摘要

Mechanism to correct the advancement errors in packaging machines by printed continuous band envelopes. Understands a photocell (1), provided by the step of some stops (2) placed in one of the edges of the continuous band (3) and detects the error, which through a stage of power governs the heel (4) from an electroiman (5). The position of the heel (4) determines the end of the race of an arm (6) powered by a cam (7) which acts through a rod (8), on a articulation (9) adjustable along an arm (10) ) that determines the advance and reverse of a clamp (11) which continuously displaces the band with the step of a scissor (12) synchronized with the advance. 2 (Machine-translation by Google Translate, not legally binding)
