Abstract

Folding apparatus (201) for folding ends of wrapping material (202) extending beyond opposite lateral sides of a pulp bale (203). The folding apparatus comprises first displacement means (204) configured to displace the pulp bale in a first longitudinal direction (Rl) to a first folding area (205), the lateral sides (203c) of the pulp bale facing perpendicularly relative the first longitudinal direction, and at least one fixed first folding plate (206a, 206b) arranged at the first folding area at each lateral side of the first folding area. The fixed folding plates are at a distance from each other adapted to a bale width. The folding plates each define a respective folding surface being disposed substantially perpendicularly relative the folding area and being substantially in parallel with the first longitudinal direction. The first displacement means is further configured to displace the pulp bale in a direction (R2) opposite the first longitudinal direction away from the first folding area (205).
