Abstract
The invention relates to a roll making apparatus comprising spindles optionally having apertures for pressurized air and/or for applying a vacuum, the spindles being movable between a retracted position and an extended position, a roll engaging face configured to engage a roll carried by a spindle, upon the spindle carrying said roll moving to said retracted position, to move the roll relative to the spindle.
Claims32
A roll making apparatus comprising:
- a frame comprising a feed conveyor for advancing a length of a web to be wound-up as a roll;
- a subsection comprising a first spindle support mounted to rotate and carry a plurality of parallel elongated spindles, each spindle mounted to rotate relative to said first spindle support, for winding up thereon said length of said web, said rotation of said first spindle support and of said spindles being about a respective axis perpendicular to said advancing length of the web, said spindles comprising a respective distal end and being movable between a retracted position, wherein said respective distal end is closer to said first spindle support, and an extended position;
- a face disposed on said first spindle support, the face configured to engage said roll carried by a spindle of said plurality of parallel elongated spindles, upon said spindle carrying said roll moving to said retracted position, to move said roll relative to said spindle;
- and
- a conveying device for conveying rolls discharged from said spindle upon said spindles moving to said retracted position, said spindles having apertures along a length thereof for one of applying pressurized air, applying a vacuum, and interchangeably applying pressurized air and applying the vacuum.
