The rewinder is equipped with a coil upender of counter and blades-rotor blades or some other longitudinal decreasing tools. These are positioned transversely with regards to the route of give of your online materials, based on the size of the strips to become acquired by slicing the world wide web fabric through the reel. Various coil upenders have already been analyzed for intelligent placing the rotor blades as a purpose of the content being generated. An illustration of this system to execute stated location is described in EP-A-1245354.
Winding mandrels, which tubular winding cores, related in position, number and dimension on the position, number and dimension in the strips into in which the decreasing equipment divide the net material from the master reel being unwound, have been installed, are put time by period in the rewinder. Machines and devices that prepare the mandrel using the tubular winding cores fixed thereon at present exist. A good example of a system of this kind is defined in WO-A-0061480 as well as in the related Western patent EP-B-1169250.
Downstream of your rewinders the winding mandrels are pulled from the shaped moves, that happen to be then shipped to packaging.
Currently, built-in coil upenders for handling of the various generation techniques through the winder to packaging are not presented. Generally, in presently employed coil upenders you can find three different principal processes. These are:
winding of your nonwoven manufactured by the steady machine,
