RS 106 Reel Sheeter

Perfectly adaptable to transport paths and local conditions

Connection to the sheet-fed printing press

Sheet-fed printing presses connected to a reel sheeter can be switched from sheet-fed to web-fed operation in just a few minutes.

In web-fed mode, the reel sheeter delivers the cut sheets in-line directly to the pickup roller of the printing machine. The sheet feeder can be filled with new paper stack during that time. When changing from web-fed to sheet-fed operation, the reel sheeter is sent to its parking position so that the sheet feeder of the printing press is freely accessible and can be loaded as usual. The operator can walk around the printing press directly between the sheet feeder and the parked reel sheeter.

The animation below shows such a change with the example of the installation option OS-I[AN1] . Further installation options can be found under  RS 106 installation.

  1. The RS is installed on tracks in front of the sheet feeder.
  2. If sheet material is being processed the RS is sent to its parking position. The feeder stack is now accessible from all sides.
  3. If web material is being processed, the RS is sent to its working position.
    A stack of sheets can remain in the sheet feeder.
  4. The way in which the paper reels are to be mounted depends on the chosen installation option.

General description

The paper web runs as shown in this illustration from an unwinder (M1) through a system of jockey rollers to the infeed point of the cutting unit (M2). Web tension is automatically kept as low as possible. The shearing system ensures a clean cut at a precise angle. The menu-based touch screen is used to set the desired cut-off length to the millimetre and adjust all other process-related parameters. Sheet arrival timing and lateral web position (for the optimisation of the drawing distance) can be adjusted without either tools or any interruptions in the printing process. A decurler is included as standard, and can be activated in order to ensure the necessary level of planeness in the sheets where required (M3).

Once they have run out of the cross cutter, the sheets are shingled in the stream feeding device (M4) and sent to the transport table (M5). In the stream feeding device, each sheet is first decelerated before its trailing edge is lifted by sheet flaps and held by a vacuum system so that the following sheet can pass underneath it. The resultant stream of shingled sheets is conveyed along the transport table to the sheet feeder of the printing press. The suction head is not used. This minimises the risk of bad sheet separation, double sheets etc.

The animation below illustrates the path from the paper reel to the shingled stream of cut sheets:

  1. The web is cut precisely to the required sheet length.
  2. The trailing edge of the incoming sheet is lifted up and held in that position by a suction system.
  3. The following sheet is guided underneath the previous one, thus forming a shingled stream.

Installing the RS 106

MABEG reel sheeters are installed on recessed tracks which can be used to transport both the unwinder and the cutting unit.

We offer the five installation options as shown in this illustration as standard. They enable the optimum integration of the RS 106 into both available space and existing logistics paths within the print shop. If required, we are able to supply specially tailored models that allow the RS 106 to be fitted into even the smallest of spaces. This is a particular advantage when the reel sheeter is to be retrofitted to existing printing presses and there is only a limited amount of space available in front of the sheet feeder.

The arrow marks the loading position of the unwinder. If the paper reels are mounted in the direction of printing, then the unwinder is loaded in its working position. If the paper reels are mounted against the direction of printing, then the unwinder is sent to its lateral parking position for loading.
