Abstract
A package strapping machine for strapping a package to a pallet, which pallet is usually constructed from lumber and is of standard shape or configuration. The pallet comprises generally a supporting platform for the package with longitudinally parallel extending stringers secured to the underside of the supporting platform. The strapping machine is provided with a strapping station where the package is tied to the pallet and is so constructed that a strap is carried beneath the stringers and through a strap ring including an arch around the package if the pallet is facing in one direction, because a pallet position sensing means, such as a ray of light which is provided at one side of the pallet, cannot pass through the solid stringers to a photo-sensitive device located at the other side of the pallet. However, if the pallet is turned 90.degree. so that the voids between the stringers which extend completely through the pallet structure are positioned 90.degree. from aforementioned position, the ray of light at one end then passes through the void and impinges upon a light-sensitive device at the other end of the pallet. The strap then will not be carried underneath the stringers…
