Abstract
The invention relates to a device for accumulating flat material in flexible strip form, the device comprising an accumulator box having a bottom on which the strip accumulates, at least during accumulation stages, between two end walls and between two side walls that extend so as to face edges of the strip. The accumulator device includes at least one of the following means: rollers mounted idle close to the bottom and on which the strip rests during accumulation stages; air-flow means for establishing a flow of air within the box towards the bottom of the accumulator box; vibrator means for vibrating at least one of the side walls; and adjuster means for adjusting spacing between the side walls.
