Method and device for centring labels during application onto small surfaces

摘要

Method and device for centring labels (2) while applying them to small surfaces includes picking up a label (2) from a feeding line (6) by vacuum operated picking up means (13) connected to a tubular body (10) which communicates with suction means. These picking up means are subsequently introduced into a sized-apertured member (17) coaxial therewith and connected to a sleeve (14) which slides on the tubular body (10) thus limiting, in a transitory step, the above mentioned depression in order to centre the label (2) with respect to the picking up means (13). The sized-apertured member (17) is set centred axially on a container (3) by axial movement of the sleeve (14). Subsequently, the picking up means (13) are moved with respect to the sleeve (14), so as to apply the label (2) onto the container (3). <IMAGE>
