Apparatus for closing a folded package without the use of gluing means and related method for closing a folded package

Abstract

Apparatus (80) for closing a folded package (4) without the use of gluing means, comprising retaining means (84) for the package (4) in a folded configuration, the package (4) comprising at least one rear flap (8) and at least one front flap (12), overlapped on the rear flap (8), on the opposite side to a containment volume (16) delimited by the package (4), at least one pusher (192) having an operating stroke adapted to move a closing tab (44) of the front flap (12), hinged along a closing line (52), towards the rear flap (8) so as to interlock said closing tab (44) in a notch (40) on the rear flap ( 8 ). The pusher (192) comprises a slider (194) and a head (196), the slider (194) being operated according to an at least partially straight operating stroke along a longitudinal extension axis (L-L), the head (196) being hinged with respect to the slider (194) by means of a pin (198), so as to be rotatable, with respect to the slider (194), around a rotation axis (Z-Z) perpendicular to said longitudinal extension axis (L-L). Advantageously, the pusher (192) comprises a return means (204) comprising a connecting rod (212) having a first end (205), hinged to the head (196) itself, and a second end (206) hinged to a fixed wall (208) of the retaining means (84).
