A profiling saw with band knife loop take-up and payoff compensation includes an endless circulating band knife which is guided around a plurality of band knife pulleys so the take-up and payoff adjustment is provided of the loop circulation path shape. The take-up and payoff system operates to move a pulley in the vertical plane for allowing the band knife to maintain its cutting orientation during movement and providing for more rapid and precision cuts into a workpiece.

A method for sawing metal workpieces uses a sawing machine having a bench and clamping jaws, and an upper saw generates a sawing feeding movement in a cutting plane. The method includes: controlling the clamping jaws to clamp a workpiece, the clamping jaws located in an initial position; waiting input of an offset value, corresponding to a distance of a front end side of the workpiece from a zero position, into the machine controller, the zero position being a position in which the front end side of the workpiece is located in the cutting plane; advancing or retracting the clamping jaws to move the workpiece into the zero position; opening the clamping jaws; moving the clamping jaws to the initial position; re-clamping the workpiece located in the zero position, the clamping jaws being in their initial position; moving the clamped workpiece from the zero position into a cutting position, the cutting position being a position in the cutting plane where the workpiece is intended to be sawn.

There is provided in a preferred embodiment an apparatus for feeding an elongated material in a direction substantially generally along a length thereof to a cutting device having a cutting surface. The apparatus includes a lifting base assembly and a material shuttling assembly secured on the pivoting base assembly, the latter defining a feeding path. The lifting base assembly has a lower base portion and an upper base portion hingedly coupled to the lower base portion along a base pivoting axis generally parallel to and laterally offset from the feeding path. The upper base portion is selectively rotatable about the pivoting axis relative to the lower base portion between a level position and a lifted position, wherein in the lifted position, the material is raised above the cutting surface in an angled orientation where the material is further raised along a first lateral end portion relative to a second lateral end portion opposed to the first lateral end portion, the second lateral end portion being proximal to the pivoting axis.

A bread conveying apparatus includes a flight conveyer including a first flight for urging a bread, an endless revolving member on which the first flight is mounted, and a driving member and a driven member, the endless revolving member being wound around the driving member and driven member, a rail extending along a conveying path of the bread and supporting the first flight, and a rail size setting unit for setting a length of the rail with respect to an extending direction of the conveying path. The length of the rail with respect to the conveying direction is set by the rail size setting unit based on a size of the bread.

In order to improve a saw device with a feed axis for a workpiece to be sawed, with a first saw unit to saw the workpiece in a first sawing plane extending transversely to the feed axis and with a second saw unit to saw the workpiece in a second sawing plane extending transversely to the feed axis, with a central device region arranged between the sawing planes, with a front device region arranged in front of the first sawing plane, viewed in a feed direction, and with a rear device region arranged behind the second sawing plane, viewed in the feed direction, in such a way that as high a cutting efficiency as possible can be achieved, it is proposed that the saw device comprises at least two transport mechanisms arranged in different device regions to transport different workpiece portions along the feed axis.

A double-saw band saw machine includes a base, a first band saw unit, a second band saw unit, a feeding unit and a clamp unit. When an object to be sawn is located in a sawing area between the first and second band saw units, the first and second motors control the first and second frames to move toward each other along the first axial direction, so that the first and second band saw blades can be used to cut the object to be sawn simultaneously. Hence, the sawing efficiency of the double-saw band saw machine is improved, and the replacement interval for the first and second band saw blades is extended.
