Title: Hot rotary stamper apparatus and method for metal leaf stamping
Inventor: ANGEL AMENDOLA
IPC: B41F19/06
Filed: 1991-04-16
Granted: 1999-06-01
Abstract: A continuous sheet 27 of metal leaf advanced at a constant rate is moved at variable velocity through a rotary die stamper 6, 7 such that between stamps the metal leaf moves at a velocity which is slower than the velocity of a substrate web 28; but just prior to stamping the metal leaf is accelerated by contact between the metal leaf sheet and a raised die 5 rotating at the velocity of the substrate web so that when the stamp occurs the metal leaf sheet is travelling at a velocity substantially equal to the velocity of the substrate web. Varying the velocity of the metal leaf sheet has the effect of minimising the distance the metal leaf sheet travels between stamps which conserves consumption of the metal leaf sheet. Separate means for accelerating the leaf sheet prior to stamping and decelerating the leaf sheet after stamping may also be provided. <IMAGE>
