Unreeling
Overview
Depending on the requirements, a variety of designs for paper and liner unreelings with additional equipment such as web brakes, automatic web guides, festoons, glue units and sealing equipment from Blema are available.
In addition, different types of unwinding frames are available that meet different requirements.
Applications
simple applications
- unreeling without festoons
- web feeding by spiral winder belt
- glue application in gap glue unit
- coil change only during operation at slow speeds (<40 m/min.)
Applications with web material accumulator (festoon)
- unreeling with integrated festoon
- coil change at high speeds possible (>40 m/min.)
high performance applications (controlled web tension)
- separation of web feed and winding process for improved process safety
- driven draw-off rollers (with semi-automatic / automatic splicer)
- controlled, constant, adjustable web tension
- precise web guidance
- shocks from the roll do not continue to the winder
- controlled process
Unreeling - type A (liner, paper)

unreeling web brake glue unit
- paper web tension from the brake
- coils are attached to the frame one behind the other
- manual coil change by crane
- easy to use for low speeds
- inexpensive
Unreeling - typ P (liner, paper, label)
Additional Equipment for Liner Unreelings
Web Brakes
integration into line right before glue application and spiral winder
- increase of web tension
- good uniform bonding of the webs
- use of lowest possible amount of adhesive
- minimizes moisture in the wound tube
web brake, type 155
- friction (heat, dust wear=)
- low braking power
- motor free of wear
- economical
we brake, type 250
- high braking force up to 1500 N
- motor free of wear
- energy recuperation
