Machine for processing billet or bar stock

Claim 2

A machine for processing billet or bar stock, comprising; a machine head, a roller mechanism including a plurality of driven, horizontally disposed table rollers for driving said stock into and out of engagement with the head, and co-operating sets of rolls on each side of the head for laterally gripping the stock, at least one roll in each set and a plurality of other rolls in the roller mechanism aligned therewith having surfaces inclined to the horizontal plane to provide edge support for the stock on its leading and trailing ends in dependence on the stock shape, and control means for controlling both the rate of drive of the stock along the roller mechanism and the operation of the machine head.

Claim 3

A machine according to claim 1, in which the drive for the table rollers is reversible.

Claim 4

A machine according to claim 2, in which the co-operating sets of rolls include cylindrically vertically disposed pressure rolls on one side of the stock, and driving rolls on the opposite side incorporating a cylindrical, vertical shaft portion upstanding from the said inclined surface.

Claim 5

A machine according to claim 3, in which the said other rolls having said inclined surfaces are disc-like idler structures.

Claim 6

A machine according to claim 3, comprising a pivotal arm on which each pressure roll is carried.

Claim 7

A machine according to claim 5, in which the machine head includes a grinding wheel for laterally traversing the stock.

Claim 8

A machine according to claim 6, comprising a first side gantry for depositing stock on the roller table at one end of the machine, and a second side gantry for Receiving discharged stock from the roller table at the other end of the machine.

Claim 9

A machine for removing surface defects from billet or bar stock, comprising; a grinding head, a grinding wheel in said head, a roller mechanism including a plurality of driven, horizontally disposed table rollers for reciprocably driving said stock into and out of engagement with the grinding head, and co-operating sets of rolls on each side of the head for laterally gripping the stock, at least one roll in each set and a plurality of other rolls in the roller mechanism aligned therewith having load bearing surfaces inclined to the horizontal plane to provide edge support for the stock on its leading and trailing ends in dependence on the stock shape, and control means for controlling both the rate of drive of the stock along the roller mechanism and lateral traversal of the grinding wheel over the stock as the stock is advanced past the head.

Claim 10

A machine for removing surface defects from billet or bar stock, comprising; a grinding head, a grinding wheel in said head, a roller mechanism including a plurality of driven, horizontally disposed table rollers for reciprocably driving said stock into and out of engagement with the grinding head, and co-operating sets of rolls on each side of the head for laterally gripping the stock, at least one roll in each set and a plurality of other rolls in the roller mechanism aligned therewith having load bearing surfaces inclined to the horizontal plane to provide edge support for the stock on its leading and trailing ends in dependence on the stock shape, and control means for controlling both the rate of drive of the stock along the roller mechanism and lateral traversal of the grinding wheel over the stock as the stock is advanced past the head.

Claim 11

A machine according to claim 8, in which the co-operating sets of rolls each include a cylindrical, vertically disposed pressure roll on one side of the stock, and driving rolls on the opposite side, each of said driving rolls incorporating a cylindrical, vertical shaft portion upstanding from a load bearing surface inclined to the horizontal plane.
