| 摘要 |
The invention concerns a device for manufacturing plane slabs consisting of a known device, which produces a continuous band of cement, filling materials and reinforcing fibres (8), supported on a base sheet (2) of the desired length and thickness for the slab, and lays it on a corresponding conveyor band (15) on supporting plates (16), which are driven end-to-end on a second band (15) passing under. The invention is characterised in that the continuous band (7) is cut by an appropriate cutting device (13) on the supporting plate (16) at a distance preferably of 5 - 15 cm. from the end of the supporting plate (16), after which the forward movement of the supporting plates (16) is briefly accelerated such that they slide off the front end of the continuous band (15) preferably at a distance twice the preferred distance of 5 - 15 cm, and finally resume the conveying speed of the continuous band (15) until the slab thus laid down is cut again. The invention also concerns a method for manufacturing plane slabs (14) with improved surface quality. |
