ELI5: How do adhesive factories (super glue, caulking, etc...) prevent their machines from seizing up with dried glue during production?

When the glue is running in the pipes it's usually not exposed to air and it spends very little time in the tube so it can't clog up. These factories might be running the filling machines 24/7 or when the machine is turned off, they run a solvent through the pipes to clean the left-over glue.
