A gumming device (1) for applying gum (2) to an article (4), whereby the article (4) is fed along a path tangent to a lateral surface (22) of a gumming disk (13) having an inner chamber (16) communicating with a number of radial feed channels (17) terminating at the lateral surface (22) of the gumming disk (13); the gum (2) is fed under pressure to the inner chamber (16) to wet part of the lateral surface (22) of the gumming disk (13) via the feed channels (17); being provided a supply device (24) for supplying gum (2) under pressure to the feed channel (17) having a pump (41) for the gum (2), at least one supply conduit (25, 28) connecting an output of the pump (41) to the feed channel (17), and a valve (29) for closing the supply conduit (25, 28) which is located along the supply conduit (25, 28) and is carried by the gumming disk (13). |
