Abstract
1480495 Coiling spirals H J LAZARUS 25 July 1974 [26 July 1973] 25288/76 Divided out of 1480494 Heading B3E A winding member 88 for tightening a preformed coil 36, provided on a dental matrix band having the subject of the parent Specification (see Division A5-A6) is generally frustoconical with a flat smaller diameter end face 100 and a plurality of rectilinear projections which extend between opposite ends. The projections may be unidirectional and have teeth 96. The projections may have chambers 94 where they adjoin the flat end face 100. In use the projections grip the interior of the coil when the member 88 is rotated in one direction for tightening the coil. The member 88 is mounted on one end of a flexible shaft which is rotated by a manually rotatable sleeve on a handle having a portion for holding in the palm of the hand.
