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.
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.
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.
- High number of cycles to increase the fold performance with constantly high fold accuracy
- Setup correction without interrupting running production
- Integration of additional process steps like creasing, perforating, edge trimming
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.
