Benefit from all advantages of our Stahlfolder TH/KH 82 folding machines plus a good piece of profitability on top.
The new Stahlfolder TH 82-P and KH 82-P folding machines are specially designed for the requirements of industrial signature production. Increase your output by up to 50 percent using the shingled folding method. The folding quality and process stability are retained, because there is no need to increase the machine speed.
Due to this high productivity, which corresponds to the productivity of your press, each folding machine can be assigned to one press. This makes your production planning a lot easier and reduces the complexity of processes.
Smart solutions for fast job changes, such as the new Push to Stop function or the new Stahlfolder CombiCurve CC 41 for your Stahlfolder KH 82-P, ensure that this productivity can be converted into a high net output, even at short runs. This ensures the efficiency of the production process and thus your profitability.
With the PFX pallet feeder it is possible for the first time to feed the sheets into the folder in an overlapping sheet stream, no longer individually and with sheet gap as before. Due to the overlapping of the sheets their infeed length reduces by up to 30% and more sheets can be produced at the same machine speed.
The PFX-feeder is optimized to achieve a stable production even with sensible materials and high machine speeds. Especially for the Stahlfolder TH/KH 82-P folding machines, the PFX-feeder is the start of a perfectly matched folder for top productivity.
Moreover, the PFX feeder is very easy to set up, since all settings regarding the AirManagement can be saved and reloaded when needed.
With the PFX feeder you now get the opportunity to integrate the Push to Stop philosophy of Heidelberg into your folder. The feeder can be equipped with a camera system that enables autonomous signature production. This means a change of signatures can take place completely automatically - without active intervention of the operator. Thus, the high productive feeder can be used profitably even for very small runs.
Markfree alignment by AirstreamTable
The AirstreamTable allows for an exact alignment of the sheets without balls and thus without marking risk. The suction wheel transfers the separated sheets from the feeder to the transport belt of the transfer table. This guides the sheets along the rule to the first buckle plate unit. In doing so the sheets are kept on the belt by a low-pressure created by the air stream and can easily and precisely be aligned along the infeed side-lay.
Modular Control Concept: Your key to economy
The Stahlfolder TH/KH 82-P machines are controlled by means of a control in the feeder as well as by intelligent digital sequence controls in the folding units and deliveries. The graphic user interface allows for an easy operation. Direct keys are available for the main functions.
Mobile operation via tablet
Optionally, the TH/KH 82-P folding machines can be equipped with an interface that enables wireless operation via a tablet-PC. Thus, the folding machine can be controlled conveniently from anywhere, for example from the delivery, which reduces time-consuming and tiring walking distances.
Sheet ejection with contact-free control
Besides the mechanical double sheet detector, a sheet ejection with contact-free double sheet monitoring is available for the Stahlfolder TH/KH 82-P. Based on an ultrasonic sound control, sheets lying on top of one another which were picked-up are recognized and actively ejected before they reach the first buckle plate unit. What is important: The sheet ejection is done during machine run and at full production speed. In case of a serial failure, i.e. several double sheets after one another, the machine is stopped before a lot of waste accumulates.
TX-Folding Units for Stahlfolder TH/KH 82-P Folding Machines
Increase productivity without losing quality and process reliability: This is the promise of the new Stahlfolder TH/KH 82-P folding machines. Their innovative fold units allow for a transport of more sheets at the same machine speed – by shingled folding in all three parallel fold units of the Stahlfolder TH 82-P and the parallel and cross-fold unit of the Stahlfolder KH 82-P. This provides two advantages for your production which you can use as needed: High-capacity production of signatures without making cuts regarding quality – or increase of quality, e.g. when processing bible papers without having to accept losses in productivity.
The innovative construction of the fold units allows for a shingled folding of all fold types; this way the infeed length can be reduced by up to 50 percent. While the PFX pallet feeder creates the sheet stream for the first fold unit, additional suction wheels provide the shingling in the follow-up stations of the Stahlfolder TH 82-P. You can also fold the shingled sheet stream in the cross-fold unit of the Stahlfolder KH 82-P and achieve a plus in productivity this way.
The first parallel folding unit of the Stahlfolder TH/KH 82-P comes in working width 82 cm with 6 buckle plates. This is followed by an automated cross-fold unit on the KH 82-P, while the TH 82-P comes with 2 further parallel folding units, each with a working width of 66 cm and 4 buckle plates.
All parallel folding units of the Stahlfolder TH/KH 82-P folding machines are equipped with motorized combination buckle plates.
The cross carrier leads the signatures exactly into the following folding station with one additional suction wheel each for re-shingling the sheets. The oblique rollers are driven by toothed belts completely nonslip: This provides a continuous sheet transport and ideal fold accuracy. Due to the diagonally arranged transport rollers, the signatures are moved reliably to the register sidelay – at all speeds.
With the automated Stahlfolder TH folding machines, such as the TH 82-P, the cross carrier is equipped with a rule with digital display of target and actual value. Here, the control calculates the setting position of the rule. The setting of the rule is done manually in a very simple way, the fine-adjustment is a lot easier thanks to the digital display and can be done very precisely.
The undercarriage of the cross carrier and folding station is constructed in a way that it can easily be swiveled aside at a 45° angle for adjustment work on the slitter shaft station and then returned to its exact position. A magnet on the cross carrier fixes and secures the position.
Automated Cross Fold Unit at the Stahlfolder KH 82-P
With six versions of the cross-fold – from KL with two folding knives up to the complex cross-fold KTLL with three folding knives and integrated buckle plate – we offer you the suitable solution for any requirement.
Regardless of the configuration of the cross fold unit, the sheets are processed continuously shingled here as well.
The automated cross-fold of the Stahlfolder KH 82-P folding machine ensures you uncompromising quality and productivity in a wide range of applications. The constant sheet stop ensures that the signature is stopped, being controlled, and the sheet edges are not deformed. Additional guiding elements like the motor-driven side stops, the belts, the adjustment of which depends on the format and the pneumatically raise able pull wheels at the leading sheet edge transport the sheet exactly and avoid a bouncing back from the sheet stop.
Motor-driven folding roller adjustment
The motorized folding roller gap and slitter shaft gap adjustment are standard with the Stahlfolder TH/KH 82-P. Here, the paper thickness is measured by the sensor of the double sheet detector at the feeder. A previous stacking of paper to feed a learning sheet is not necessary for this. Following that, the control automatically does the setting of the folding roller gaps and the drag of the folding roller – considering fold type and paper features.
Depending on fold type and format the sheet stops of the motor-driven combination buckle plate are positioned and in case of angle alterations the fold length is compensated automatically. An absolute parallelism of the sheet stops is ensured with new orders, even in deflector position.
With combination buckle plates all important buckle plate settings like clearance, buckle space and pretension of the lower buckle-plate lip can be done during running production
Integrated pressing module for top fold quality
The automated pressing device for the Stahlfolder TH 82-P which is integrated into roller frame increases the fold quality and the piling capacity. It is positioned instead of the first pair of slitter shafts thus allowing the additional use of the second pair of slitter shafts for the use of various tools. The liftkit ensures an ergonomic access to the folding unit.
The pneumatic system provides sharp fold edges with folded products up to 3.5 mm thickness and reduces the trapped air in the signature for an ideal transfer of the signature to the following station.
Which delivery you use has a considerable influence on your overall system productivity. It needs to take the strain off the operator without slowing the folding machine down. Therefore, from our wide range of different deliveries, the Peak Performance deliveries from our partner palamides® are most suitable for the highly productive Stahlfolder TH/KH 82-P folding machines.
Particularly fast fold type changes at the Stahlfolder KH 82-P, whenever the cross fold output has to be changed, are possible with the Stahlfolder CombiCurve CC 41. Positioned at the rear cross fold output between the delivery and the folding machine, it vitiates the time-consuming and laborious repositioning of the delivery. The delivery can be moved easily and quickly on a rail system in a straight line.
