Abstract
In a method for feeding out the primary web of a mineral wool web by means of a pendulum conveyor and to an arrangement of such a pendulum conveyor, an output is fed as close to the receiving conveyor as possible for the primary web to be rapidly fixed onto the underlying web. The conducting rollers at the output end, which rotate in the output direction, have a disturbing effect on such a close output. The front conducting roller in the direction of motion rotates in a direction having a lifting effect on the underlying web, which is negative, whereas the rear conducting roller rotates in a direction pressing down the web being fed out, which is advantageous for the output. Both conveyors of the pendulum conveyor are made vertically movable with regard to each other, the front conducting roller being situated higher and the rear conducting roller lower during the pendulum swing. The reversing mainly takes place in the end position of the pendulum swing. The reversing may take place momentarily or gradually during the entire pendulum motion.
