PCT No. PCT/US94/11783 Sec. 371 Date Apr. 3, 1996 Sec. 102(e) Date Apr. 3, 1996 PCT Filed Oct. 17, 1994 PCT Pub. No. WO95/10988 PCT Pub. Date Apr. 27, 1995According to the present invention there is provided an instrument for measuring the tightness between a first and a second contiguous bodies, the first body being movable with relation to the second body, comprising: (a) a substantially incompressible insertion element of predetermined thickness for insertion between the first and second bodies; (b) a holder for holding the insertion element to enable the insertion element to be forcibly inserted between the first and second bodies, thereby displacing the first body with relation to the second body, thereby providing a predetermined forced distance between the first and second bodies; and (c) a sensor for sensing the insertion force applied when inserting the insertion element between the first and second bodies along a predetermined path of insertion. Further according to the present invention there is provided a method of measuring the tightness between a first and a second contiguous bodies, the first body being movable with relation to the second body, comprising the steps of: (a) forcibly inserting a substantially incompressible insertion element of predetermined thickness between the first and second bodies; and (b) simultaneously measuring the insertion force required for displacing the first body with relation to the second body so as to provide a predetermined forced distance between the first and second bodies, wherein said measuring is performed along a predetermined path of insertion by means of a sensing element.
