A wrapping device for a machine for winding-up a web material, and a machine for winding-up a web material including the wrapping device

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.
