EMG Strip Guiding Solutions - more than just components

By using a method patented by EMG which takes into account the strip speed which holds the mandrel in a position control loop a stable control system is possible.

Modern welding or strip joining machines include systems for fully automatic centring upstream and downstream of the welding or strip joining machine.

The two deflector rolls required for bridging strip pass line between accumulator and strip process section are used together with the SRD steering unit, which acts merely proportionally.

Integrally acting guiding rollers can be used if strip guiding is planned after a longer infeed section.

The function of the SRH steering unit is to feed the strip in a well centred manner into the strip accumulator

The HQT system is used where high-precision guiding of the strip is required, e. g. upstream of side trimmers or slitters. It is composed of two independent strip guiding systems, i. e. either guiding on the uncoiler together with the next steering unit or two strip guiding systems in a processing line.

In the case of high strip tensions and/or thick strip it is recommended that a strip guiding system with a three-roll steering unit type SRHT is used for correcting strip travel without deflection of the strip. Achieving a good steering effect necessitates sufficient friction between strip and rolls. The degree of friction is determined by the roll diameter and the dive in position of the mid-roll.

Strip guiding on the recoiler ensures coils with straight lateral surfaces, which prevents damage to strip edges during further transport and handling.
