Abstract
A finishing machine for the laying of the asphalt surface having a conveyer, and a hopper for the storage and the distribution of material. The conveyer, that moves material from the hopper to the auger, has a couple of chains connected with one another by transversal splines that are suitable for the transport of the material. The material crawls on a plurality of fixed plates secured to the frame of the machine, and the chains run on the plates. The last plate, which supports the passing material, is floating in comparison with the fixed plate which precedes it. The last plate is on a weighing device, and the device is connected with a control power unit. The control power unit detects a signal relevant to the reading of the weight of the material. The signals are detected at time intervals, depending on the angular speed of the hopper, and allows weighings to take place after all the weighed material has been unloaded from the weighing plate.
