Abstract
Abstract A device for folding a sheet of wrapping material around external surfaces of an article of parallelepipedonal shape is disclosed. The device comprises a revolver provided with wall members defining a plurality of cells, the revolver being so rotatable stepwise that each of the cells comes to rest successively at a first station, a second station, a third station and a fourth station of the device. The cells are constructed so to receive at the first station a sheet of wrapping material and so to receive at the second station an article to be wrapped that such sheet of wrapping material is disposed between the received article and walls of the cell in which that article is received, with lobes of the sheet projecting in a direction parallel to the axis of rotation beyond an end face of the article. The device is provided with folder means disposed at the third station, the folder means comprising a folder member rotatably mounted on carrier means reciprocatably displaceable along guide means to impart such simultaneous rotational and translational motion to the folder member that the latter is moved towards a cell located at the third station when the carrier means is displaced along the guide means in a first direction and the folder member is moved away from the cell when the carrier means is displaced in a direction opposite to the first direction. The arrangement is such that displacement of the carrier means in the first direction causes the folder member to engage one of the projecting lobes and to fold the latter against the end face of an article in a cell at the third station.

Claim 1
Independent Claim
361 words
A device for folding a sheet of wrapping material around external surfaces of an article of parallelepipedonal shape, said device comprising, in combination: a support; article receiving means rotatably mounted on said support to be rotatable about an axis; cell defining means provided by wall members of said article receiving means to define a plurality of cells spaced at angular intervals about said axis and extending in a generally radial direction relative thereto, each cell being adapted to receive one said article; means to rotate said article receiving means stepwise about said axis to cause each said cell to be arrested successively at a first station, a second station, a third station and a fourth station of said device; means to introduce a sheet of wrapping material into one said cell when the latter is located at said first station; means to introduce said article into said cell when the latter is located at said second station, whereby said sheet of wrapping material is disposed between said article and walls of said cell in which said article is received, with lobes of said sheet projecting beyond an end face of said article and in a direction parallel to said axis; carrier means disposed at said third station; guide means co-operating with said carrier means; a folder member rotatably supported on said carrier means; a roller member connected to said folder member to rotate therewith and rollably engaging said guide means; and means to reciprocatably displace said carrier means along said guide means, thereby to impart simultaneous rotational and translational motion to said folder member, whereby the latter is moved towards and along the axial end face of said cell located at said third station when said carrier means is displaced along said guide means in a first direction and said folder member is moved away from said cell when said carrier means is displaced in a direction opposite to said first direction, said displacement of said carrier means in said first direction causing said folder member to engage one of said projecting lobes and to fold the latter against said face of said article in said cell at said third station.
Claim 2
Independent Claim
361 words
A device for folding a sheet of wrapping material around external surfaces of an article of parallelepipedonal shape, said device comprising, in combination: a support; article receiving means rotatably mounted on said support to be rotatable about an axis; cell defining means provided by wall members of said article receiving means to define a plurality of cells spaced at angular intervals about said axis and extending in a generally radial direction relative thereto, each cell being adapted to receive one said article; means to rotate said article receiving means stepwise about said axis to cause each said cell to be arrested successively at a first station, a second station, a third station and a fourth station of said device; means to introduce a sheet of wrapping material into one said cell when the latter is located at said first station; means to introduce said article into said cell when the latter is located at said second station, whereby said sheet of wrapping material is disposed between said article and walls of said cell in which said article is received, with lobes of said sheet projecting beyond an end face of said article and in a direction parallel to said axis; carrier means disposed at said third station; guide means co-operating with said carrier means; a folder member rotatably supported on said carrier means; a roller member connected to said folder member to rotate therewith and rollably engaging said guide means; and means to reciprocatably displace said carrier means along said guide means, thereby to impart simultaneous rotational and translational motion to said folder member, whereby the latter is moved towards and along the axial end face of said cell located at said third station when said carrier means is displaced along said guide means in a first direction and said folder member is moved away from said cell when said carrier means is displaced in a direction opposite to said first direction, said displacement of said carrier means in said first direction causing said folder member to engage one of said projecting lobes and to fold the latter against said face of said article in said cell at said third station.
Claim 3
Dependent Claim
36 words
A device as defined in claim 1, wherein said guide means comprises a racked member and said roller member is provided with teeth disposed around the periphery of said roller member to engage said racked member.
Claim 4
Dependent Claim
98 words
A device as defined in claim 1, wherein said folder member comprises an angle member having two mutually perpendicular arms; whereby when said carrier means is displaced along said guide means in said first direction from one end of its stroke to the other, one of said arms is moved from a first position - in which said one arm is spaced apart from said cell at said third station - to a second position - in which said one arm is located next adjacent said axial end face and extends substantially perpendicularly to said axis of rotation.
Claim 5
Dependent Claim
66 words
A device as defined in claim 1, additionally comprising a stationary further folder member located next adjacent the path of displacement of said cell; whereby on said article receiving means being rotated to displace said cell from said third station to said fourth station, a further said lobe is folded by interaction with said stationary folder member to overlie said axial end face of said article.
Claim 6
Dependent Claim
49 words
A device as defined in claim 1, further comprising at least one further folder member mounted to be reciprocatably displaceable in a direction radial to said axis to fold a respective other said lobe over said end face of said article in said cell located at said third station.
