A self-dust extraction dustless table saw includes a table saw frame, saw table, and saw blade installed to the table saw frame. An upper and a lower blade guards are respectively mounted to upper and lower sides of the saw table, the saw blade is mounted in the upper and lower blade guards, and the lower blade guard includes a lower left and lower-right blade guards. Several interval guide barriers are installed on the inner walls of the lower left and lower right blade guards, and the guide barriers transport the dust to a dust outlet on the side of the lower right blade guard.

An improved cutting device with an integrated and interruptible auxiliary power supply. In a preferred embodiment, the improved cutting device is a miter saw having a trigger mechanism for controlling a cutting implement, and at least one 120V or 240V auxiliary power outlet. Electrical power is only provided to the cutting implement and the auxiliary power outlet when the triggering or a similar mechanism is activated, and the release of the triggering mechanism by the user automatically shuts off electrical power to both the cutting implement and the at least one auxiliary power outlet. The auxiliary power outlet is useful for powering any number of different accessories including, without limitation, a light, vacuum source, etc., and is repositionable.

The object of the application is a cleaning system of a drum conveyor of a filter segment feeding apparatus in the tobacco industry wherein a transport drum (3) comprises a plurality of discs (4) on the circumferential surface of which concavities (5) are formed whereas the concavities of the individual discs are positioned relative to one another so that together they form channels (6) receiving filter rods (1), where in the said channels (6) the filter rods (1) are transported during cutting, whereas the borders of adjacent discs (4) do not contact one another and in this way they form circumferential grooves (9). The discs (4) have passages (12) discharging the dirt, the circumferential grooves (9) have a connection with the passages (12) discharging the dirt, and the system comprises a vacuum channel (15) receiving the dirt having a connection with the passages (12) discharging the dirt in the discs (4).

A power tool arrangement includes a frame having an outlet. A power tool is coupled to the frame and includes a movable working element configured to engage a work piece. A hose includes first and second opposite ends and a biasing device configured to bias the hose into a longitudinally compressed position. The first end is coupled to the outlet. The second end is coupled to the working element such that the second end follows the movement of the working element and the hose thereby moves between the longitudinally compressed position and a longitudinally expanded position.

A Dust Capturing Device for Reciprocating Saws is disclosed. The device is attachable to a convenational shop vacuum cleaner so that virtually all dust created by the reciprocating saw at the cutting blade is captured by the vacuum cleaner. The system is universally attachable to all powered reciprocating saws on the market. A pair of suction hoses are snugly attached to the body of the saw, from intake ports located adjacent to the saw blade to an adapter manifold that combines the two suction hoses into a single hose adaptable to the vacuum cleaner hose. The hoses are attached to the body of the saw by one or more body straps, with each body strap having a pair of hose clips extending therefrom for restraining the two suction hoses running along the body.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

A cutting equipment which trims strips of webs in movement includes a stationary trimming blade and a rotating cylinder with a mobile trimming blade; the rotating cylinder includes a sector with suction openings connected to a vacuum source, which retains the strips by suction and drags the strips up to a strip collector; the cutting equipment cuts and separates transversal strips of two webs overlapped in adherence jointly to the cutting of basic sheets; a perforating device perforates a row of holes on the first web adjacent to an edge of the sheets; and a first web is positioned with the row of holes in front of the suction openings, while the strip of the second web is retained and dragged by suction through the holes of the first web up to the strip collector.
