| 摘要 |
The invention relates to a method and a device for the treatment of a mineral fibre felt whereby the felt is transported through a transport apparatus while changing the speed thereof. The change of speed is brought about by bringing the felt into contact with at least two elements arranged successively in the transport direction of the felt, the areas of influence of which overlap each other. The apparatus comprises two conveyors (9, 10) arranged opposite each other, between which the felt (3) is transported. Each conveyor comprises at least two shafts (11, 12, and 11', 12', respectively), which are provided with a number of means (16) to be brought into contact with the upper and the lower surface, respectively, of the felt. |
