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 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 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 special 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.
Automated Cross Fold Unit at the Stahlfolder KH 82-P
With three versions of the cross-fold KL, KZ und KTL 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.
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.
