Abstract: The invention relates to a flat bed embossing machine (1) comprising a tool plate (20) with a tool side (36) for receiving at least one embossing tool and with a tool plate rear side (35) which lies opposite the tool side (36), further a base plate (10) with a tool plate side (12) which faces the tool plate rear side (35) and with a base plate rear side (11) which is lies opposite the tool plate side (12), for transmitting an embossing force which is exerted upon the tool plate (20), between the tool plate side (12) and the base plate rear side (11), as well as an induction heating appliance (3) for heating the at least one embossing tool (23).

Abstract: A foil web installation for a flat bed embossing machine with foil webs (6), which are conducted across an embossing table (3) from unwinding rolls (7) comprises a braking—and guiding wall (10) ahead of the embossing table and foil feeding devices (9) for several foil webs after the embossing table. Between the unwinding rolls (7) and the embossing table (3) at least one flat braking—and guiding wall (10) acts as a foil tensioning device. This latter element comprises a fixed supporting layer (11) as supporting surface with suction openings (14), a cloth-like contacting layer permeable to air (12) lying on top of it and a flat vacuum chamber (17) with an adjustable vacuum source (13) assigned to it, wherein foil webs (6) are pressed against the braking—and guiding wall (10) and braked as a result of this. This makes possible a foil web installation simple to adjust, easy on the foil web for achieving high embossing performances with the best quality as well as short retooling times.

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.
