ABSTRACT OF THE DISCLOSURE A roller assembly having longitudinal ribs which snap fit into shelf members of a support frame. In one embod- iment the shelf members have upright T-shaped end members with lateral extending feet that engage the ribs. In another embodiment the shelf members have longitudinal feet that engage the ribs. Preferably, the edge forming the underside of the roller assembly are supported by base portions of the shelf member. The roller assembly can be produced by a series of bending, stamping and roll-forming operations including advancing a generally continuous metal web through a series of processing stations, including: blanking side wall openings in the web without completely severing the material from the web, simul- taneously stamping roller-receiving openings in the web, form- ing longitudinal ribs and generally U-shaped edges with up- turned flanges, bending the material blanked in the web to form arcuate shaft sections, placing the roller on the web and roll- forming the web to form a channel-shaped rail frame while simultaneously inserting the arcuate shaft sections into the hub of the roller.
