Claim 10

A baled article comprising a bale of crop material of generally cylindrical form having a circumference and having a predetermined length and opposite end faces having outer peripheral portions, baling material confining said bale and comprising a strip of material having a length and a longitudinal direction extending along the length of the strip, said strip having a width greater than the predetermined length of said bale, said strip of material having opposite longitudinal edge portions which are elastic in the longitudinal direction, said strip of material being wrapped around said bale with the opposite longitudinal edge portions thereof extending generally radially inwardly of the bale to cover at least the outer peripheral portions of each of said end faces, the baling material comprising foil material, said edge portions having first perforations formed therein, said foil material having a central portion of foil material between said edge portions, said central portion having second perforations formed therein, said second perforations being more widely spaced than said first perforations.

Claim 11

A baled article comprising a bale of crop material of generally cylindrical form having a circumference and having a predetermined length and opposite end faces having outer peripheral portions, baling material confining said bale and comprising a strip of material having a length and a longitudinal direction extending along the length of the strip, said strip having a width greater than the predetermined length of said bale, said strip of material having opposite longitudinal edge portions which are elastic in the longitudinal direction, said strip of material being wrapped around said bale with the opposite longitudinal edge portions thereof extending generally radially inwardly of the bale to cover at least the outer peripheral portions of each of said end faces, the baling material comprising foil material, said edge portions having first perforations formed therein, said foil material having a central portion of foil material between said edge portions, said central portion having second perforations formed therein, said second perforations being more widely spaced than said first perforations.

Claim 12

A baled article as defined in claim 7 wherein each of said perforations comprises elongated perforations extending transversely to said longitudinal edge portions.

Claim 13

A baling device comprising a plurality of feed belts defining a generally cylindrical wrapping chamber, means for feeding a strip of crop material into said chamber to engage said feed belts, said feed belts being arranged to form said strip of crop into a generally cylindrical bale having a circumference and being of predetermined length and having opposite end faces including outer peripheral portions, a source of baling material comprising an elongated strip of baling material having a length and a longitudinal direction extending along the length of the strip, said strip having a width greater than said predetermined length of the bale, said strip having opposite longitudinal edge portions which are elastic in the longitudinal direction and each of which includes an elastic element extending in the longitudinal direction of the strip, and supply means for supplying said strip to said feed belts so that the strip is wrapped around said bale with the opposite longitudinal edges of the strip extending generally radially inwardly of the bale to cover at least the outer peripheral portions of each of the end faces of the bale.

Claim 14

A baling device comprising a plurality of feed belts defining a generally cylindrical wrapping chamber, means for feeding a strip of crop material into said chamber to engage said feed belts, said feed belts being arranged to form said strip of crop into a generally cylindrical bale having a circumference and being of predetermined length and having opposite end faces including outer peripheral portions, a source of baling material comprising an elongated strip of baling material having a length and a longitudinal direction extending along the length of the strip, said strip having a width greater than said predetermined length of the bale, said strip having opposite longitudinal edge portions which are elastic in the longitudinal direction and each of which includes an elastic element extending in the longitudinal direction of the strip, and supply means for supplying said strip to said feed belts so that the strip is wrapped around said bale with the opposite longitudinal edges of the strip extending generally radially inwardly of the bale to cover at least the outer peripheral portions of each of the end faces of the bale.
