Abstract: The asphalt laying machine comprises a rear body divided into sections with smoothing and compacting units suspended through vibration dampers in the frame. Each unit comprises an intermediate part and a smoothing part interconnected by means of a rear shaft bearing and a front connecting rod connected to an eccentric. By virtue of this interconnection an elliptical movement is transferred to the smoothing part during operation of the machine, and this movement produces a heavy tamping at the front edge, a smoothing and vibrating effect at the intermediate area of the ironing plate, and a succeeding tamping and polishing effect at the rear edge area. The tamping foot of a scraper plate suspended on the intermediate part tamps laid asphalt synchronously in opposition to the tamping plate of the ironing plate by virtue of reaction forces transferred through the intermediate part.

Abstract: The dosage granulator comprises a feed hopper receiving reclaimed asphalt to be granulated. Under the lower opening of the feed hopper, a tearing up device is situated which is controlled by a conveyor type weigher mounted thereunder. The tearing up device comprises tearing rollers with knives, gratings, and a plurality of pressure arms reciprocating through the spaces of the gratings to press the material downwards. The tearing rollers rotate to drive the material towards the gratings, where it is cut by the knives in co-operation with said gratings. The dosage granulator may comprise a reciprocating stirrer situated between the tearing rollers. Reclaimed asphalt of a size of up to 30 cm may thereby be cut into granules of 5 cm. The amount of granulated material is adjusted by means of the conveyor tape weigher.

Abstract: An apparatus for applying hot thermoplastic stripe material to a solid surface. The apparatus comprises a pipe circuit including various means for storing and circulating stripe material, an applying device for said material, as well as an electronic control unit controlling the applying device. The applying device comprises a plurality of adjoining controllable gates. Each gate opening is of a width, i.e. the dimension perpendicular to the paper of FIG. 1, corresponding to a width module in the multi-stripe complex to be applied, whereas the height of the gate opening corresponds to the thickness of the applied material. The total width of the gates corresponds at least to the total width of the multi-stripe complex to be applied. Fluid-operated actuating means are present on the applying device, which serve to open and close the gates quickly. In this manner a possibility of a simultaneous applying of several marking stripes in a multi-stripe complex is obtained.
