Abstract
Stretch wrapping apparatus that uses two rollers 17,18 rotating at different speeds to stretch a web or wrapping material has problems of slippage when applied to wrapping grass. These are ameliorated by forming the roller surfaces with projections 32, e.g. by applying a mesh or (better) forming axial corrugations. The surfaces are preferably of metal, particularly aluminum.
