A bottom feeding mechanism, comprised of a plurality of caged balls and an endless belt in frictional driving contact therewith, is provided with an edge gage for uniformly positioning work pieces, especially flexible sheet material such as fabric, fed onto the balls. In addition to adjustably determining a selected marginal position and/or a line of feeding, for instance as required for hemming and/or stitching machines, the device is adaptable for turning over successive work pieces and aligning them in uniform manner.
