Apparatus for handling bar-like workpiece material in a sawing machine

An apparatus including a workpiece table and a machine frame for handling bar-like workpiece material in a sawing machine, in particular in a miter-box saw having a miter angle that is adjustable about an axis vertical to said workpiece table relative to a circular cold saw blade rotatable about a horizontal axis, said saw blade being displaceable from below said workpiece table through a pivotable slit in the workpiece table, a first pair of openable and closable clamping jaws immovably disposed on the workpiece feed side of the cutting plane of said saw blade in terms of the feed direction of the material, for retaining said material in place on said workpiece table during cutting and for releasing said material subsequent to being cut, a roller conveyor that precedes said workpiece table for feeding said material to be cut, one of said jaws of said first clamping jaws is disposed stationary in a vertical plane parallel to the material feed direction of the material, a vertically movable clamping jaw disposed on the machine in the vicinity of the cutting plane by means of which the material is clamped against the machine table during cutting,

• a movable clamping carriage (15) disposed above said workpiece table (2) movable on said machine frame (1) horizontally and parallel to the feed direction (9) of the workpiece material (36), two horizontally openable and closable bearing jaws (19, 20) disposed beside one another in the material feed direction on the clamping carriage and extending in a vertical plane, said bearing jaws (19, 20) are spaced apart by a mutual distance (24) allowing the passage therethrough of said saw blade (4) over an adjustable range of the miter angle (8), in the feed direction of movement of the workpiece material, said bearing jaws being openable and closable in a horizontal direction on the clamping carriage toward said workpiece material, and three movable clamping jaws (21, 22, 23), including two outer jaws and a middle jaw that cooperate with said bearing jaws for gripping said workpiece material, said three clamping jaws all disposed beside one another in the material feed direction, and a mutual spacing distance between said edges oriented toward one another of said two outer clamping jaws (21, 23) dimensioned such that for a largest possible cross section of the workpiece material, these said two outer clamping jaws are located outside a working range of said saw blade when given a maximum miter angle (8).
