<p>Dispenser apparatus (33) for a roll of geotextile, which apparatus can be attached to a tractor's (conventional) three-point mounting, this apparatus comprising a long telescopic beam (34), or beam framework, having centrally thereof a three-point mounting (39) by which it can be attached behind a tractor (32) clear of the ground. The beam (34) has end plates (35) between which is a support rod (26) carrying a roll (27) of liner material. The present invention proposes that there be end beams (42) that can be moved in and out by a hydraulic ram (47, 48, 402) mounted between the main beam (41) and the end plates (43) to which the end beams (42) are secured, and that the bottom of each end plate (42) be provided with an inwardly-directed spigot (404, 405, 406) which can be directed into the hole through the liner roll (27) as the rams (47, 48, 402) draw back the end plates (42) to the correct spacing, and so provide the required roll support.</p> |
