to the present invention may be better understood with reference to the drawings and the accompanying description referring now to the drawings fig1 a and 1b illustrate a gripper according to a preferred embodiment of the present invention there is seen a beam 13 which is part of a carrier assembly not shown to be described herebelow on beam 13 are mounted a plurality of gripping assemblies to be referred to as grippers 10 each gripper 10 consists of a chuck 14 fixedly attached to beam 13 and a pair of pinching fingers 12 each pinching finger 12 is formed as a slightly curved spring blade made of suitable elastic material preferably stainless spring steel such as type 302 304 preferably both blades in a pair are identical and are formed so as to be inter lockable at one end 16 for example as illustrated in fig2 a they are shown interlocked in fig2 b each finger 12 or blade has at one end which is opposite the interlocking end a tip 11 which is preferably coated with a soft high friction substance such as neoprene rubber chuck 14 is preferably made of a durable material such as acetal that has a low but finite factor of friction and is formed to have an aperture in the form of a slot 15 cut lengthwise therethrough its length is substantially less than that of fingers 12 conveniently chuck 14 may be assembled from two halves in which slot 15.
