Clamping means (40, 60) is mounted onto the head (24) from the end thereof remote from the blanket (22). In one version the head (24) itself is provided with a wedge surface in engagement with respective inclined surfaces of wedge segments (30) and the blanket (22) extends between these wedge segments (30) and opposing surfaces provided on the clamping means (40). Axial displacement of the clamping means (40) relative to the head (24), e.g. by tightening or releasing of bolts (46), then causes the blanket to be clamped between the wedge segments (30) and the clamping means (40) or to be released and removable therefrom. In another version, it is the clamping means (60) which is provided with wedge surfaces in engagement with respective inclined surfaces of wedge segments (50), and the blanket (22) then extends between the wedge segments (50), and an opposing flat surface on the head (24). However, in other respects axial displacement of the clamping means (60) brings about clamping or release of the blanket (22) edge in the same manner. <IMAGE> <IMAGE>
