DETAILED DESCRIPTION OF THE EMBODIMENT

[0049] FIG. 1 shows a first embodiment of a device for a coating material with resin and subsequently laying the material saturated with the resin onto a surface. The material may be applied onto a surface of a structure such as a roof, floor of a deck, or a subsurface of a structure. The device includes a frame 10 and wheels 11 so that the device is moveable along the surface for applying the coated material. A handle 12 (see also FIG. 3) is attached to the frame 10 (and may be moveable from a stowed position to an operative position). A user may grasp the handle 12 to push and/or pull the device and steer the device.

[0050] Pointers 13 may be positioned adjacent opposite sides of the frame 10. The pointers 13 may provide a visual indicator that helps the user steer the device to facilitate the laying of saturated material and to help overlay edges of immediately adjacent rows of laid material.

[0051] The frame 10 supports a resin vessel 14 that may contain a liquid resin. In addition, the frame 10 supports a material roller 15 (in general material holder) onto which material 16 to be saturated with resin is rolled. In FIGS. 1 and 2, a free end 17 of the material 16 is applied on the ground. Adjustable conical centering cones 39 may center a roller core 40 of the material roller 15, even if different material rollers with different roller cores 40 are used (see FIGS. 3 and 4). In order to saturate the material 16 with resin, it is moved through the vessel 14 filled with liquid resin. The material exits the vessel via slot 38 (see FIG. 8).

[0052] A tension adjustment mechanism 18 (see FIG. 3) comprises (a pair of pivotally) moveable members 19 which may come in pressed contact with the material on the material roll 15 (see also FIG. 7). The moveable members 19 may have an elongated plate-shape. The moveable members 19 can be moved by actuating members 20 so that they can be pressed against the roller 15, wherein such pressing force can be regulated by the actuating members 20. The actuating members 20 can be arrested in different positions via arresting means 21 which can be arrested in corresponding arresting means at the frame and/or the handle (not shown in the figures). The arresting means 21 may comprise on or more recess(es) and/or one or more projection(s).

[0053] In particular FIG. 4 shows a plurality of side wheels 41. In general, one or more (e.g. at least two or at least three or at least four) side wheels 41 may be provided on (only) one side of the device or on both sides. These side wheels allow placing the device on its side so that it can be easier to place and/or carry, e.g. in a (cargo) elevator, if necessary.

[0054] FIGS. 5, 8 and 9 show details of a first 23 and second 24 rollers which are arranged at the bottom of the vessel 14 and which guide the material 16 onto the surface to be coated with the material 16.

[0055] A distance between the rollers and a width of the slot 38 can be regulated by a distance and/or slot adjusting mechanism 22. In order to adjust a distance between the rollers 23, 24, the first roller 23 can be pivoted (swivelled) around a rotation axis 25 (see FIG. 5). In order to pivot the first roller 23, a handle 26 (see for example FIG. 3) being connected with a cable 27 (see FIG. 5) is operated. Thereby, an end portion 28 of a supporting member 29, supporting the first roller 23 can be moved in the direction of an arrow 30. This movement may be assisted by one or more spring members (not shown in the figures). Via handle 26 a slot between the rollers 23, 24 may be adjusted.

[0056] Furthermore, FIG. 5 shows a closing mechanism 31, for closing a distance between the rolls 23 and 24. Precisely, the closing mechanism 31 comprises a screw 32 via which the supporting member 29 can be rotated so that the first roller 23 approaches the second roller 24.

[0057] As seen in FIG. 8, each of the first and second rollers 23 and 24 are in contact with a first vane 33 and a second vane 34, respectively. First vane 33 and second vane 34 function as guide members for guiding the material 16 in the direction of the rolls 23 and 24. Moreover, first vane 33 and second vane 34 seal the rollers 23, 24 with respect to the vessel 14. Moreover, a stopping member 35 is provided on either end portion of the rollers 23, 24 and is located partially between the rollers 23, 24 in order to stop flow of resin in a sideward direction.

[0058] A third 36 and fourth 37 (upper) roller are arranged between the material roller 15 (see FIG. 6) and the vessel 14. These rollers 36, 37 may further reduce wrinkling of the material 16. These rollers further enhance the process of applying saturated material. In particular, the risk of movement (sailing) of the fabric (when working under windy conditions) is reduced (to a great extent).
