<p>The invention relates to a bellows (1) for a machine tool in order to protect against contamination, wherein the bellows (1) has a longitudinal direction (L) and the length of the bellows (1) is adjustable in the longitudinal direction (L), the bellows (1) consists of a fabric (7) which, in the stretched state of the bellows (1), has a first thread (8) in the longitudinal direction (L) and a second thread (9) at right angles to the longitudinal direction (L), the bellows (1) has at least a first bellows member (11) having a first external fold (2a) and a second bellows member (12) having a second external fold (2b), wherein the first external fold (2a) and the second external fold (2b), as seen in the longitudinal direction (L), enclose an angle (a) which is not equal to 90°, and in the second bellows member (12), adjoining the first bellows member (11), there is provided a gusset (4), such that when the bellows (1) is pulled apart and pushed together in the longitudinal direction (L), the individual thread (8, 9) in the region of the gusset (4) has a deformation in particular as a result of a combination of twisting and bending movement.</p> |
