A machine including: a table having a surface adapted to have a workpiece lay and move thereon, and a vise for gripping the workpiece. The machine also includes a drive system for moving the vise and workpiece a distance along the table surface, and a sensor assembly connected to the vise for measuring an amount of slip distance occurring between the vise and the workpiece. The machine also includes a control unit connected to the sensor assembly and the drive system for storing the measured slip distance and for operating the drive system and for operating to do at least one of, when a predetermined amount of slip distance is detected: sounding an alarm and stopping further movement of the workpiece, and, when a slip distance is measured, for causing the drive system to move the vise and workpiece an added distance equal to the measured slip distance.

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.

A method for sawing a metal tube 3 or hollow section using a band-saw machine which has a stationary lower saw part 1 having a saw table 2 for placing and fixing a metal tube 3 to be sawn, and an upper saw part 4 which is movable in relation to the lower saw part 1 and which has a revolving saw band 5. The revolving saw band 5 via a feed motion 13 of the upper saw part 4, which is performed in relation to the lower saw part 1, penetrates the metal tube 3 and, for performing a saw cut, is guided through said metal tube 3. The feed motion is carried out substantially counter to the force of gravity.

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.

A support plate adjustment structure of a vertical band saw machine includes a workbench and a support unit. The workbench includes a rail seat fixedly connected to the workbench, a linear slide rail on the rail seat, and a slide slidably connected to the linear slide rail. A retaining plate assembly is provided between the workbench and the rail seat. The retaining plate assembly includes a first retaining plate and a second retaining plate. The support unit includes a support plate and a connecting seat connected to the slide. The support plate is connected on the connecting seat. The connecting seat can be locked or unlocked. The structure enables the support plate to be more stable, without wobble, and has better applicability.

A vise to be attached to a reciprocating saw includes a chain, a vise base, a tightening tool, and an elastic member. The chain includes a pin and is to be wound around a work material. The vise base is to be brought into contact with the work material and includes an insertion space into which the pin is inserted and a recess provided in the insertion space and in which the pin is hooked. The tightening tool is to be operated to pull the chain wound around the work material and is coupled to the chain. The elastic member prevents the pin hooked in the recess from dropping.

A benchtop band saw including a base, a clamp assembly configured to hold a workpiece, a support arm pivotably coupled to the base about a miter axis extending perpendicular to the base, and a band saw moveable relative to the support arm and the base between a raised position and a lowered position for performing a cutting operation. The band saw has a housing defining an opening in which the workpiece is partially receivable, a motor, a first wheel supported by the housing for rotation about a first wheel axis, a second wheel supported by the housing for rotation about a second wheel axis, and a band saw blade. The miter axis is located within a reference plane oriented parallel to the first wheel axis and the second wheel axis. The reference plane extends through the opening when the band saw is in at least the lowered position.
