Abstract
Upon filling cans with fiber band, the movable bottom of the cans, as the filling process proceeds, moves downwardly from an initial upper to a lower final position. As this happens, between two elements, one inside, one outside the circumferential shell of the can, a force field is built up in such a way that the element inside the can supports the can bottom and because of the force field, this bottom is held at the same elevation as the element outside of the can. Further, the desired operating height of the can bottom can be correspondingly held. For the lowering of the can bottom, one of the two elements between which the force field exists, is moved relative to the other in the direction of the lower final positioning of the can bottom and the remaining element follows after, because of said force field, until both elements again stand across from one another at the same height. Along with this, for the support of the can bottom a force, directed at right angles to the circumferential shell, is produced to form a braking force directed contrary to the weight of the loaded can bottom.
