Abstract
A moveable skid is provided to sense the height of a pallet fed to a raisable and lowerable platform. The skid determines the height of the pallet before it is fed to a raisable and lowerable platform of a sheet stacking apparatus so that the position of the pallet below an intermediate stacking platform can be determined during the pallet change. This prevents adverse effects by nondetrimental projections above the surface of the pallet and prevents an excessive drop of the intermediate stack as it is transferred to the pallet.
