Cradle type unwinder with free rollers for heavy loads and packing table equipped with a movable stop and a graduated ruler.

Developed for the confection of conveyor belts or the cutting to length of any material in rolls.

Made to measure and many dimensions available

Unwinder / Rewinder with material tension control by means of a pneumatic puppet.

This range of unwinder / rewinder is the ideal solution to fit on a machine or production line such as large format printers, cutting tables or laser, special machines.

The material tension is adjustable by the touch screen display with a range of use from 12N to 250N.

The working speed automatically adjusts to the speed of the machine moving the material.

Symmetrized pantin with a rack and pinion system allowing to work with off-center material.


Unwinding ensured by a motor reducer and 2 pivoting flywheel bearings with a 30mm square allowing the adaptation of different expandable or not expandable bars.

Standard useful width:

    1650mm
    2050mm
    3200mm

Roller diameters and working speed will be adapted to your needs.

Motorized unwinder with puppet for tension control.

Machine

Motorized rewinder / Unwinder with cantilever expandable shaft Ø74.5mm for Ø76mm cardboard mandrel. The machine is designed to operate at the entrance or exit of an existing production line allowing the unwinding or rewinding of material presented in rolls on a core.

Machine designed for the integration of an unwinding and/or rewinding system on an existing production line or machine. The unwinder / rewinder works autonomously without the need to exchange information with the machine. The operator adjusts the desired material tension and the cycle is automatic (in continuous or step-by-step mode).
The dummy is pneumatically balanced allowing a tension range from 10N to 200N. The guiding system allows a non-centered work commonly used when feeding cutting machines.
This version is equipped with an expandable bar with a joint allowing the coil to be taken out without dismantling the bar, which saves a significant amount of time and effort. The weight of the coil is limited to 40Kg.


A presser with a cutting guide will ensure a perpendicular cut at the end of the winding cycle.


Available options:

    Proportional valve for the tension control by automaton.
    An input/output terminal block allows a data exchange in dry contact with the line: Start/Stop, End of material and Default. (This option also allows the connection of a remote control box).
    Automatic meters with coding wheel to know the length unwound or wound (counting, counting down...)
