Build on a reliable partnership for your postpress needs and count on the special qualities of Heidelberg with the Stahlfolder BH/CH folding machines.
Three feeder variants available – adapted to different demands
With flat pile feeder, round continuous feeder and pallet feeder, the Stahlfolder BH/CH folding machines offer the required feeding system for every demand.
Flat pile feeder
The flat pile feeder is designed for frequently changing fold jobs with small to medium run lengths. It ensures a perfect sheet separation and is easy to operate. Further advantages are the little space requirements and the low investment costs. The preloading device allows the operator to prepare follow-up jobs already while the current job is running. For this purpose further mobile pile tables, which only need to be exchanged during the set-up, can be loaded on the folder or already on the cutting machine. This minimizes unproductive downtimes.
Round continuous feeder
The round continuous feeders process different kinds of paper in non-stop operation in medium to large runs – wavy sheets and pre-folded, -perforated or -punched products are laid onto an especially long loading table in shingled way. Due to this non-stop feeding the daily production is approx. 20% higher compared to the flat pile feeder. The ergonomic loading height of 94 centimeters is pleasant for the operator and supports a quick loading.
The pallet feeder is the feeder with the lowest expenditure for the operator. Sheets do not need to be pre-piled – in fact the pallet can pull from the delivery of the press directly into the feeder of the folding machine. This reduces the setup time which allows the operator to fully concentrate on the folding and unloading of the sheets. This way the performance of the folding machine can be fully used in one-man-operation. The maximum pallet height of 1.20 meters is ideally matched to the delivery height of a typical sheet-fed printing press.
Sheet separation device Tremat: provides ventilation and pre-separation of the sheets in flat or pallet feeder by means of continuously adjustable blowers at the trailing sheet edge. The Tremat ensures a stable and high productivity of the folding machine with clearly reduced setup time.
Sheet acceleration with suction wheel: A polyurethane-coated suction wheel ensures that the sheets are separated quickly and without markings, accelerated reliably and conveyed onto the register table.
Optional feeder automation: All thickness-relevant settings for folding rollers and slitter shafts are automatically adjusted to the job-specific values.
Modular control system MCT for easy operation of your folding machine
The graphical user interface makes the operation easy. With Touchscreen and QuickSetup all necessary settings are done with just four clicks.
The MCT control system consists of a central control panel at the feeder of the folding machine and integrated control functions, both in the following units as well as in the delivery which offer complete control over the most important machine functions. In the learning mode the sheet length is measured and the suction cycle length and sheet gap are automatically set and continuously monitored.
A gluing attachment and image recognition systems can be integrated at the alignment table. This allows for the production of final products on the folder and increases the added value.
Buckle plate folding units: Top fold accuracy and short setup times
The Stahlfolder BH buckle plate folders offer maximum flexibility for most different folding applications. The single folding units are mobile and can be positioned depending on the fold type. Thanks to the uniform MCT control system of Heidelberg a Stahlfolder BH configuration can also be combined with other Stahlfolder components like modern delivery systems or a mobile knife fold unit.

Cross-fold unit: optimum capacity on little space
With the cross-fold unit of the Stahlfolder CH models the folding is done by means of the downward movement of the folding knives and counter-rotating folding rollers which create the fold. The advantage of the cross-fold unit is that one or more cross-folds can be done on very little space.
Details cross-fold unit:
Cross-fold unit KT in working width 56
The cross-fold unit of the Stahlfolder CH 56 KT auto with motor-driven buckle plate after the folding knife is completely automated – the first time in format range 50 × 70 cm. After entering the job data at the touchscreen all necessary parameters take their positions in a motorized way, both in parallel and in cross-fold section. This reduces your setup times. In larger circulations you score with the constant high output of the Stahlfolder CH 56 KT auto. This makes you very successful also with a hybrid job structure consisting of small runs from digital presses and larger circulations from conventional offset presses.
The ExtraGrip folding rollers with soft PU and optional hard PU avoid markings and ensure an exact, nonslip sheet transport even with difficult papers.
Different buckle plates offer suitable equipment for every application.
Buckle plates with swing deflector
Stahlfolder BH/CH folding machines are equipped with buckle plates with swing deflector by default. They can easily be changed into the swing deflector mode. The buckle plate need not be dismantled from the machine - it is just slightly pulled back and the swing deflector is turned. This procedure saves time and avoids damages.
Automated combination buckle plates
In the positions 1 to 6 automated combination buckle plates can be used as an option. They are equipped with two motors and precise toothed belts to change the position and the angle of the sheet stop. The buckle plates are controlled via the central touchscreen at the feeder. Repeat jobs can be set-up more quickly as stored settings can be retrieved from the memory.
Gate fold buckle plate
The pneumatic gate fold buckle plate allows for a high number of cycles up to 15.000 cycles per hour – with constantly high fold quality. The digital control unit ACC 2.4 controls the switch points of the pneumatic gate fold buckle plate precisely, individually and independent from the fold speed. The pneumatic gate fold buckle plate allows for fold lengths of 6.5 centimeters.
Slitter shafts to enlarge your process steps
The Stahlfolder BH/CH folding machines are equipped with a pair of rear-mounted slitter shafts by default. This allows you to crease, perforate and cut in the folding machine which increases the fold quality and allows for multiple-up production.
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.
