Abstract:

A device primarily for use by silversmiths and hobbyists for crimping a relatively thin strip of metal for jewelry creations and crafts. A pair of discs each have a centrally mounted pinion gear extending outwardly from a flat face of the disc. The gears are received within an annular collar having an elliptical cross-sectional configuration which houses the gears in meshing relationship and separates the discs. A pair of aligned holes is formed in the collar for receiving and discharging a strip of metal which is fed between the meshing gears and crimped when the discs are manually rotated. The collar is adjustable to regulate the crimp depth by varying the elongation of the collar by mechanically pressure squeezing the same.
