SHEETS, WEBS, CABLES ## Abstract The invention relates to a wrapping device (300) for wrapping a band around a wound up roll (5″), characterised in:—a storage (301) for said band (303) to be wrapped around said wound up roll (5″),—a first conveyor (330) positionable adjacent said wound roll (5″), for conveying said band (303) to said roll (5″),—said first conveyor (330) comprising a cylindrical drum configured for rotation about an axis (W),—said drum (330) having a surface configured for receiving and transferring said band (303) to said wound up roll (5″) by a vacuum applied to said band (303) via apertures (331) formed in said surface. ## Claims ### Claim 1 A wrapping device for wrapping a band around a roll formed by winding up a length of a web, or interleaved sections of a length of a web, a storage for said band to be wrapped around said formed roll, a first conveyor positionable adjacent said formed roll, for conveying said band to said formed roll, said first conveyor comprising a cylindrical drum configured for rotation about an axis (W), said drum having a surface configured for receiving and transferring said band to said formed roll by a vacuum applied to said band via apertures formed in said surface, characterised in: a pivot frame pivotally connected to a first conveyor frame including said cylindrical drum, and an actuator configured for turning said pivot frame between an active and an inactive position relative to said first conveyor frame, said pivot frame including a roller and elastic belts acting to guide said band being transferred to said formed roll when said pivot frame is in said active position. ### Claim 2 (depends on 1) The device according to claim 1, said drum being configured for progressively releasing said vacuum applied to said band as said band is transferred to said formed roll on rotating said drum. ### Claim 3 (depends on 1) The device according to claim 1, said first conveyor including a core surrounded by a tubular casing defining said drum, a drive for rotating said tubular casing relative to said core, only some of said apertures applying said vacuum at a given time, said application of said vacuum being controlled by rotation of said tubular casing relative to said core. ### Claim 4 (depends on 1) The device according to claim 1, including a second conveyor for conveying said band from said storage to said first conveyor. ### Claim 5 (depends on 4) The device according to the claim 4, said second conveyor including a conduit connected to a source of vacuum, a looped moving belt extending along said conduit having apertures communicating with said conduit. ### Claim 6 (depends on 1) The device according to claim 1, said roller being located on a side of said roll opposite said drum in said active position. ### Claim 7 A roll making apparatus including a roll wrapping device, said apparatus comprising a frame with: a feed conveyor for advancing a length of a web, or interleaved sections of a length of a web, to be wound-up as a roll, a subsection with: a first spindle support mounted to rotate and carrying a plurality of parallel elongated spindles, each spindle mounted for rotation about a respective axis relative to said first spindle support, for winding up thereon said length of a web, or interleaved sections of a length of a web, to form said roll said rotation of said first spindle support and of said spindles being about a respective axis (W) perpendicular to, or essentially perpendicular to, said advancing, said spindles being movable between a retracted position, with a respective distal end thereof closer to said first spindle support, and an extended position, each spindle carrying said formed roll being positionable by said rotation of said spindle support in a wrapping position located next to said wrapping device, characterised in said wrapping device including: a storage for a band to be wrapped around said formed, a first conveyor positioned adjacent said formed roll, for conveying said band to said roll, said first conveyor comprising a cylindrical drum configured for rotation about an axis parallel with said axis (W) of rotation of said spindle carrying said formed roll, said drum having a surface configured for receiving and transferring said band to said formed roll by a vacuum applied to said band via apertures formed in said surface. ### Claim 8 (depends on 7) The apparatus of claim 7, said drum and said spindle carrying said formed roll being configured for rotation in opposite directions, for said transferring of said band. ### Claim 9 (depends on 7) The apparatus of claim 7, said drum being configured for progressively releasing said vacuum applied to said band as said band is transferred to said roll on said rotating of said drum. ### Claim 10 (depends on 7) The apparatus according to claim 7, said first conveyor including a core surrounded by a tubular casing defining said drum, a drive for rotating said tubular casing relative to said core, only some of said apertures applying said vacuum at a given time, said application of said vacuum being controlled by said rotation of said tubular casing relative to said core. ### Claim 11 (depends on 7) The apparatus according to claim 7, including a second conveyor for conveying said band from said storage to said first conveyor. ###

15 (depends on 7) The apparatus according to claim 7, said wrapping device including a pivot frame pivotally connected to a first conveyor frame including said first conveyor frame an actuator configured for turning said pivot frame between an active and an inactive position relative to said first conveyor frame, said pivot frame including a roller and elastic belts acting to guide said band being transferred to said formed roll when said pivot frame is in said active position, said roller preferably located on a side of said roll opposite said drum in said active position. ### Claim 16 A roll making apparatus including a roll wrapping device, said apparatus comprising a frame with: a feed conveyor for advancing a length of a web, or interleaved sections of a length of a web, to be wound-up as a roll, a spindle support carrying an elongated spindle mounted for rotation about an axis (W) perpendicular to, or essentially perpendicular to, said advancing, for winding up thereon
