The apparatus includes an extruder head with an entirely or mainly downwardly directed ejection orifice and two counterrotating rollers with a nip for calibrating the extruded foil. In a feeding device with a vertical supply magazine, a stack of fittings is accommodated and a guiding device is used to guide fittings into a discharge duct extending towards the roller nip. The guiding device is electrically operated and an electrically controlled stop member with an associated fitting sensing element are arranged at the lowermost end of the discharge duct towards the roller nip for accurate control of the supply of fittings to the roller nip through controlled stopping and releasing of the fitting element as well as the monitoring of fittings in the discharge duct. The discharge duct is arranged in such a relationship to the counterrotating rollers that each fitting is supplied from the mouth of the discharge duct to the roller nip by substantially a free fall.
