An apparatus and a method for pasting of plastic film onto workpieces provides for the workpieces to be carried in sequence over a table and between a roller pair; precut sections of the plastic film being delivered by a conveyor cylinder in synchronized sequence to correspond with the workpieces, and a broad-slit nozzle directs a supply of heated air into the roller gap to effect pasting of each film section to a preselected region of the corresponding workpiece. A temperature sensor above the path of the workpieces after leaving the roller gap and a subsequent table temperature sensor provide signals to a control means, whereby a temperature directly after pasting of a pasted region of the workpiece at which a good pasting is performed is determined as a nominal value, and the supply of heated air to the broad-slit nozzle is regulated in response to the signals.
