Abstract
A gummer for a filter attachment machine comprises two rollers (10, 12), one of which is arranged to contact the web and the other of which is pressed against the first roller to limit the quantity of gum which is transmitted to the web from a pool of gum formed in the nip between the rollers. Gum is fed continuously into the pool at a position between the ends of the rollers at a rate in excess of the rate at which gum is applied to the web, from which position the gum flows towards the ends of the rollers. Means (15, 16, 50) are provided for collecting excess gum at the ends of the rollers and for returning it to a source (19) of the gum.
