Abstract
An applicator for direct or indirect application of a liquid or pasty medium on a traveling material web includes a support beam, a mating roll opposing the support beam, and a doctor element extending across the width of the mating roll and detachably fixed on the support beam via a holder. The holder includes an actuator and a pressure apparatus operable and brought in contact (K) with the doctor element by the actuator, for pressing the doctor element on an abutment surface. The lever type pressure apparatus is disposed in a region between the mating roll and the support beam, and includes at least one elastic spring element acting directly or indirectly on the lever type pressure apparatus, against the reset force of which spring element acts the actuator upon its activation, and which spring element, upon deactivation of the actuator, lifts by its reset force the contact (K) between the pressure apparatus and the doctor element, releasing the contact (K).
