RTC 1219 Finishing System
Finishing roll to cut system for variable data printing lines |
The finishing system RTC 1219 is based on the cutter CT 1219 and comprises paper unwinding, traction, drift, longitudinal cut, transversal cut and paper stacking. Some devices are also installed for controlling stationery traction, synchronizing the printer’s paper sheet delivery speed, preventing insufficient or excessive tension applied to the paper.
The term RTC means Roll To Cut. The RTC system is versatile and allows different assembly configurations for space exploitation. Can be set for front and front/back print.
The paper process on the RTC system starts from unwinder, goes through traction and inversion module, longitudinal cut, transversal cut and dispensed on a horizontal conveyor coupled to the cutter.
The cut operation can be made by one knife (single) or two knives (double). The set of double knife is indicated to give more agility to cut documents with bleeding images or folded continuous forms.
The transversal cutter has recourse by margin separation in the set of knifes, which dispenses additional module into the system como fragmentador e container. However, the cutter has condition to adapted coupling of vacuum aspiration ducts margin collector. |
| Brief descriptions of the modules |
|
The unwinder UW 8013 unrolls large volumes of continuous forms at high speed.
The speed control system can increase or reduce roll traction speed, synchronising it with the entire printing line.
It includes a command panel that provides information on equipment status during the operation and sends warning and alert messages in the event of areas or unsuitable conditions.

The turnover TO 9216 is used in front and back printing systems, positioned after the first printer to invert and pull the continuous form. It can also be installed before a longitudinal cutting equipment or transversal cutter.
It has its own motor and form traction control – analog/digital system – that synchronizes the printer’s paper output signal, not enabling gaps or excessive tension on the paper.

The equipment slitter merger ST 2314 performs the operation of longitudinal cutting and overlapping continuous forms, coming from pleated piles or coils. The paper is pulled from tractors and the cut is performed by a circular knife. For operation in printing lines and online finishing, the slitter merger ST 2314 has optical sensors that help to synchronize the paper flow between the printer and the cutter and control the paper’s loop, to compensate the lack or excess of form traction.

The CT 1219 automatic continuous form cutter produces folded piles or rolls. It is generally positioned on finishing lines followed or not by a slitter merger. The sheets can be dispensed on a horizontal piling accumulator belt coupled to the cutter, such as the CV 6018 model.

The Laurenti CV 6018 conveyor stacker accumulates documents in sequential order and provides removal without the need to stop the equipment to which it is attached.

| Additional modules |
|
The Flipper 90º deviates a continuous form by inverting the printing face. It is used in printing systems that do not have the necessary physical space for assembly in line.

|
The traction unit Urge helps pulling continuous forms on the printers. When the printer stops, the traction process is also interrupted due to the low pressure on the paper, preventing an unnecessary paper buildup. The equipment can be used for printing on one or both sides and also with an “H” printing line.

The TD 9215 is used to protect and divert paper on printing lines.
By using the web turn device, front and back printing and be carried out using two printers, side-by-side. The TD 9215 is also used for finishing line and printer maintenance requirements or to provide compatibility when there are different set-ups between the finishing lines for specific jobs.
