Tape splicing blocks

Claim 1

A splicing block assembly for supporting ends of a plurality of tape-like items to be spliced, said assembly comprising, in combination: a stationary block having a first guideway for receiving one of said tape-like items; a rotationally movable block adjacent said stationary block, said movable block having a second guideway and a third guideway for receiving a pair of said tape-like items, said movable block being rotatably supported so as to be capable of rotation on an axis parallel to and substantially equidistant from said first, second, and third guideways, said movable block having first and second prismatic faces substantially parallel to said axis; means for rotating said movable block on said axis selectively in a first direction and a second direction; and alignment means limiting rotational motion of said movable block between a first position wherein said first and second guideways are colinear and a second position wherein said first and third guideways are colinear, said first and second positions being determined by the alternate contact of said first and second prismatic faces on said movable block with a stationary member secured to said stationary block.
