A device for cutting pieces of wood to size, in particular meter-long logs, to form log pieces or firewood, has a frame for accommodating meter-long items. The frame comprises spaced-apart holding elements that are designed in a U shape and between which free regions for saw cuts are provided. It is possible for the frame to be shifted from a sawing position about a pivot axis into an unloading position.

An apparatus for supporting a molding article that is to be cut by a sawing device. The apparatus includes a bottom supporting surface having opposing front and rear edges and opposing first and second side edges. A first wall is included that is upstanding from the rear edge of the bottom supporting surface and substantially extends between the opposing first and second side edges of the bottom supporting surface. A second wall is upstanding from the bottom surface and at a location intermediate the first wall and the front edge of the bottom supporting surface. The second wall preferably extends between the opposing first and second side edges of the bottom supporting surface. Also preferably included is an adjustment assembly operatively associated with the bottom supporting surface and the second wall

A worktable of a workpiece finishing machine comprises a first worktable and a second worktable. The first worktable has a first joining portion. The second worktable has a second joining portion which is joined with the first joining portion to enable the second worktable to slide back and forth along a predetermined direction provided by the first joining portion, thereby resulting in a change in the area formed between the first worktable and the second worktable for placing a workpiece to be finished by the workpiece finishing machine. The worktable further comprises a locating device formed of an arresting member with a first friction portion, and an actuating mechanism which is mounted on the second worktable and is connected with the arresting member. The arresting member is actuated to move back and forth between a first position and a second position, so as to enable the arresting member to press against the first worktable to attain the effect of locating the second worktable.

A bagel or bun slicing apparatus includes a frame mounted to a vertically adjustable stand and base. The frame defines a vertical channel which houses a reciprocating blade and rollers for transporting the bagel or bun through the channel and across the blade. The rollers are rotated by an electric motor which also reciprocates the blade. The rollers and/or a guide plate may be laterally adjustable to allow for bagels or buns of varying widths.

Apparatus which can be employed for light, everyday hand-cutting of existing rolled material such as gift wrapping paper. The apparatus includes a frame whereon the roll of material can be positioned for rotary movement. The frame may be of fixed length to accommodate standard roll lengths or the frame may be made to be expandable if desired. A slot is provided to allow the material to be pulled therethrough. A cutter blade is disposed on the frame and is adapted to slide along a path parallel with the slot to perform a clean, even cut on the material.

A method for singulating a substrate containing semiconductor components is performed using a nest for holding the substrate, a prestage alignment base for aligning the substrate during a prestage alignment step, and a vacuum cutting base for holding the nest and the substrate during a cutting step. The prestage alignment base includes locator pins configured to engage locator openings on the substrate to align the substrate on the nest. As the cutting base does not include the locator pins, the cutting step can be performed without saw scrap collecting on the locator pins. A system for performing the method includes the nest and the prestage alignment base having the locator pins configured to engage the locator openings on the substrate. The system also includes the sawing base which includes pedestals with vacuum conduits for holding the substrate stationary on the nest for sawing. The system also includes the saws, and a vacuum source in flow communication with the vacuum conduit and pedestals on the sawing base.

A package opening cutter is provided which can accurately, safely and efficiently open the package without damaging the merchandise inside and in which the cutter will not come out during use. It comprises an angle ruler, retaining portions provided at both sides of the angle ruler, a clamp body provided so as to be pushed into and pulled out of the retaining portion for clamping a cutter, and means for preventing the clamp body from coming out of the retaining portion. The means for preventing the clamp body from coming out has a bolt slidably provided between the cutter retaining portion and the cutter clamp body. The bolt is operated by a knob provided on outer surface of the cutter retaining portion.

A workpiece support accessory in the form of a sloping extension panel is coupled for pivotal and horizontal displacement relative to a table-mounted power saw for supporting oversized stock. When an oversized piece of stock is cut, the extension panel prevents the workpiece from inadvertently falling or twisting. A horizontal roller at the delivery end of the workpiece support accessory reduces the friction between the oversized stock and work surface allowing for easy movement during the saw operation. The operator can adjust the horizontal placement of the workpiece support accessory, the slope angle of the extended support surface, the elevation of the horizontal roller and the separation between the horizontal roller and the delivery end of the extension panel.
