Abstract:

Disclosed is a support structure mounting groups of rollers with each group having a first pair of rollers spaced one from the other for rotation about parallel axes and a second pair of rollers spaced one from the other for rotation about parallel axes generally normal to the first mentioned parallel axes. The opposed rollers of each pair thereof in each group in part define and lie on opposite sides of the path movement of unstraightened bar stock being fed to a straightening machine. The spacing between the opposed rollers is substantially greater than the diameter of the bar stock passing through the feed mechanism. A motor and chain drive is coupled to the groups of rollers such that a pair of rollers of each group and one other roller in each group are driven thereby to advance the unstraightened bars through the feed mechanism. The rollers carry resilient material about their peripheries whereby the noise level generated by the whipping or flailing action of the unstraightened bars against the rollers of the feed mechanism is substantially reduced.
