A safety feeder usable with different woodworking machines includes a fixing frame releasably mountable on a woodworking machine. A device connects to the fixing frame. The fixing frame cranes the device. The device includes a drive device, a transmission system, and at least one first and second pressing rollers. The drive device engages with and is able to drive the at least one first and second pressing rollers through the transmission system. The transmission system includes an axle engaging with the at least one first and second pressing rollers. The at least one first and second pressing rollers are disposed separately in an axial direction with a predetermined gap on the axle.

A circular saw machine contains a first clamping device, a second clamping device, a holding plate, a feeding means, and a sawing device. The first clamping device includes a first clamp mount, a movable clamp block, and a first upper clamp block, the first clamp mount has a first fixing arm, a first holder, a placing portion and a first fixed clamp block. The second clamping device includes a second clamp mount, a second movable clamp block, and a second upper clamp block, the first clamp mount has a second clamp arm, a second holder, and a second fixed clamp block. The holding plate is secured on a top end of the second clamp arm. The feeding means is disposed on the first clamping device. The sawing device includes a saw disc.

A tile or masonry saw assembly may include a saw, a frame, and a workpiece support. The saw includes a motor operable to turn a blade assembly to cut a workpiece. The frame is operably coupled to the saw to enable the saw to be moved along the frame in a first direction. The workpiece support is operably coupled to the frame to support the workpiece relative to the saw, and to allow the workpiece support to be moved along the frame. The saw assembly further includes a movement assembly via which both movement of the workpiece support and movement of the saw relative to the frame is accomplished, such that a movement of the work piece support along the frame in a second direction is enabled to cause the saw to move along the frame in the first direction which is opposite the second direction.

A table saw having a stationary blade and a parallel moveable blade for straightening uneven dimensional lumber of the type used in cabinetry and other relatively fine woodworking. The table saw has a workpiece support frame with a lateral blade opening allowing the moveable blade to be shifted laterally and adjust the spacing between the blades. Powered feed rollers located above the table are used to clamp and feed a workpiece through the table while preventing kickback. A sacrificial fence including a blade guard recess is associated with the stationary blade, and includes a shutoff switch automatically activated to disable the stationary blade for solo use of the moveable blade.

Various dust collection apparatuses are disclosed, which include a vacuum source, a circular saw blade, and a worktable comprising a center slot axially aligned to the circular saw blade. In a first aspect, the center slot includes an air flow channel proximate to an anticipated point of contact between the circular saw blade and a workpiece, and the vacuum source is configured to provide a focused negative pressure beneath the worktable via the air flow channel In another aspect, the vacuum source provides a negative pressure beneath the worktable at the center slot, and a multistage filter is included to collect airborne dust drawn by the negative pressure from an area proximate to the center slot. In yet another aspect, the vacuum source is configured to provide a first negative pressure beneath the worktable at the center slot, and a second negative pressure via an auxiliary port.

A table saw includes a base table, a sliding table, and a carriage. The base table includes a first and second guide rail. The sliding table is configured for movement relative to the base table. The sliding table includes a third guide rail and a fourth guide rail. The carriage includes a support frame and at least four rollers configured for rotation relative to the support frame about corresponding axes of rotation. A first roller and a second roller of the at least four rollers are configured to receive the first guide rail and the third guide rail, and a third roller and a fourth roller of the at least four rollers are configured to receive the second guide rail and the fourth guide rail. The axes of rotation are substantially parallel. The carriage is configured for movement relative to the base table and the sliding table.

A table saw includes a base assembly, a table assembly supported by the base assembly, a saw blade, and a saw assembly supported by the table assembly. The saw assembly includes a motor having a motor output shaft, a power train assembly with an arbor shaft to which the saw blade is fixedly connected, an intermediate shaft, a first gear stage connecting the motor output shaft to the intermediate shaft with a first gear ratio, and a second gear stage connecting the intermediate shaft to the arbor shaft with a second gear ratio that is less than 1.25. The saw blade has a diameter of 254 mm and the saw blade extends by up to 102 mm above the support surface in a maximum cutting height position of the saw assembly.
