Abstract
An apparatus (20) for folding a sheet of foil (11) includes a feeder (23) and a folding means (24). The feeder (23) can feed a sheet of foil to the folding means (24). The folding means (24) includes a first surface (27) and a second surface (28) which can be arranged to bear against first and second opposing faces respectively of a portion (31) of the sheet of foil (11) at or near to the leading edge (11′) of the sheet of foil. One or both of the first and second surfaces (27,28) can be rotated about a foldable axis between the first and second opposing faces to create a first fold along the foldable axis.
