ABSTRACT:
A matrix of thin, deformable component elements is advanced by a mechanism so that at least the most immediate element of the matrix is maintained registered and non-deformed during translation. The mechanism includes a circumferentially faceted wheel, with teeth protruding radially from the facets for engaging holes in the matrix and indexing the matrix when the wheel is rotated. A rectangular plate pivoted about one end and arranged to rotate with the wheel has a surface which engages one facet of the wheel parallel thereto. The plate clamps the matrix between the plate and wheel precluding relative motion of that element with the wheel during rotation of said wheel and precluding deformation of the elements during such rotation or translation.
