<p>The axial position of the shutter is adjustable in relation to the conical shaft (2). A sleeve-shaped fitment (6) which slides over the conical bolt (3) has an outer surface, or the outer surface of an intermediate plastic sleeve, forming the bearing surface for the band-sleeve (13). The sleeve-type fitment is joined to the conical shaft. Between the fitment and the band-sleeve or band tabs is a manually operated snap-in connection for temporarily fixing at least one relative position of the band-sleeve in relation to the conical bolt.</p> |
