Abstract
A hot foil stamping press with a pressing table (10) on which a sheet can be advanced, a pressing system (20) for pressing a foil (14) onto the sheet, a guiding system (18) for guiding the foil (14) over the sheet, the guiding system (18) defining a foil transportation path which extends across the path along which the sheet is being advanced, a holder (11) for receiving a supply (12) of foil, and a discarding system (22) for the used foil, the holder being arranged at an operator side of the press.
Claims20
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.

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 a foil onto the sheet;
- a guiding system for guiding the foil over the sheet along a foil transportation path, the foil transportation path extending across and transverse to the feed direction;
- a holder for receiving a supply of the foil;
- a blower for separating used foil from the sheet;
- and
- a discarding system for used foil, wherein
- the holder is arranged at an operator side of the hot foil stamping press and above the pressing table,
- the guiding system is configured to guide the foil in a direction opposite the pressing table after exiting the pressing system,
- the blower and the discarding system are arranged at a side of the hot foil stamping press opposite the operator side, the blower being arranged between the discarding system and the pressing table,
- and the blower is configured to blow air in a direction that is transverse to the feed direction and into a gap between the used foil and the sheet, such that the air acts on the used foil and not on new foil on the sheet, to separate the used foil from the sheet.

- a first holder for receiving a supply of the first foil and a second holder for received a supply of the second foil;
- a discarding system for used foil comprising a waste container;
- and
- a blower for separating used portions of the first foil and used portions of the second foil from the sheet, wherein
- the first holder and the second holder are arranged at an operator side of the hot foil stamping press, the supply of the first foil and the supply of the second foil are on an opposite side of the pressing table as the waste container,
- the first foil and the second foil travel on the foil transportation path with the first foil between the second foil and the sheet, and
- the blower is arranged at a backside of the hot foil stamping press opposite the operator side, between the discarding system and the pressing system, and directs an air stream into a gap between the sheet and the used portions of the first foil and the second foil, such that the air stream acts on the used portions of the first foil and the second foil and not on new foil on the sheet, to separate the used portions of the first foil and the second foil from the sheet.
