    FIG. 1 and FIG. 2 show an embodiment of a wire saw according to the invention.
    1 shows a wire saw with a sawing unit for extracting a solid workpiece, the sawing unit having a sawing wire 1 provided with diamond segments and a guide device for the sawing wire 1. The guide device has two spaced-apart longitudinal arms 2, on which the sawing cable 1 is guided on. By the distance between the two longitudinal arms 2, the possible cutting width of the wire saw is defined, wherein the distance between the two longitudinal arms 2 is mutually variable. The two longitudinal arms are formed by telescopic arms whereby the longitudinal extent of the longitudinal arms 2 is variable. Possibilities of changing the spatial extent is indicated in the figures with a double arrow. At the ends of the two longitudinal arms 2 deflection rollers 3, in which the sawing wire is guided, arranged.
    In order to be able to change the spatial extent of the sawing unit, wherein the sawing cable 2 retains the desired cable tension, a cable store 4 and a cable tensioner 5 are provided, which guide rollers 6, in which the diamond cable 1 has been guided several times * * • · · · · · »· · "
    is, has. The distance between the Umenkrollen 6 of the rope store 4 and the cable tensioner 5 iast verabarerbar.
    The wire saw is arranged on a carrier device 1, which is mounted displaceably on tracks 8.
    The use of the device according to the invention can be represented for example as follows:
    In the area of the workpieces to be removed tracks 8 are placed and aligned with a spirit level. Subsequently, a drilling and milling unit (not shown) are lifted onto the tracks 8. The drilling unit is pivoted to the cutting direction, moved to the required position of the borehole and aligned accurately. The borehole can now by means of. Drilling unit to be driven to the desired depth.
    Subsequently, the milling unit is pivoted to the borehole and adjusted exactly to the borehole. The cutter with a driven diamond rope ·, which drives the cutter on the one hand and on the other hand next to the milling head itself milling effect, now milled with feeding cooling water a well defined in width and length shaft to the borehole deepest. The borehole serves as a guide and drainage of the cooling and sludge water. Vertical drilling requires a horizontal well to guarantee drainage. This hole or shaft, together with another hole, is required for further removal by means of a mobile wire saw. The router is driven out. The device comprising the drilling and the milling unit now travels over the tracks 8 to the second desired drilling and milling point. When the drilling and shunting is completed, the combined drilling and milling unit moves to the side and the wire saw (hoisting saw) is lifted onto the track 8 or moved on the track 8. The wire saw is moved to the desired point of intersection and by a device for changing the spatial orientation of the saw unit and by a device for changing the spatial extent of the • Μ ·· · · t * · I Μ · · · «· * ·« · « V ♦ · »· * sawing unit precisely aligned with the two drill holes or shafts. The telescopic arms of the wire saw dive into the two holes. The wire saw now begins by means of the diamond rope 1 to saw out the stone block to be removed from the mountain under rope pressure between the two shafts to the deepest point of the shaft while supplying cooling water. While the first tee is sawn, the combined drill and mill begins with the next drill holes or shafts. Thus, the combined drilling and milling unit always precedes the wire saw and the wire saw follows the same track. Once the saw has finished its cut, it drives on track 8 to the next drilled holes or shafts and the last track segment can be dismantled behind the wire saw and reapplied before the combined drilling and milling unit.
    If the deflection rollers 3 immersed in the mountain are formed by a milling head, no additional milling cutter has to be used. In this case, in particular if smaller cuts can be made, it is sufficient if a drilling unit and the immersion wire saw according to the invention are used.
    The device according to the invention can also be used in tunnel or tunnel propulsion.
    In summary, an embodiment of the invention can be represented as follows:
    A wire saw for extracting, for example, a stone block from a mountain, has a sawing unit, wherein the sawing unit has a sawing wire 1 provided in particular with diamond segments and a guide device for the sawing wire 1 and wherein the sawing wire 1 is driven. The guide device has at least two spaced-apart longitudinal arms 2, on which the sawing cable 1 is guided on. The rope saw will be dismantled in front of a ·· ♦ I · · · · · ··
