Abstract
In the feeding of sheet material to a machine such as a tire building former a sheet is first placed on a table and one edge of the sheet is aligned with a first datum line, preferably by tilting the table and supplying floatation air under the sheet. The sheet is then picked up and moved transversely through a predetermined distance by a gripping device to align one edge with a second datum line so as to enable the sheet to be fed in appropriate alignment to a machine.
