Abstract

An envelope sealing and feeding device has upper and lower interfitting parts defining a reservoir for a liquid to be used in the sealing operation and a substantially horizontal slot through which an envelope to be sealed can be fed. These parts co-operate with a wetter assembly which includes a wetter blade extending across the slot and a tubular structure containing wicking material and extending substantially vertically downwardly through the upper part and into the liquid reservoir. With this arrangement, replacement of the wetter assembly is made easier. Assembly and dis-assembly of the relevant parts of the machine in order to obtain access to the interior of the liquid reservoir can be done without difficulty. The upper and lower parts can be joined together readily merely by using two bolts or screws, and once joined the wetter assembly can be added easily due to the simple structure, which allows easy preparation of the sub-assembly and then straightforward insertion of a tubular structure thereof in a slot in the upper part. In addition, attachment of the envelope sealer-feeder device onto a postage meter is made particularly easy by the use of a bracket.
