RTC Finishing System
Finishing roll to cut system for variable data printing lines
The Laurenti RTC finishing system comprises paper unwinding, traction, deflection, cutting and stacking equipment. 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 Laurenti RTC system is versatile, making it possible to choose from various assembly configurations for achieving the best footprint. It applies to simplex and duplex print systems.
Brief descriptions of the modules

UW 8013

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.
More details
Torre de Inversão
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.
More details
Slitter Merger 2314
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.
More details
1217 C
The CT 1217 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 CT 1217 cutter separates form strips and trimmed margins, which can be sent to the accessory for perforation fragmentation model TC 9114.
More details
Paper Loop
The Paper Loop is an accessory for the online cutting system. This equipment monitors a paper loop, altering cutting speed in the cutter and avoiding paper stretching until it rips or accumulation on the floor.
More details
6018 B
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.
More details
9114
The Trim Chopper TC 9114 transforms the strip and trimmed margins of forms from the Cutter CT 1217 in littles pieces, sending them to the container. The chopper speed can be variable to work in the necessary CT 1217 speed, however it can be changed according to the customer needs.

Additional modules
Flipper 90º
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.
More details
Urge
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.
More details
WTD 9215
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.
