1. A hot foil stamping press comprising:
a pressing table on which a sheet can be advanced in a feed direction;
a pressing system for pressing foil onto the sheet;
a guiding system for guiding foil over the sheet, the guiding system defining a foil transportation path which extends across a path along which the sheet is being advanced in a direction that is transverse to the feed direction;
a first holder for receiving a first supply of the foil to be supplied to the guiding system;
a second holder for receiving a second supply of the foil;
a discarding system for discarding used foil without rewinding the used foil; and
a blower for separating used foil from the sheet,
wherein the first holder and the second holder are arranged at an operator side of the hot foil stamping press with the second holder being parallel to the first holder and at a greater height relative to the pressing table than the first holder,
the discarding system is arranged at a backside of the hot foil stamping press opposite to the operator side, and the pressing table is arranged between the backside and the operator side,
the blower is arranged at the backside of the hot foil stamping press, between the discarding system and the pressing table, and the blower directs an air stream into a gap between the sheet and the used foil such that the air stream acts on the used foil and not on new foil on the sheet, to separate the used foil from the sheet, and
the operator side including one or more control elements used for adjusting settings of the hot foil stamping press.
