Device for processing or sharpening the steel edges of skis

The motor-drivable belt grinding device is intended to replace the files used previously for smoothing the surface of edges of skis. For this purpose, the belt grinding device has been fitted with an adjusting device, with the aid of which the sliding block which is otherwise attached rigidly to the machine frame and receives the contact pressure of the material-eroding belt strand is mounted both so as to be variable in its basic setting parallel to the belt and so as to be inclinable about an axis disposed parallel to the belt running direction. Incomparably improved operating results have thus been achieved in respect of the surface finish of the steel edge surface, and the time required for carrying out any necessary repair work has been reduced considerably.

Tool Having Composite Housing

A power tool includes a tool housing and a mechanism disposed inside the tool housing. The tool housing has a composite structure that includes an outer layer and an inner layer. The outer layer provides an outer surface of the power tool housing and comprises a first material. The outer layer is an assembly of concave shell portions joined along parting lines. The inner layer is disposed on an inner surface of at least a portion of the outer layer so as to be disposed between the portion of the outer layer and the mechanism. The inner layer comprises a second material. The first material has a density that is at least three times the density of the second material. The inner layer has a peripheral edges that are offset relative to the parting lines such that the inner layer extends continuously across the parting lines. 2. The power tool of claim 1 , whereinthe outer layer is an assembly of a concave first shell portion and a concave second shell portion,the first shell portion is joined together with the second shell portion along a first parting line to provide an enclosed interior space that receives the mechanism,the inner layer is disposed between the portion of the outer layer and the mechanism, andthe inner layer has a first peripheral edge portion that is offset relative to the first parting line such that the inner layer extends continuously across the first parting line.3. The power tool of claim 2 , whereinthe outer layer is an assembly of the first shell portion, the second shell portion and a concave third shell portion,the third shell portion is joined together with the first shell portion and the second shell portion along a second parting line to provide the enclosed interior space that receives the mechanism, andthe inner layer has a second peripheral edge portion that is offset relative to the second parting line such that the inner layer extends continuously across the second parting line.4. The power tool of claim 3 , wherein the inner layer is ...

Power Tool

A power tool which brakes a motor without turning off a trigger switch when a trouble occurs in the motor is provided. The power tool () comprises: a motor () that rotates by supply of electricity from a power source (PS); a controller () for controlling the rotation of the motor; a switch () for switching on and off of power supply from the power source to the motor manually; first braking means () for braking the motor when the switch () is switched from on to off; and second braking means () for braking the motor () on the basis of a prescribed signal from the controller when the switch () is in an on state. 1. A power tool comprising:a motor accommodated in a housing, the motor rotating with electric power supplied from a power source;a control circuit configured to control rotation of the motor;a switch configured to be manually switched between on and off of power supply from the power source to the motor;a first braking part configured to brake the motor when the switch is switched from on to off; anda second braking part configured to brake the motor on the basis of a predetermined signal from the control circuit when the switch is in an on state, whereinthe first braking part comprises a first closed circuit formed when the switch is switched,the second braking part comprises a second closed circuit generated by the control circuit, andthe first closed circuit and the second closed circuit are provided at the control circuit.2.
