ABSTRACT:
A roll stand for holding rolls of material such as paper rolls which allows the rolls to be mounted and material fed out. The roll stand includes a roll supporting bar which is raised and lowered by a mechanical system such as an air piston. The roll supporting bar is lowered to allow a roll of material to be mounted, and then raised to allow the roll to turn freely. The roll stand includes a roll retainer, including a bar which swings down against the end of the roll, to keep the roll properly positioned on the roll supporting bar. The roll retainer swings up out of the way while a roll of material is mounted or removed. A rotating mechanism maintains the roll retainer in whatever position it is moved to. The roll stand may also be configured to support a plurality of rolls, each roll lifted into place on its own roll supporting bar. The roll supporting bars are positioned to hold all the rolls with a minimum of floor space.
