on work order, inserts metal cylinder in roll, positions roll in holding brackets of machine, and turns knobs to secure cylinder. Fills cylinder with air to prevent slippage of roll during machine operation, using airhose. Cuts lead end of vinyl with scissors to straighten end and attaches end to material in machine, using tape. Adjusts guides that fold edges of vinyl and solvent release mechanism that seals folded edges, using handtools. Turns knobs to set heat level of rollers that press and seal folded edges of vinyl. Inserts roll of vinyl reinforcing strip in holder above press of machine, and pushes end of strip onto chain that automatically positions strip for bonding to and reinforcing lead end of vinyl sheet. Pushes button to start machine and measures vinyl in machine to verify width specified on work order, using tape measure. Flips switches to activate feed chains that automatically pull vinyl and reinforcing strip into position under press, and to lower press that cuts, punches holes in, and presses and bonds strips against vinyl to form shower curtains. Observes movement of vinyl through machine and adjusts machine periodically to eliminate detected defects.
