This allows you to expand your range with specialized applications, to enter new areas of business, and to add more value as needed. This will ensure your success on into the future.
Regardless of the challenges presented by your folding jobs, you can rely on these machines. Extensive automation options and the high machine availability of our Stahlfolder TH/KH folding machines gives you peace of mind when it comes to production planning. They handle different folding jobs economically, with short throughput times and in constantly high quality. That is a good thing. For you and your customers.
Four feeder variants available – adapted to different requirements
With four feeder variants available, from flat pile feeder, round continuous feeder or pallet feeder up to the high-capacity PFX pallet feeder, there is an ideal configuration for each requirement. The ball-free AirstreamTable provides an easy setting, and ensures mark-free sheet alignment.
At the flat and pallet feeder, the Tremat sheet separator, which is independent of the suction cycle, ensures reliable sheet separation.
Modular Control Concept: Your key to economy
The Stahlfolder TH/KH 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. Due to the modular construction of the control, the functionality of the machine can be enlarged by option kits up to maximum levels of automation.
The operation QuickSetup mode reduces the range of the control to the most important settings. Only sheet format, grammage and fold type must be selected to set up the machine. This does not only avoid set up errors but your folding machine is ready for production with four clicks only. It goes without saying that the professional mode remains available as well so that you can switch between the two operation modes.
Additional devices individualize your products and increase your added value
Additional units like gluing device, water scoring, image inspection, barcode identification as well as sheet ejection can be integrated at the alignment table.
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. 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.
Modular machine concept and wide range of options
For the buckle plate units one to four, various working widths from 56 cm to 96 cm as well as an aligned number of buckle plates (2-8) are available. Combination folders unite the buckle fold with the knife fold principle.
Parallel fold unit
The parallel fold units of the Stahlfolder TH/KH folding machines are equipped with buckle plates with swing deflector or combination buckle plates – depending on the version – possibility of up to 8 buckle plates in the folding unit.
Cross Carrier
The cross carrier leads the signatures exactly into the following folding station. 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, 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.
Cross-Fold Units
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.
Cross-Fold Unit KH Compact
The basic variant cross-fold unit KH Compact with the Stahlfolder KH 66 and 78 folding machines convinces by its ergonomic construction and good manageability. All areas of the cross-fold unit are well accessible, which makes corrections a lot easier: knife height, knife inclination, sheet stops and side stops can be adjusted without any tools at full machine speed and closed noise hood. The slitter shafts can be reached trouble-free at any time as well, thanks to an upper side rack which can be pulled back easily and a square bar which can be taken out.
Automated Cross Fold Unit KH
The automated cross-fold unit of the Stahlfolder KH 66 and KH 82 folders, available in KL, KZ and KTL versions, 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. The optional sheet ejection in the cross-fold avoids jams – a misfolded sheet is detected reliably and ejected without the knife being released.
High folding precision and markfree sheet guidance: the right folding roller technology for precise fold results
Perfect Grip folding roller technology
The innovative Perfect Grip folding roller technology ensures outstanding folding results over the entire length - without compromise. They are less prone to wear and require less maintenance than previous folding roller variants. In addition, the ideal setting range for the folding roller gap is up to two times greater. This makes them more forgiving and reduces set-up times, particularly on manual folding machines, but also on automated folding machines.
The Perfect Grip folding rollers are installed as standard in the parallel fold on all Stahlfolder TH/KH folding machine models. The proven Hard-PU technology is still used in the cross fold of the KH models.
Manual or motor-driven folding roller adjustment
For an exact setting of gaps of folding rollers and slitter shafts, the manual designs are equipped with the proven FESTA-folding roller adjustment. The adjusting knob is simply underlaid with the corresponding number of paper strips; these adjustments are transferred directly and free from play to folding rollers and slitter shafts.
Motor-driven folding roller and slitter shaft spacing adjustment is available as an option. Here, the paper thickness is measured by the integrated sheet thickness measurement 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.
Different buckle plates: The right version for every application
Buckle plates with swing deflector offer high functionality. Combination buckle plates, combination buckle plates in comfort version and motor-driven combination buckle plates convince by top flexibility. Special applications are possible by means of gatefold buckle plates.
Slitter shafts before and after the folding unit: Processes like creasing, perforating and trimming are possible
Front mounted and double rear mounted slitter shafts
Standard equipment is a simple pair of rear-mounted slitter shafts. Front mounted and double rear mounted slitter shafts with lift function are optionally available or can be retrofitted. This way, print shops can easily enlarge their range inline and thus differentiate from their competitors. The double rear mounted slitter shafts clearly optimize the cutting quality with the production of multi-ups in small formats. The slitter shaft lift which is standard integrated in this configuration offers easy accessibility to the first slitter shaft.
Slitter shaft lift in parallel fold
The optional lift for the rear mounted slitter shafts brings the whole slitter shaft component into an ergonomically favorable position for the operator. The access to the slitter shafts has been clearly improved. This makes the setting and changing a lot easier and reduces setup times.
Integrated pressing module for top fold quality
The automated pressing device for all automated Stahlfolder TH folding machines 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.
Integrated belt pressing module for smallest folds
With the automated Stahlfolder TH 56 there is an integrated, automated belt pressing module especially for working width 56 cm for a reliable transport and the pneumatic pressing of miniature folded products up to a minimum of 3.5 cm. The variant with additional, automated slitter shafts and transfer table is mainly used for the first stations, while the direct transfer into the delivery without using tools is sufficient for second stations.
Wide range of deliveries: the optimum delivery for every application
Different delivery systems deliver the sheets after folding. The range of deliveries extends from simple stream deliveries to horizontal stack deliveries, all the way to highly productive stack deliveries. Some deliveries are equipped with pressing rollers for pressing the folded sheets on delivery. This increases folding quality, reduces the pile volume, and facilitates downstream postpress operations. Marking devices stagger the piles laterally, making it easier to remove the folded products. For multiple ups, the individual ups can additionally be separated from one another. 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. We can offer you just the right delivery system for your Stahlfolder folding machine, based on the job, print run and folding machine output.
