There is disclosed a spindle for incorporation in a clinching apparatus, comprising: a first shaft (44) rotatable about its own elongate axis; a second shaft (46) rotatable about its own elongate axis; a coupling means (45) which allows the second shaft (46) to be flexibly coupled to the first shaft (44) in a manner such that rotation of the first shaft (44) about its own axis causes rotation of the second shaft (46) about its own axis, and such that the axis of the second shaft can adopt a non-rectilinear relationship with respect to the axis of the first shaft (44); and an elongate resiliently flexible member (47) capable of acting so as to tend to urge the axes of the first and second shafts (44 and 46) to adopt a rectilinear configuration. Also disclosed is an apparatus suitable for fitting a seal having a channel-shaped portion onto a flange which can vary in thickness along the length of the flange, which apparatus comprises: a housing (2, 3 and 4); two rotatable spindles (10 and 11) carried by the housing (2, 3 and 4), preferably with at least one of the spindles (10 and 11) being a spindle as described above; and means (41 and 42) within the housing for causing rotation of the spindles; with provision for the two spindles to move apart in the plane in which they are located. <IMAGE> |
