• This system with the expansion bodies 58 above the processing roller 5 interacts with the respective spring elements in the form of spring assemblies 67, 67 'and 68, 68' arranged in pairs, which engage under the bearing block 63, 63 'between the two processing rollers at the level of the processing gap.
• These spring assemblies are thus supported between the bearings 44, 45 and 44 ', 45' of the two processing rollers 4 and 5 on the side stands 41 and 42 so that the spring assemblies are integrated into the force flow of the device '1'''.
• machining process punching or punching
• This effect which is characterized by a periodic alternation of movement and standstill phases, causes unwanted vibrations, which are excluded in this system with the spring assemblies.
• a second control unit 64 is connected to the above-described expansion body 58, which in turn interacts with a temperature sensor 65 and one or more heating cartridges 66 in such a way that fine adjustment in the region of the expansion body 58 is achieved Area of the machining gap 59 can be realized. With this change in temperature, the machining gap can be set so variably within a setting range of +/- 0.1 mm, for example by micrometer steps, that a precision adjustment is achieved.
• the adjusting screws 60, 60 allow a corresponding rough adjustment, a dial gauge or the like being provided as a fixed mounting aid in the area of the side stands 41, 42 (not shown) is conceivable.
• the above-described actuating movement is in particular also in the area of the spring assemblies 67, 67 '; 68, 68 'effective.
• the expansion body 58 and the support rollers 61, 61'; 62, 62 ' the parts in the area of the cylinder bearings 44, 45 are placed in a prestressed state, so that an undesired springing apart of the cylinders 4 and 5 is avoided during the machining process under the effect of the punching pressure.
• Expansion body 58 is the formation of the processing rollers 4 and 5 in the area of the bearings 44, 45; 44 ', 45' without the usual bearer ring contacts. These bearing parts are unnecessary in that the support rollers 61, 61 '; 62, 62 'and the preloaded cylinder bearings are integrated in the system of the machine frame. In addition to the upper support rollers 61, 61 '; 62, 62 'are also provided below the lower processing roller 4, respective support rollers 75, 75' and 76, 76 ', which are effective in the manner of the counter-pressure roller 35 (FIG. 3).
• the system described above allows the fine adjustments in the area of the expansion body 58 with little effort, so that both an adaptation of the device 1 '' 'to different material thicknesses of the substrate 2 and a compensation of the tool wear in the area of the punching tools controlled by the control unit 64 are possible.
• the embodiments of the processing device according to the invention thus form an overall structural unit which can also be used in largely similar configurations for embossing, grooving, punching, hologram embossing, numbering or the like.
• FIG. 14 shows, similar to FIG. 8, a basic illustration of the punching device 1 with inclined (angles 69, 69 ', 70 according to FIG. 8) roller bodies 4, 5 and 71, a second processing module 80 being provided upstream of the punching device 1.
• the pair of punching cylinders 4 and 5 and a pair of cylinders 81 and 82 are each arranged at right angles to the longitudinal axis of the machine in such a way that a passage of the substrate in direction A (FIG. 7) is achieved. 14 on this system
• the punching plates shown are each mounted obliquely on the front and rear punching cylinder pair 81, 82 and 4, 5, so that there is a rolling cut for the transverse lines between the respective upper and lower cylinders. The prerequisite for this is that the substrate or the sheets are guided through the device in the same inclined position as the punching plates.
• the advantage of this system is that the processing plates provided for the cylinder pairs 4, 5 and 81, 82 can be manufactured in normal geometry and there is no reduction in the usable punching areas on the substrate.
• the punch lines are worked out twisted by the helix angle.
• the unprinted substrate When the unprinted substrate is passed through, it is grasped at its front edge, guided through the printing station 32 by means of a gripper and printed in a manner known per se by means of printing units (left side, FIG. 14). Then the substrate, which is also held on the front edge by grippers, is gripped in the chain delivery 83 provided as conveyor 33 or the register roller 34 (FIG. 6) and the device 1 or 80 in the region of the lower punch cylinder 4 or 82 with the obliquely mounted gripper to hand over.
• the drive side to the respective operating side is offset in height by the helix angle (dash-dot representations in FIG.
• the gripper bar of the lower processing roller (s) also has the appropriate inclination and the necessary oblique transfer takes place when processing the substrate.
• the gripper bars are also mounted obliquely, so that in the module 80 there is a harmonious transfer of the substrate, which is inclined in the transport direction.
• the substrate is picked up "untwisted" in a position running in the conveying direction A in that the cantilever 86 is also displaced by the helix angle (dash-dot representation).
• the helix angle is 0.5 ° for all of the components described above, the arrangement of which leads to the substrate on the arm 86 being moved parallel to the conveying direction.
