A C-shaped innerframe is preformed and then applied to a preformed cigarette bundle as part of a cigarette packing operation. The preformed innerframe first contacts the bundle with the back of the C in contact with the front surface of the bundle, and with the arms of the C adjacent the sides of the bundle and projecting rearwarly behind the rear surface of the bundle. Thereafter, the arms of the C are brought in against the side and rear surfaces of the bundle to complete application of the innerframe to the bundle.

1. Apparatus for wrapping a cigarette pack innerframe around a previously assembled bundle of cigarettes, said bundle having a front surface, a rear surface substantially parallel to and spaced from said front surface, and a pair of side surfaces which are substantially parallel to and spaced from one another and which interconnect side margins of said front and rear surfaces, said innerframe having a front wall which is to at least partly cover said front surface, a pair of side walls, each of which is to at least partly cover a respective associated one of said side surfaces and each of which is connected to a respective one of opposite side margins of said front wall, and a pair of rear flaps each of which is to partly cover said rear surface and each of which is connected to a respective one of said side walls along a side margin of said side wall which is spaced from the side margin of the front wall to which that side wall is connected, said innerframe being prebent separate from said bundle at all four of said side margins of said innerframe so that the cross section of said innerframe perpendicular to said innerframe side margins is approximately C-shaped, said apparatus comprising: means for supporting said bundle so that the front and side surfaces of said bundle are exposed; means for holding said prebent innerframe open so that the edges of said rear flaps which are parallel to but spaced from said side margins are spaced apart by a distance greater than the spacing between said side surfaces; means for placing said prebent but held open innerframe on said bundle so that each of said rear flaps can pass outside of a respective one of said side surfaces in order to project behind said rear surface, and so that said front wall rests on said front surface; means for moving said bundle and said innerframe together in a predetermined direction along a longitudinal axis which is substantially parallel to said side margins of said front and rear surfaces; and means for guiding said rear flaps forward one another and into contact with said rear surface as said bundle and said innerframe move along said longitudinal axis to at least partly cover said rear surface inserted. 2. The apparatus defined in claim 1 wherein said means for guiding comprises: a pair of edges which are substantially co-planar with said rear surface and which are synclinal in said predetermined direction, each of said edges having an upstream portion where said edges are most remote from one another and a downstream portion where said edges are closest to one another, said upstream portions being far enough apart to allow said bundle and said innerframe to pass between said upstream portions without substantially contacting said upstream portions, and both of said downstream portions being adjacent said rear surface so that as said bundle and said innerframe move along said longitudinal axis, said edges engage said rear flaps and push them toward one another and against said rear surface. 3. The apparatus defined in claim 2 wherein said means for supporting said bundle comprises: a bed for supporting a portion of said rear surface. 4. The apparatus defined in claim 3 wherein each of said edges is an edge of a respective associated one of a pair of slots formed in said bed. 5. The apparatus defined in claim 4 wherein each of said edges is the edge of the side of the associated slot which is remote from the other of said slots. 6. The method of wrapping a cigarette pack innerframe around a previously assembled bundle of cigarettes, said bundle having a front surface, a rear surface substantially parallel to sand spaced from said front surface, and a pair of side surfaces parallel to and spaced from one another and which interconnect side margins of said front and rear surfaces, said innerframe having a front wall which is to at least partly cover said front surface, a pair of side walls each of which is to at least partly cover a respective associated one of said side surfaces and each of which is connected to a respective one of opposite side margins of said front wall, and a pair of rear flaps each of which is to partly cover said rear surface and each of which is connected to a respective one of said side walls along a side margin of said side wall which is spaced from the side margin of the front wall to which that side wall is connected, said innerframe being prebent separate from said bundle at all four of said side margins of said innerframe so that the cross section of said innerframe perpendicular to said innerframe side margins is approximately C-shaped, said method comprising the steps of: supporting said bundle so that the front and side surfaces of said bundle are exposed; holding said prebent innerframe open so that the edges of said rear flaps which are parallel to but spaced from said side margins are spaced apart by a distance greater than the spacing between said side surfaces; placing said prebent but held open innerframe on said bundle so that each of said rear flanges can pass outside of a respective one of said side surfaces in order to project behind said rear surface, and so that said front wall rests on said front surface; moving said bundle and said innerframe together in a predetermined direction along a longitudinal axis which is substantially parallel to said side margins of said front and rear surfaces; and guiding said rear flaps toward one another and into contact with said rear surface as said bundle and said innerframe move along said longitudinal axis to at least partly cover said rear surface. 7. The method defined in claim 6 wherein said guiding step comprises the step of: providing a pair of edges which are substantially co-planar with said rear surface and which are synclinal in said predetermined direction, each of said edges having an upstream portion where said edges are most remote from one another and a downstream portion where said edges are closest to one another, said upstream portions being far enough apart to allow said bundle and said innerframe to pass between said upstream portions without substantially contacting said upstream portions, and both of said downstream portions being in contact with said rear surface so that as said bundle and said innerframe move along said longitudinal axis, said edges engage said rear flaps and push them toward one another and against said rear surface. 8. Apparatus for wrapping a bundle of cigarettes in a C-shaped innerframe comprising: means for preforming an innerframe into an approximately C-shape, a front wall of the innerframe being the back of the C, and each of the arms of the C including a respective one of two side walls and a respective one of two rear flaps of the innerframe, said preformed innerframe being bent where each of said side walls joins said front wall and where each of said rear flaps joins the associated side wall; means for separately preforming a bundle of cigarettes having a front surface, a rear surface, and two side surfaces; means for holding said preformed innerframe open so that the edges of said rear flaps which are remote from the side walls are spaced apart by a distance greater than the spacing between said side surfaces; means for applying said preformed but held open innerframe to said bundle so that said front wall of said innerframe is in contact with said front surface and so that each of said arms of the C extends adjacent a respective associated one of said side surfaces and projects rearwardly of said rear surface; and means for pressing each of said side walls in against the associated one of said side surfaces and both of said rear flaps in against said rear surface to at least partly cover said rear surface. 9. The apparatus defined in claim 8 wherein said means for pressing comprises: a pair of opposing edges disposed substantially in a plane defined by said rear surface; and means for producing relative motion between said bundle and said innerframe, on the one hand, and said edges on the other hand, said relative motion being in a predetermined direction along a substantially longitudinal axis in said plane, said longitudinal axis being substantially parallel to said front, rear, and side surfaces, said edges being disposed substantially symmetrically on respective opposite sides of said longitudinal axis from upstream portions where said edges are relatively far apart to downstream portions where said edges gradually converge toward one another, the spacing between said upstream portions being greater than the spacing of the arms of the C and the smallest spacing between said downstream portions being not greatly more than the spacing between said rear flaps when said innerframe is fully wrapped around said bundle so that as said bundle and said innerframe move relative to said edges, said edges move said side walls in against said side surfaces and also move said rear flaps in against said rear surface. 10. The method of wrapping a bundle of cigarettes in a C-shaped innerframe comprising the steps of: preforming an innerframe into an approximately C-shape, a front wall of the innerframe being the back of the C, and each of the arms of the C including a respective one of two rear flaps of the innerframe, said preformed innerframe being bent where each of said side walls joins said front wall and where each of said rear flaps joins the associated side wall; separately performing a bundle of cigarettes having a front surface, a rear surface, and two side surfaces; holding said preformed innerframe open so that the edges of said rear flaps which are remote from the side walls are spaced apart by a distance greater than the spacing between said side surfaces; applying said preformed but held open innerframe to said bundle so that said front wall of said innerframe is in contact with said front surface and so that each of said arms of the C extends adjacent a respective associated one of said side surfaces and projects rearwardly of said rear surface; and pressing each of said side walls in against the associated one of said side surfaces and both of said rear flaps in against said rear surface to at least partly cover said rear surface. 11. The method defined in claim 10 wherein said pressing step comprises the steps of: providing a pair of opposing edges disposed substantially in a plane defined by said rear surface; and moving said bundle and said innerframe relative to said edges in a predetermined direction along a substantially longitudinal axis in said plane, said longitudinal axis being substantially parallel to said front, rear, and side surfaces, said edges being disposed substantially symmetrically on respective opposite sides of said longitudinal axis and extending along said axis from upstream portions where said edges are relatively far apart to downstream portions where said edges gradually converge toward one another, the spacing between said upstream portions being greater than the spacing of the arms of the C, and the smallest spacing between said downstream portions being not greatly more than the spacing between said rear flaps when said innerframe is fully wrapped around said bundle so that as said bundle and said innerframe move relative to said edges, said edges move said side walls in against said side surfaces and also move said rear flaps in against said rear surface.
