<p>APPARATUS FOR SUPPLYING WRAPPING ELEMENTS TO PACKAGING MACHINES The invention relates to apparatus for supplying wrapping elements (2, 57) comprising elongate portions of card (2) having a series of zones (6, 7, 8, 9), separated by transverse creases (a, b), and flaps (10) defined by creases (c) disposed longitudinally to the card (2). The apparatus comprises first means (14) and second means (50) for continuously transfering the pieces of card (2) which are orientated transversely to the path of the first means and longitudinally with respect to the path of the second means. The apparatus also comprises folding elements (42, 43, 46, 47, 55, 56) located along the paths of the two transfer means (14, 50) arranged to fold the zones (6, 7, 8, 9) and flaps (10) about the creases defining them out of a planar condition and subsequently to fold them back to cause them to return to the original coplanar condition. The pre-creased blanks so formed can be readily wrapped by conventional wrapping machines round soft articles (68) e.g. tablets of soap, reducing the possibility of damage arising during folding.</p> |
