Abstract: A device for setting saw blades has a housing, a setting device connected to the housing for setting a saw blade, a clamping device connected to the housing for clamping the saw blade, and a drive unit connected to the housing for driving the setting device and the clamping device. The setting device has saw set holders which are arranged on either side of the saw blade, are pivotable relative to one another and can be fitted with saw sets. The clamping device has clamping jaw holders which are arranged on either side of the saw blade, can be adjusted relative to one another and can be fitted with clamping jaws. In order to provide a device of the kind described above, which securely clamps the saw blade, the clamping jaw holders are designed so as to be pivotable relative to one another.

Abstract: A clamping device (1), particularly a machine vice (1), has a body element (2), a jaw (3) attached thereto, and an oppositely placed movable jaw, for displacement by a drawbar (4). The drawbar has a compression bar to be arrested at varying distances from the fixed jaw, and a force amplifying arrangement (5) acting on the spindle. The force amplifying arrangement includes at least one cylindrical tube (9) and at least two plungers (10, 11) that are movable in concentric cylinders. Two compression chambers are provided, an outer, low-pressure chamber (12) and a high-pressure chamber (14) acting on the clamping plunger (11) from the direction of the drawbar, wherein a functional connection is established between the two plungers so that at least one rod (18) having a smaller diameter than the diameter of the plungers and connected to the outer compression plunger (10) acts on the high-pressure chamber (14), which is filled with pressurising medium, preferably oil or liquid grease.

Abstract: The invention relates to a tensioning device, in particular a machine vice, with a base body, with a stationary jaw attached thereto and with a movable jaw opposite this, for whose adjustment there is provided a tension rod, wherein the tension rod comprises a support bearing via which the movable jaw is supported by way of a compression rod. The object of the invention is to specify a tensioning device which permits a quick tensioning also of differently dimensioned subjects and furthermore offers the largest possible protection from contamination of the functional parts. This object is achieved in that the movable jaw is formed lockable at various distances to the stationary jaw with the compression rod, preferably by way of clamping bodies.

Abstract: In order to obtain a simple, inexpensive and low-maintenance monitoring device for controlling the setting width of individual teeth of saw blades or belt-saw blades, in particular for controlling the setting result of a setting machine the present invention invisages that the monitoring device comprises at least one photo-detector whose light beam at least partly runs through one or both regions laterally next to the running-past saw blade or belt-saw blade, into said regions the set teeth project.

Abstract: The invention relates to a device for setting saw blades or belt-saw blades with clamping jaws arranged on both sides of the saw blade or belt-saw blade and with setting tools arranged on both sides and pivotable about an imaginary axis. It is the object of the invention to put forward a new device with which the setting result may be improved. According to the invention the object is achieved in that in horizontally displaceably mounted guiding blocks arranged on both sides of the saw blade or belt-saw blade there is pivotably mounted in each case a setting tool mounting formed as circle segment, wherein the guiding block is designed simultaneously as a clamping jaw for fixing the saw blade or belt-saw blade, and that displacement devices are provided for the horizontal displacement of the guiding blocks.
