Abstract (en)
[origin: WO8803121A1] A process for feeding out a primary web of mineral wool onto a receiving conveyor. For this purpose, a pendulum conveyor has been used. In order to achieve good quality and the desired capacity the primary web must be thin and output rate high, which causes problems in fixing the primary web into the already fed out web and in looping the edges of the fed out web. According to the invention, these problems have been solved by making the trajectory and rate of motion of the output end (10) of the receiving conveyor (2) to comprise a central portion (B1) with a constant speed, which equals or is close to the output rate of the primary web, and an outmost portion (B2) having a retarding or accelerating speed, respectively. By this means the output end may move close to the receiving conveyor and be rapidly fixed into the bed while the pendulum allows appropriate space in the extreme positions for the edge loop, which also is rapidly fixed into the bed and forms an even edge. The invention relates also to a device for carrying out the process.
