The invention concerns an adhesive block of hot-melting material for an adhesive dispenser in which the block advances along a feed passage under the action of pressurised fluid, is melted and is dispensed as a liquid adhesive, the block having one or more flanges formed on its body, the or each flange being shaped and dimensioned to be capable of serving as a piston face for the direct application of pressurised fluid thereto, whereby the block can be advanced along the feed passage in sealing engagement therewith. Processes for forming such a block are described, including a cold forming process. A variety of block-and-flange configuration are disclosed.
