Abstract
An insertion method for introducing at least one stamping foil 410 into a foil drive system 440 of a stamping machine 1, wherein the drive system advances each foil 410 in a determined feed path. The method includes the steps of unwinding an end portion of each foil 410 over a given length, turning each end portion back on itself to constitute the free strand 413 of an open loop 414, unwinding each free strand 413 along the feed path by pulling the corresponding foil 410 from the inside of its loop 414, while partially restraining each free strand 413 as it deploys along the feed path.
Claims19
An insertion method for introducing at least one elongate stamping foil into a foil drive system of a stamping machine for advancing each foil in a determined feed path, the method comprising the steps of:
- providing an end portion of each foil over a given length;
- turning each end portion of foil back on itself to constitute a free strand of an open loop of each foil, the loop having an inside of the loop;
- deploying each free strand along its feed path by pulling on the corresponding foil from the inside of its loop;
- and
- partially restraining each free strand as the free strand deploys along the feed path.
An insertion device for introducing at least one elongate stamping foil into a foil drive system of a stamping machine, wherein the drive system is configured for advancing each foil in a determined feed path;
- the insertion device comprising:
- a holding device configured and located for holding each foil in an insertion position, in which a then leading end portion of the foil is turned back on itself to constitute a free strand of an open loop;
- a deploying device configured and located for deploying each free strand along the feed path by pulling on the corresponding foil from inside of its loop;
- and
- the holding device is further configured for partially restraining each free strand as the deployment device deploys each strand.
