Abstract: A flat embossing machine for flat material (5) to be embossed has a flat press (2), an embossing table (3) and a tool plate (4). At least one foil web (6) passes through foil loop stores (10, 20) each with a differential pressure device (30) for shaping a foil loop (12) with an air pressure difference exerted on the foil web. A foil feed device (24) and a tensioning device (25) are on each side of the flat press and a foil feed control (52) operates in synchronism with the press cycle so that the foil web is stopped during the embossing phase (TP) on the embossing table (3) and is advanced to the next embossing position during the embossing-free phase. Speed differences between the feed speed (VV) at the embossing location and web speed (V7) at the unwinding roll or at the removal device (V8) are compensated for by corresponding increases and decreases in the size of the loops (L1, L2) in the foil stores. This allows high embossing speeds with optimum quality.

Abstract: The embossing or blocking and punching machine with a machine control (2) has several pressure sensors (S1 to S4) for measuring compressive forces X arranged around the center Z of the blocking surface F. A positioning device (10) with a displacement drive (20) and associated motor control (21) is connected to a pressure control program (30) with compressive force control functions (REG), with which is associated a control and display unit (40). Thus, a precise, automatic constant control of the optimum operating pressure (XA) can take place and a constant, maximum embossing or printing quality is achieved.

Abstract: A register draw-in device for sheet printing and embossing machines has two front or leading edge stops and a side stop, and position sensors (S1, S2, S3) for detecting print marks (P1, P2, P3) of a sheet (5). Two detectors (D1, D2) associated with the front stops (A1, A2) detect the sheet leading edge. The front stops are adjustable by control elements (M1, M2) until front print marks (P1, P2) on the sheet are detected by sensors (S1, S2). A control element (M3) then adjusts the side stop (A3) until a side print mark (P3) is detected by another sensor (S3). A system control (11) controls this register correction with the position sensors (S1, S2, S3), the detectors (D1, D2) and the control elements (M1, M2, M3). This accomplishes reliable automatic register correction for each individual sheet and therefore maximum print quality.

Abstract: The die stamping and punching tool has a press upper part (18) and a tool plate (16) and a press lower part (13) with a stamping or pressing table (14) and counterpressure plate (15), the lower part being carried by toggle levers (11, 11') which are moved by a cam mechanism. The controlled rollable stamping or pressing table (14) with the counterpressure plate (15) and rolling profile has a device for controlling the stamping table movement comprising toggle levers (11, 11') and cam disks (12, 12') driving the same, the cam disks (12, 12') having a shape (A,B) related to the rolling profile. The stamping table can be guided by a further cam disk (29). This controllable stamping table guide preferably comprises a table guide lever (28) pivotable about a fulcrum. One end carries a slider (27) sliding in the stamping table and the other end is driven by the cam disk (29), which also has a shape (C,C') related to the rolling profile.
