Dispositivo di lavorazione per tappi e/o componenti di tappi

A processing device (1 ) for caps and/or components of said caps is provided, comprising a first processing portion (2) having a first processing direction (2a) and including at least one first processing member (20); a second processing portion (3) spaced apart from said first processing portion (2), having a second processing direction (3a), and including at least one second processing member (30); stiff coupling means (4) configured to mechanically, firmly connect the processing portions (2, 3) in such a way that the processing directions (2a, 3a) are always aligned with each other; a positioning member (5) configured to move a cap so that it is placed on and/or removed from the first processing member (20); wherein the processing members (20, 30) are mutually mobile between a spaced- apart position, wherein the processing members (20, 30) are at a first predefined distance, and a close-together position, wherein the processing members (20, 30) are at a second predefined distance that is less than the first predefined distance and cooperate with each other so as to process the cap; wherein the device (1 ) can be moved along an assembly path (6a) at least from a first point (A) to a second point (B) spaced apart from the first point (A), the positioning member (5) places the cap on the first processing member (20) in the first point (A) and in the second point (B), and wherein the processing members (20, 30) assume the close-together position when moving between the first point (A) and the second point (B), and are in the spaced-apart position when the device (1) is in the first point (A) and when it is in the second point (B).
