A medium-high speed splicer ideal for paper, cardboard and other rigid materials
The Model LTX is a medium-high-speed, high-performance splicer that MTorres offers with various configurations, depending on the required splicing speed, and can reach up to 600 m/min (1970 fpm). It is ideal for paper, cardboard and other rigid materials such as laminated papers used in printing, extrusion, lamination processes, etc. The LTX model in its standard configuration is designed to work with floor pick-up type unwinders.
Unwinder LTX-H Auto
Splicing unit to ‘testa’
The Head Splice unit is integrated in a carriage that moves horizontally from the splicing position to the preparation positions. Thanks to the vacuum system in the preparation bars and their ergonomic position, the operator can prepare the new reel in a simple and fast way.
The reliability of splicing with our splicers is close to 100%.„
Depending on the required splicing speed, you can incorporate a double, triple or quadruple hopper to be able to feed material (paper) to the line during the splicing process, without the need to reduce the working speed All the rollers are made of aluminum with the necessary surface treatment depending on the case The hopper is controlled by a floating system activated by a clutch The desired output tension is selected by electronic torque adjustment in the clutch.
The second function of the hopper is to work as a rocker during the unwinding process to maintain constant band tension, absorbing possible tension peaks that may arise. A tension group controlled by an AC motor with a frequency variator helps to control the band tension. A deviation of the hopper from its zero set point affects the speed of the tension group to recover the position without changing the tension. During the splicing cycle, the unit accelerates the new reel, maintaining constant band tension at the splicer outlet.

The splicing is done when the paper band completely detaches from the mandrel
The band must be attached to the mandrel in its entire width, it cannot be partially detached from it
