Coupling unit and coupling method for coupling a component to a container and apparatus for producing articles correlated thereto

Abstract

A coupling unit for coupling a component for a container includes a coupling equipment. The coupling equipment includes: a frame, a housing constrained to the frame, a gripping device rotatably constrained with respect to the frame and including a retaining element to selectively retain the component, and a coupling device constrained to the gripping device with respect to the frame, the coupling device including a coupling element to constrain a portion of the component to a coupling surface of the container at a coupling position. The gripping device and the coupling device can move along an arc with a curved trajectory to a removal position where the retaining element is oriented to receive at least one component to be retained, and to a coupling position where the retaining element and the coupling element bring an abutment surface of the container and a couplable portion of the component into contact.
