<p>The supporting member comprises a supporting bridge (42) having two vertical legs (44) whereof the lower ends (46) are supported on the machine table (10). The upper ends of the two legs (44) which receive the bearing block (24) are connected to one another by way of a cross-rail formed by way of two limbs (50) projecting horizontally from the two legs (44), one overlying the other so they may be altered to enable the inside width of the supporting bridge (42) between the two legs (44) to be adjusted to the local conditions.</p> |
