摘要:
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.

Webs of printable materials which are fed into a printing machine are provided with a feed tip that allows the web to be rapidly and releasably connected to a the web feed device. The feed tip has a thickened section which is generally perpendicular to the direction of web transport and which cooperates with a carrier element that is fastened to the web feed device. The carrier element has an oblong cavity which extents in the direction of web transport and which cooperates with the thickened portion of the web to form a stop that is perpendicular to the direction of web transport.

Disclosed is a device for inserting a continuous tape. A system comprises a first module (60) and a second module (62). Two traction means (66, 68) can be connected to one another on the intersection (64) and can be detached again. A gripper device (78) transports a continuous tape from the input section (70) of the first module (60) to the output section (72) of the second module (62) when the traction means (66, 68) are connected. The invention also relates to a combined monitoring device.
