摘要： To sand the surface of an item (3) uniformly smooth, a sanding machine is used with sanding tools in the form of sanding rollers (29) which are rotated as well as turned in the same plane, and which at the same time are also moved in a different direction from the direction in which the item is conveyed, whereby during the working stroke the sanding elements on the sanding rollers (29) will sand at all possible contact angles in relation to the item (3).To move the sanding rollers (29), the apparatus comprises a motor-driven crank arm (7), in sliding engagement with a carriage supports the sanding rollers (29), and drives the carriage on rails (33) which extend in a circle about the machine (1). This achieves a stable and robust construction which also gives the sanding rollers (29) an expedient movement characteristic, which compensates for the predominantly longitudinal sanding movements to which the items are exposed in the outer areas.

摘要： A rotating grinding or polishing device includes a number of grinding or polishing discs formed of two or more layers of segments radiating from a central retaining area having an edge which defines a central hole. In the central area, the segments are kept together by a heat-activatable string which also maintains the grinding or polishing disc in the form of a ring, whereby the disc has the required optimum stiffness/flexibility for obtaining an effective grinding or polishing finish so that even complex surfaces can be effectively ground or polished.

摘要： A grinding- or polishing implement can be produced by providing a rectangular sheet (1) at both sides with segments (2) formed by slits from the outside towards the center. Hereafter the sheet is folded around the center across a glue string (5), and then the two folding edges are folded together and glued together for the formation of a closed ring. This ring can thereafter be placed on a spindle (6) preferably between retaining discs (8).In this way raw material can be saved in the production of rings, just as the rings can be used more economically in an implement as the grinding qualities are improved through the big number of segments, their completely uniform size and placing along the periphery of the implement and their ability to adjust and shape themselves according to the prepared members.An implement can be produced by disposing such rings between retaining discs (8) on a rotating spindle (6), and in order to secure the rings the spindle (6) can at its end have one or more guide facings (10), in which a co-operating guide pin (12) on a disc (7) can slide and be axially displaced by being tightened together with a bolt (11).

摘要： In order to be able to sand the surface of an item (3) uniformly smooth, a sanding machine is used with sanding tools in the form of sanding rollers (29) which are rotated as well as turned in the same plane, and which at the same time herewith are also moved in a reciprocating manner transversely to and parallel with the direction in which the item is conveyed, whereby during the working stroke the sanding elements on the sanding rollers (29) will sand at all possible contact angles in relation to the item (3). The risk of sanding damage such as marks and grooves as a result of over-sanding, or the possible lack of sanding as a result of too sporadic contact, is herewith reduced, and the best possible result is achieved.Furthermore, the wear on the sanding rollers (29) is completely uniform, whereby their endurance is extended.For the movement of the sanding rollers (29), there is used an apparatus comprising a motor-driven crank arm (7) which, in sliding engagement with a carriage which supports the sanding rollers (29), can drive the carriage forwards and backwards on rails (4) which extend transversely to the machine (1).There is hereby achieved a stable and robust construction which also gives the sanding rollers (29) an expedient movement characteristic, which compensates for the predominantly longitudinal sanding movements to which the items are exposed in the outer areas.

摘要： Workpieces having three-dimensional surfaces can be efficiently sanded by rotatable sanding members mounted on spindles which are supported for movement in a circle of revolution over the surfaces of the workpieces as the individual spindles are selectively rotated about their longitudinal axes in either of two opposite directions during predetermined portions of each circle of revolution. A sanding apparatus for accomplishing this function includes a cone clutch arrangement for selectively reversing the direction of rotation in accordance with a cam directed control arrangement acting on pivotally supported yokes carrying the individual spindles.

摘要： To be able to control the admission of compressed air or liquid to a machine in a hand tool, the working medium can be admitted to the machine through a handle with a built-in valve. By turning the handle (1) the valve opens or closes. The valve body itself (7,9) is secured to a stay in the form of a bolt (10) and a pipe (8) screwed into the bottom of the handle casing (1), whereas the valve seat (14) is formed as a recess in a bushing (2) being stationary relative to the casing. The handle has an oblique track (4) wherein a bolt (3) secured in the bushing moves the casing (1) and thereby the valve body relative to the bushing (2) when the handle is turned. When the handle is released in the open position of the valve (FIG. 3), the pressure exerted by the medium will move the casing so as to close the valve since the area of the casing is larger than that of the bush (2). The machine can thereby be safely and reliably disconnected by releasing the hold on the handle. The valve can be used for a hand grinder with a U-shaped handle pipe with handle ends and a hollow spindle situated between the handle ends, an air machine being arranged in the spindle. The spindle has a number of slotted grinding discs, and a pressure medium is admitted to the machine through passages in the handle pipe. A simple and reliable hand grinder which can efficiently grind deep profiles is thereby obtained.
