A method for forming grooves in a board element. An exemplary method includes arranging the board element in contact with a support member, and forming at least one groove in a rear side of the board element by removing material, such as chips, from the board element by rotating one or more cutting devices including a plurality of tooth elements configured to rotate around a rotational axis. A method further includes counteracting, such as preventing, a displacement of the board element away from the support member during forming of the at least one groove, wherein the counteracting, such as preventing, includes arranging at least a portion of the board element between an obstruction element and the support member.

The disclosure includes a protective device for a machine, a method of operating a protective device, and a protective system including the protective device and the machine. The protective device may include a sensor array disposed on the machine. The sensor array may have a plurality of time-of-flight (TOF) sensors arranged to form a sensible field for TOF measurements, and a controller configured to define a safety area within the sensible field, detect an object within the sensible field, and generate a safety output that controls an operation of the machine in response to the object being detected within the safety area. The machine may include woodworking machines or other machines having debris or particles in the surrounding environment during operation.

A safety system with a number of component devices that may be used alone or in combination to substantially reduce the risk of injury to the operator of the power cutting tool. The devices are designed for use with table saws, miter saws, jointers, routers, shapers and similar equipment. The devices secure a work piece against unanticipated movement and kickback while simultaneously protecting the operator's hands. The devices further enhance the capabilities of power equipment to make precise cuts safer, faster and easier. According to aspects of the present disclosure, one such device includes a guide member for engaging a work piece and an adjustable alignment member for orienting the position of the guide member relative to a cutting blade.

An apparatus for mechanically splitting materials has a body with a cutting element arranged relative thereto. The cutting element has at least one cutting surface oriented vertically. The splitting apparatus has the cutting element applying an upward pressure against the material which is split when a separate downward force is applied to the material. The body of the splitting apparatus also has a safety element to protect the user from the cutting element; an elongate supporting element to distance the safety element from either or both the cutting element and a surface on which the splitting apparatus is used; a stabilizing element to stabilize the splitting apparatus relative to a surface on which the splitting apparatus is used; and optionally a deflecting element to deflect split materials away from the cutting element and container element to contain therewithin split materials produced during the splitting.

A safety device (10) for monitoring an industrial machine or plant (100) comprising an electric motor (101). The safety device (10) comprises a detection unit (11) apt to detect at least a first physical quantity related to the operation of the electric motor (101) and a second physical quantity related to the movement of the load (105), a signaling unit (13) configured to transmit a safety signal(S) generated by a processing unit (12). The processing unit (12) is configured to compare the at least two physical quantities with each other in order to detect faults or anomalies and generate the safety signal(S) based on the said comparison.
