Roll changing apparatus
摘要:
An apparatus exchanges a roll remnant and a full roll. The apparatus comprises a dump cradle and a roll-transfer surface. The roll-transfer surface includes an extension element capable of transitioning between a retracted position and an extended position. The apparatus also includes a roll-delivery element capable of providing a fresh roll of material to the dump cradle and of removing a remnant of a previous roll from the apparatus.
