| 摘要 |
The invention relates to a melting device for melting solid hot-melt adhesive, preferably in the form of granules, in particular for edge gluing machines, with a heatable melt wall equipped with passage openings, a cylindrical pressure chamber arranged upstream of the melt wall in the passage direction, a pneumatically actuated pressure piston movable in the pressure chamber towards the melt wall, a feed opening formed in the pressure chamber wall and a supply tank, connected to the feed opening, for the solid hot-melt adhesive. To further develop the melting device such that, with reduced space requirement, the technical outlay for controlling the granule feed to the pressure chamber is reduced and the tendency of the granules to adhere and to form bridges is reduced, it is provided to design the pressure piston (8) as a working cylinder in the interior space of which an actuating piston (13) is guided, which actuating piston (13) is connected to a piston rod (12) which projects through a bore in the end plate (11), facing away from the melt wall, of the working cylinder and is fastened to the device at its end (14). <IMAGE> |
