There is provided a feed roll assembly according to one aspect. The assembly includes a feed roll and an elongate mount coupled to and extending radially outwards from the feed roll. The assembly includes an elongate mount with a recessed region extending from a distal edge towards a proximal edge thereof, extending from a first face towards a second face thereof, and extending between a pair of spaced-apart ends thereof. The assembly includes an insert shaped to matingly engage with the elongate mount via the recessed region of the elongate mount.

There is also provided a feed roll assembly according to another aspect. The feed roll assembly includes a feed roll, an insert and an elongate mount that couples the insert to the feed roll. The elongate mount is shaped to enclose a proximal edge, a backing face and spaced-apart ends of an inner portion of the insert.

A feeding device includes a plurality of driving modules, a plurality of feeding modules and a plurality of couplers. Each driving module has a driving shaft pivotally mounted on a housing and driven by a power module to be rotated about an axis. Each feeding module includes a pivoting shaft substantially coaxial with the driving shaft, a suspending unit journalled on the pivoting shaft to be pivotable and having a bearing portion which is disposed to be biased downwardly by a spring member, a driven shaft mounted rotatably on the bearing portion, and a feeding roller driven by the driven shaft. Each coupler includes a transmitting shaft having two ends connected to the driving shaft and driven shaft by universal joints, respectively.

A sawmill and method for sawing a log. The sawmill includes a transfer conveyor to convey a log quarter wedge segment to a log transport rig configured to orient the log quarter wedge segment so that an apex of the log quarter wedge segment is oriented in a downward direction. The log transport rig moves the log quarter wedge segment through a band saw configured to saw the log quarter wedge segment into two log eighth wedge segments. A transfer conveyor is provided to gather the two log eighth wedge segments from the log transport rig and feed the two log eighth wedge segments sequentially to a resawing rig comprising a conveying device and from two to six band saws configured to saw boards from the each of two log eighth wedge segments in succession as each of the two log eighth wedge segments are transported through the resawing rig.

A remote control power tool for a working material including a support configured to support the working material, a power tool fixed to the support, at least one actuator configured to move the working material, a user interface remote from the power tool, a controller communicably coupled to the user interface, video camera proximate the power tool, and a visual display proximate the user interface.

A log handling device, having a rotatable rotor provided with log handler, and a feeder attached to the rotor for conducting an operating medium to the log handler. The feeder is arranged to wind around the rotor when the rotor is rotated in a first direction, and which feeder is arranged to unwind from around the rotor when the rotor is rotated in a second direction. The log handling device includes a rotatable second rotor to which the feeder is attached, and an operating device for rotating the second rotor synchronously with the rotor, such that the feeder is arranged to wind around the second rotor when the rotor is rotated in the second direction, and that the feeder is arranged to unwind from around the second rotor when the rotor is rotated in the first direction.
