Abstract
A ledger assembly for a continuous rod cut-off includes a rigid beam (12) carrying ledger tubes (10) and pivotally supported by fibreglass springs (16,22). Vertical springs (22) resist the cutting force of the cut-off knife (30) and allow reciprocal movement of the tubes (10) while imparting a vertical displacement to the beam (12) so that the tubes follow a straight path along the rod line (28). A horizontal spring (16) allows this vertical displacement while providing lateral stiffness for the base of the beam (12). A drive arrangement for the beam (12) includes a lubricating system for a bearing (42) of a connecting rod (36) in which lubricant is collected for return by action of centrifugal force in a housing (72) located on the side of the bearing opposite a lubricant supply path (86, 88) through a crankshaft (40).
