Abstract

The mechanical coupling device comprises a vertical spindle terminating in an eyebolt at the top end and a conical member (15) at the lower end. The conical member is surrounded by a ring of ball bearings (18), and the spindle is retained by a hollow tube, welded to a cage (16, 17). The balls press on an outer tube (21), so that an extraction force on the spindle causes the tube to expand and apply a pressure to a web of material (20) against which it presses. The device is especially applicable to emulsion coated photographic films.
